Mesothelioma Medical Dictionary and Medical Terms

The following list of Mesothelioma medical terms, definitions, and explanations are commonly used in the treatment of malignant Mesothelioma.

Our intention is to help those diagnosed with Mesothelioma gain a better understanding of the most common and some uncommon terms related to a Mesothelioma.

New definitions and new medical terms are being added each month.

A - Mesothelioma Medical Dictionary

Abdominal Mesothelioma

Adjuvant therapy (add- joo-vunt): treatment used in addition to the main treatment. It usually refers to hormonal therapy, chemotherapy, or radiation added after surgery to increase the chances of curing the disease or keeping it in check.

Adrenal gland:one adrenal gland is located near each kidney. Their main function is to produce hormones which control metabolism, fluid balance, and blood pressure. In addition, they produce small amounts of "male" hormones (androgens) and "female" hormones (estrogens and progesterone).

Advanced Cancer

Advance directives:legal documents that tell the doctor and family what a person wants for future medical care, including whether to start or when to stop life-sustaining treatment.

AJCC Staging System

Alcohol and Mesothelioma

AlimtaŽ Plus Cisplatin Clinical Trial

AlimtaŽ (Mesothelioma Drug)

Alimta used in Chemotherapy

Alopecia (al-o-pee- shuh):hair loss. This often occurs as a result of chemotherapy or, less often, from radiation therapy to the head. In most cases, the hair grows back after treatment ends.

Alveoli (al- vee -o-lie):air cells of the lungs.

Alternative and complementary therapies:therapy refers to any of the measures taken to treat a disease. Unproven therapy is any therapy that has not been scientifically tested and approved. Use of an unproven therapy instead of standard therapy is called alternative therapy. Some alternative therapies have dangerous or even life-threatening side effects. For others, the main danger is that a patient may lose the opportunity to benefit from standard therapy. Complementary therapy, on the other hand, refers to therapies used in addition to standard therapy. Some complementary therapies may help relieve certain symptoms of cancer, relieve side effects of standard cancer therapy, or improve a patient's sense of well-being. The ACS recommends that patients considering use of any alternative or complementary therapy discuss this with their health care team.

Anemia (uh- neem-ee-uh): low red blood cell count.

Anesthesia (an- es-the-zuh): the loss of feeling or sensation as a result of drugs or gases. General anesthesia causes loss of consciousness ("puts you to sleep"). Local or regional anesthesia numbs only a certain area.

Angiogenesis (an-gee-o-JEN-uh-sis):the formation of new blood vessels. Some cancer treatments work by blocking angiogenesis, thus preventing blood from reaching the tumor.

Anterior Mediastinal Mass

Antibiotic: drugs used to kill organisms that cause disease. Antibiotics may be made by living organisms or they may be created in the lab. Since some cancer treatments can reduce the body's ability to fight off infection, antibiotics may be used to treat or prevent these infections.

Antibody:a protein in the blood that defends against foreign agents, such as bacteria. These agents contain certain substances called antigens. Each antibody works against a specific antigen. (See also antigen.)

Anti-Cancer Drugs

Antiemetic (an- ti-eh-MEH-tik):a drug that prevents or relieves nausea and vomiting, common side effects of chemotherapy.

Anti-estrogen:a substance (for example, the drug tamoxifen) that blocks the effects of estrogen on tumors. Anti-estrogens are used to treat breast cancers that depend on estrogen for growth.

Antigen (an- tuh-jen):a substance that causes the body's immune system to react. This reaction often involves production of antibodies. For example, the immune system's response to antigens that are part of bacteria and viruses helps People resist infections. Cancer cells have certain antigens that can be found by laboratory tests. They are important in cancer diagnosis and in watching response to treatment. Other cancer cell antigens play a role in immune reactions that may help the body's resistance against cancer.

Antimetabolites (an-tie- meh-TAB-o-lites):substances that interfere with the body's chemical processes, such as those creating proteins, DNA, and other chemicals needed for cell growth and reproduction. In treating cancer, antimetabolite drugs disrupt DNA production, which in turn prevents cell division and growth of tumors. (See also DNA.)


Aspirate (as- pir -ate):to draw in or out by suction. See needle aspiration.

Asymptomatic (a- simp-to-MAT-ik):not having any symptoms of a disease. Many cancers can develop and grow without producing symptoms, especially in the early stages. Screening tests such as mammograms help to find these early cancers, when the chances for cure are usually highest. (See also screening.)

