Anticipatory Nausea and Vomiting can sometimes affect people who suffered nausea and vomiting as a result of previous cancer treatments. It can be triggered by things that a person associates with chemotherapy and radiation therapy, including smells, tastes, objects or images.

Benign means not cancer; not malignant.

Biopsy is the removal of tissue to determine whether cancer cells are present.

Cancer is a malignant tumor of potentially unlimited growth that has the ability to spread throughout the body.

Chemotherapy is the treatment with drugs to destroy cancer cells.

Chemotherapy-induced Nausea and Vomiting (CINV) usually begins with a queasy feeling in the stomach, which may be caused by chemotherapy.

Emesis usually refers to nausea or vomiting, but can also include retching.

Malignant Tumor is a mass of cancer cells that may invade surrounding tissues or spread (metastasize) to different areas of the body.

Nausea is the queasy feeling in the stomach that may lead to the urge to vomit.

Post-Operative Nausea and Vomiting (PONV) is the queasy and unpleasant feeling in the stomach that many people may feel after undergoing some surgical procedures.

Radiation Therapy is the use of high-energy rays (x-rays or gamma rays) for cancer treatment. Radiation may be used as the main treatment for cancer, to reduce the size of a cancer before surgery or to reduce some of the symptoms of cancer. Radiation therapy is also used to destroy remaining cancer cells after surgery.

Radiation Therapy-induced Nausea and Vomiting (RINV) is similar to CINV, but it is caused by radiation therapy.

Remission is a period of time when the cancer is responding to treatment or is under control.

Retching is sometimes called "dry heaves." This is the body’s attempt to vomit but does not remove contents from the stomach.

Vomiting is the forcible removal of the contents of the stomach through the mouth.
