Adjuvant chemotherapy – The administration of chemotherapy after surgery or radiation treatment for cancer.  This round of chemotherapy follows on the main treatment to help take care of any remaining malignant cells.

Adjuvant therapy – More general than adjuvant chemotherapy, adjuvant therapy refers to any treatment administered following the main treatment. This might be chemotherapy, but it also might be radiation or hormone therapy, or other treatments.

ADT – Androgen Deprivation Therapy

Alkylating Agents – Chemotherapy drugs that chemically link to cellular DNA and thereby prevent mitosis.  This stops growths in the body, including malignant tumors.

Androgen Deprivation Therapy – Administration of anti-hormone agents.  Used in treatment of prostate cancer.

Anemia – A clinical condition when the patient has insufficient red blood cells to carry oxygen that the body demands.  As a result, the patient feels tired and may have other complications.  Common side effect of chemotherapy drugs.

Angiogenesis – Growth and development of new blood vessels. Happens when an organism grows. Cancerous tumors rely on angiogenesis to grow.

Antibody conjugates – Armed antibodies or empowered antibodies.  Explained here.

Antineoplastic – Inhibiting the development of abnormal tissue growth.  Anti-cancer drugs are antineoplastic.

Anthracyclines – Class of antibiotics derived from bacteria and used to treat cancer.  Used on a wide range of cancers.  More.

Antibody – Proteins that act as agents of the immune system.  The immune system produces these proteins to deal with (and possibly neutralize) foreign materials.  Immunotherapy uses exogenous antibodies (often manmade) to address diseases, including cancer.  The proteins are also called immunoglobulins.

Antiemetic – Anti-nausea medicine used to stop vomiting and feeling sick-to-the-stomach, which are common side effects of chemotherapy medicines.

Antifolate – Class of chemotherapy medicines that stop mitosis by inhibiting the action of folic acid in the cellular metabolism.

Antigen – Cell, organism, or chemical that induces a specific immune response inside the body.