Atypical (a-tip-uh- kul):not usual; abnormal. Often refers to the appearance of cancerous or precancerous cells. (See also hyperplasia.)

Autologous bone marrow transplantation (aw- tahl-uh-gus): Also see bone marrow transplantation.

Axilla (ax- il -la):the armpit.

Axillary dissection (ax- il-lair-ee):removal of the lymph nodes in the armpit (axillary nodes). They are examined for the presence of cancer.

B - Mesothelioma Medical Dictionary

Barium enema:(also called a double contrast barium enema) a method used to help diagnose colorectal cancer. Barium sulfate, a chalky substance, is used to partially fill and open up the colon. When the colon is about half-full of barium, air is inserted to cause the colon to expand. This allows good x-ray films to be taken.

Basal cell carcinoma:the most common non-melanoma skin cancer. It begins in the lowest layer of the epidermis, called the basal cell layer. It usually develops on sun-exposed areas, especially the head and neck. Basal cell cancer is slow-growing and is not likely to spread to distant parts of the body.

Benign (be-nine):not cancer; not malignant.

Benign tumor:an abnormal growth that is not cancer and does not spread to other areas of the body.

Benign prostatic hyperplasia or BPH (be-nine pros- tah -tick hy-per-PLAY-zuh):non-cancerous enlargement of the prostate that may cause problems with urination such as trouble starting and stopping the flow. \

Bilateral (bi-lat- er-ul):on both sides of the body; for example, bilateral breast cancer is cancer in both breasts.

Biologic response modifiers:substances that boost the body's immune system to fight against cancer; interferon is one example. Also called biologic therapy.


Biopsy (buy-op-see): the removal of a sample of tissue to see whether cancer cells are present. There are several kinds of biopsies. In some, a very thin needle is used to draw fluid and cells from a lump. In a core biopsy, a larger needle is used to remove more tissue.

Blocking of ERK1 and ERK2

Biphasic Mesothelioma

Blood count: a count of the number of red blood cells and white blood cells in a given sample of blood.

Bone marrow: the soft tissue in the hollow of flat bones of the body that produces new blood cells.

Bone marrow aspiration and biopsy: a procedure in which a needle is placed into the cavity of a bone, usually the hip or breast bone, to remove a small amount of bone marrow for examination under a microscope.

Bone marrow transplant: a complex treatment that may be used when cancer is advanced or has recurred, or as the main treatment in some types of leukemia. The bone marrow transplant makes it possible to use very high doses of chemotherapy that would otherwise be impossible. Autologous bone marrow transplant means that the patient's own bone marrow is used. An allogeneic bone marrow transplant uses marrow from a donor whose tissue type closely matches the patient's.

Bone scan: an imaging method that gives important information about the bones, including the location of cancer that may have spread to the bones. It can be done on an outpatient basis and is painless, except for the needle stick when a low-dose radioactive substance is injected into a vein. Pictures are taken to see where the radioactivity collects, pointing to an abnormality.

Brain scan: an imaging method used to find anything not normal in the brain, including brain cancer and cancer that has spread to the brain from other places in the body. This scan can be done in an outpatient clinic. It is painless, except for the needle stick when a radioactive substance is injected into a vein. The pictures taken will show where radioactivity collects, indicating an abnormality.

Bone survey (skeletal):an x-ray of all the bones of the body; often done when looking for metastasis to the bones.

Brachytherapy (break- ee-ther-uh-pee):internal radiation treatment given by placing radioactive material directly into the tumor or close to it. Having this treatment does not make a person radioactive, except while the material remains in the body. It is usually removed in a few hours.

Bronchi (bron-ki):in the lungs, the two main air passages leading from the windpipe (trachea). The bronchi provide a passage for air to move in and out of the lungs.

Bronchiole (brong-key-ol):one of the smaller sub-divisions of the bronchi.

Bronchopleural Fistula

Bronchoscopy (bron-kos-ko-pee): examination of the bronchi using a flexible, lighted tube called a bronchoscope.

CEA: carcinoembryonic antigen (car-sin-o- em-bre-ON-ic an- tuh-jin): antigens found in fetal tissue. If found in an adult it may be specific to cancerous tumors. Tests for these antigens may help in diagnosing cancer and in finding out if the cancer has spread

CT scan: computed tomography (tom- og-ruh-fee): an imaging test in which many x-rays are taken of a part of the body to produce cross-sectional pictures of internal organs. Except for the injection of a dye (needed in some but not all cases), this is a painless procedure that can be done in an outpatient clinic. It is often referred to as a "CT" or "CAT" scan.

Cancer: cancer is not just one disease but rather a group of diseases. All forms of cancer cause cells in the body to change and grow out of control. Most types of cancer cells form a lump or mass called a tumor. The tumor can invade and destroy healthy tissue. Cells from the tumor can break away and travel to other parts of the body. There they can continue to grow. This spreading process is called metastasis. When cancer spreads, it is still named after the part of the body where it started. For example, if breast cancer spreads to the lungs, it is still breast cancer, not lung cancer.

Cancer care team: the group of health care professionals who work together to find, treat, and care for People with cancer. The cancer care team may include any or all of the following and others: primary care physician, pathologist, oncology specialists (medical oncologist, radiation oncologist), surgeon, nurse, oncology nurse specialist, oncology social worker. Whether the team is linked formally or informally, there is usually one person who takes the job of coordinating the team.

Cancer-related checkup: a routine health examination for cancer in persons without obvious signs or symptoms of cancer. The goal of the cancer-related checkup is to find the disease, if it exists, at an early stage, when chances for cure are greatest. Clinical breast examinations, Pap smears, and skin examinations are examples of methods used in cancer-related checkups. (See also detection.)

Carcinogen (car-sin-o-gin): Any substances that cause cancer or helps cancer grow. For example, tobacco smoke contains many carcinogens that greatly increase the risk of lung cancer.

Carcinoma (car-sin-o-ma): a malignant tumor that begins in the lining layer (epithelial cells) of organs. At least 80% of all cancers are carcinomas.

Carcinoma in situ (car-sin-o-ma in sigh-too): an early stage of cancer in which the tumor is confined to the organ where it first developed. The disease has not invaded other parts of the organ or spread to distant parts of the body. Most in situ carcinomas are highly curable.

Case manager: the member of a cancer care team, usually a nurse or oncology nurse specialist, who coordinates the patient's care throughout diagnosis, treatment, and recovery. The case manager is a new concept that provides a guide through the complex system of health care by helping cut through red tape, getting responses to questions, managing crises, and connecting the patient and family to needed resources.

Catheter (cath-eh-tur): a thin, flexible tube through which fluids enter or leave the body.

Cell: he basic unit of which all living things are made. Cells replace themselves by splitting and forming new cells (mitosis): The processes that control the formation of new cells and the death of old cells are disrupted in cancer.

Chemoprevention (key-mo-pre-VEN-shun): prevention or reversal of disease using drugs, chemicals, vitamins, or minerals. While this idea is not ready for widespread use, it is a very promising area of study. The Breast Cancer Prevention Trial has shown that the drug tamoxifen can prevent some cases of breast cancer among women with high risk of the disease. But the drug may have some serious side effects.

Chemotherapy (key-mo-THER-uh-pee): treatment with drugs to destroy cancer cells. Chemotherapy is often used with surgery or radiation to treat cancer when the cancer has spread, when it has come back (recurred), or when there is a strong chance that it could recur.

Colony stimulating factors (CSF): types of growth factors that promote growth and division of blood-producing cells in the bone marrow. CSFs are naturally produced in the body. But extra amounts may be given as a treatment to reduce or prevent certain side effects of chemotherapy due to not having enough blood cells.

Colostomy (co-loss-tuh-me): an opening in the abdomen for getting rid of body waste (stool). A colostomy is sometimes needed after surgery for cancer of the rectum.

Combined modality therapy: two or more types of treatment used alternately or together to get the best results. For example, surgery for cancer is often followed by chemotherapy to destroy any cancer cells that may have spread from the original site.

Complementary treatment: see alternative and complementary therapy

DRE:stands for digital rectal exam. The doctor inserts a gloved finger into the rectum to feel for anything not normal.

Detect Pleural Mesothelioma Early Stages

Detection finding disease: Early detection means that the disease is found at an early stage, before it has grown large or spread to other sites. Note: many forms of cancer can reach an advanced stage without causing symptoms. Mammography can help to find breast cancer early, and the PSA blood test is useful in finding prostate cancer.

Diagnosis: identifying a disease by its signs or symptoms, and by using imaging procedures and laboratory findings. The earlier a diagnosis of cancer is made, the better the chance for long-term survival.

Epidemiology (ep-uh-deem-ee-AHL-uh-gee): the study of diseases in populations by collecting and analyzing statistical data. In the field of cancer, epidemiologists look at how many People have cancer; who gets specific types of cancer; and what factors (such as environment, job hazards, family patterns, and personal habits, such as smoking and diet) play a part in the development of cancer.

Esophageal speech (eh-sof-eh-JEE-uhl): a special type of speech used by some People after surgery for cancer of the voice box (larynx). Air is swallowed and a "belching" type of speech can be produced. New devices, improved surgery, and the use of chemotherapy and radiation therapy instead of surgery, have reduced the need for learning esophageal speech.

Etiology (ee-tee-ahl-eh-jee): the cause of a disease. In cancer, there are probably many causes, although research is showing that both genetics and lifestyle are major factors in many cancers.

Fine needle aspiration: see needle aspiration.

Five-year survival rate: the percentage of People with a given cancer that are expected to survive five years or longer with the disease. Five year survival rates have some drawbacks. Although the rates are based on the most recent information available, they may include data from patients treated several years earlier. Advances in cancer treatment often occur quickly. Five-year survival rates, while statistically valid, may not reflect these advances. They should not be seen as a predictor in an individual case.

Flow cytometry(flow cy-tom-uh-tree): a test of tumor tissue to see how fast the tumor cells are reproducing and whether the tumor cells contain a normal or abnormal amount of DNA. This test is used to help predict how aggressive a cancer is likely to be. (See also ploidy, DNA, S-phase fraction.)

Frozen section: a piece of tissue that has been quick-frozen and then examined under a microscope. This method gives a quick diagnosis, sometimes while the surgeon is waiting to complete a procedure. The diagnosis is confirmed in a few days by a more detailed study called a permanent section. (See also permanent section.)

G - Mesothelioma Medical Dictionary

Gene:a segment of DNA that contains information on hereditary characteristics such as hair color, eye color, and height, as well as susceptibility to certain diseases. Women who have BRCA1 or BRCA2 gene mutations (defects) have an inherited tendency to develop breast cancer.

Genetic testing: tests performed to see if a person has certain gene changes known to increase cancer risk. Such testing is not recommended for everyone, rather for those with specific types of family history. Genetic counseling should be part of the process as well.

Gene therapy: a new type of treatment in which defective genes are replaced with normal ones. The new genes are delivered into the cells by viruses or proteins.

Gemcitabine (Gemzar)

Genetically-Encoded Protein Calretinin

Genetic Test Offers Earlier Detection of Mesothelioma


Glands: a cell or group of cells that produce and release substances used nearby or in another part of the body.

Gleason score: a method of grading prostate cancer cells on a scale of 2 to 10. The higher the number, the faster the cancer is likely to grow.

Grade: the grade of a cancer reflects how abnormal it looks under the microscope. There are several grading systems for cancer, such as the Gleason score for prostate cancer. Each grading system divides cancer into those with the greatest abnormality (poorly differentiated), the least abnormality (well-differentiated), and those in between (moderately differentiated). Grading is done by the pathologist who examines the tissue from the biopsy. It is important because higher grade cancers tend to grow and spread more quickly and have a worse prognosis.

Grim Prognosis

Growth factors: a naturally occurring protein that causes cells to grow and divide. Too much growth factor production by some cancer cells helps them grow quickly, and new treatments to block these growth factors are being tested in clinical trials. Other growth factors help normal cells recover from side effects of chemotherapy.

Histologic Subtype for Malignant Mesothelioma

Histology: Means the specific type of Mesothelioma cancer cells that are found.

Hodgkin's disease: an often curable type of cancer that affects the lymphatic system. Named for the doctor who first identified it.

Hormone: a chemical substance released into the body by the endocrine glands such as the thyroid, adrenal, or ovaries. The substance travels through the bloodstream and sets in motion various body functions. For example, prolactin, which is produced in the pituitary gland, begins and sustains the production of milk in the breasts after childbirth.

Hormone therapy: treatment with hormones, drugs that interfere with hormone production or hormone action, or surgical removal of hormone-producing glands to kill cancer cells or slow their growth. The term also applies to the replacement of other hormones (androgens, thyroid, etc.) that are deficient because of organ failure.

Hospice: a special kind of care for People in the final phase of illness, their families and caregivers. The care may take place in the patient's home or in a homelike facility.

Immunology (im-mune-ahl-o-jee): study of how the body resists infection and certain other diseases. Knowledge gained in this field is important to those cancer treatments based on the principles of immunology.

Immunosuppression (im-mune-no-suh-PREH-shun): a state in which the body's immune system does not respond as it should. This condition may be present at birth, or it may be caused by certain infections (such as human immunodeficiency virus or HIV), or by certain cancer therapies, such as cancer-cell killing (cytotoxic) drugs, radiation, and bone marrow transplantation.

Immunotherapy (im-mune-no-THER-uh-pee): treatments that promote or support the body's immune system response to a disease such as cancer.

Interstitial radiation therapy (in- ter-stih-shul radiation therapy): a type of treatment in which a radioactive implant is placed directly into the tissue (not in a body cavity).

Interrogatory: A set of questionnaires exchanged by the parties during the discovery process.

Invasive cancer: cancer that has spread beyond the area where it first developed to involve adjacent tissues. For example, invasive breast cancers develop in milk glands (lobules) or milk passages (ducts) and spread to the nearby fatty breast tissue. Some invasive cancers spread to distant areas of the body (metastasize), but others do not.

Lymphatic system: the tissues and organs (including bone marrow, spleen, thymus, and lymph nodes) that produce and store lymphocytes (cells that fight infection) and the channels that carry the lymph fluid. The entire lymphatic system is an important part of the body's immune system. Invasive cancers sometimes penetrate the lymphatic vessels (channels) and spread (metastasize) to lymph nodes.

Lymph (limf): clear fluid that flows through the lymphatic vessels and contains cells known as lymphocytes. These cells are important in fighting infections and may also have a role in fighting cancer.

Lymph nodes: small bean-shaped collections of immune system tissue such as lymphocytes, found along lymphatic vessels. They remove cell waste and fluids from lymph and help fight infections.

Lymphocytes: a type of white blood cell that helps the body fight infection.

Lymphoma (lim -foam-uh): a cancer of the lymphatic system, a network of thin vessels and nodes throughout the body. Its function is to fight infection. Lymphoma involves a type of white blood cells called lymphocytes. The two main types of lymphoma are Hodgkin's disease and non-Hodgkin's lymphoma. The treatment methods for these two types of lymphomas are very different.

Needle aspiration: a type of needle biopsy. Removal of fluid from a cyst or cells from a tumor. In this procedure, a needle is used to reach the cyst or tumor, and with suction, draw up (aspirate) samples for examination under a microscope. If the needle is thin, the procedure is called a fine needle aspiration or FNA. (See also biopsy.)

Needle biopsy: removal of fluid, cells, or tissue with a needle for examination under a microscope. There are two types: fine needle aspiration (FNA) and core biopsy. FNA uses a thin needle to draw up (aspirate) fluid or small tissue fragments from a cyst or tumor. A core needle biopsy uses a thicker needle to remove a cylindrical sample of tissue from a tumor.

Needle localization: a procedure used to guide a surgical breast biopsy when the lump is hard to locate or when there are areas that look suspicious on the x-ray but there is not a distinct lump. A thin needle is placed into the breast. X-rays are taken and used to guide the needle to the suspicious area. The surgeon then uses the path of the needle as a guide to locate the abnormal area to be removed.

Remission: complete or partial disappearance of the signs and symptoms of cancer in response to treatment; the period during which a disease is under control. A remission may not be a cure.

Rescue treatment: procedures or treatments such as bone marrow transplantation that "rescue" a patient's immune system and blood-forming organs from the effects of high dose chemotherapy.

Resection: surgery to remove part or all of an organ or other structure.

Risk factor: anything that increases a person's chance of getting a disease such as cancer. Different cancers have different risk factors. For example, exposure to sunlight is a risk factor for skin cancer, smoking is a risk factor for lung and other cancers, and a high-fat, low-fiber diet is a risk factor for colorectal cancer. Some risk factors, such as smoking, can be controlled. Others, like a person's age, can't be changed.

To make this information somewhat clearer, the TNM descriptions can be grouped together into a simpler set of stages, labeled with Roman numerals. In general, the lower the number, the less the cancer has spread. A higher number means a more serious cancer.
