Patient Education

Fluorouracil Injection


Fluorouracil is generally used in combination with other medications to treat colon cancer or rectal cancer (cancer that begins in the large intestine) that has gotten worse or spread to other parts of the body. Fluorouracil is used in combination with other medications to treat certain types of breast cancer after surgery to remove the tumor or radiation therapy. Fluorouracil is also used to treat cancer of the pancreas and stomach cancer. Fluorouracil is in a class of medications called antimetabolites. It works by slowing or stopping the growth of cancer cells in your body.

Cancer Chemotherapy


Normally, your cells grow and die in a controlled way. Cancer cells keep growing without control. Chemotherapy is drug therapy for cancer. It works by killing the cancer cells, stopping them from spreading, or slowing their growth. However, it can also harm healthy cells, which causes side effects.

You may have a lot of side effects, some, or none at all. It depends on the type and amount of chemotherapy you get and how your body reacts. Some common side effects are fatigue, nausea, vomiting, pain, and hair loss. There are ways to prevent or control some side effects. Talk with your health care provider about how to manage them. Healthy cells usually recover after chemotherapy is over, so most side effects gradually go away.

Your treatment plan will depend on the cancer type, the chemotherapy drugs used, the treatment goal, and how your body responds. Chemotherapy may be given alone or with other treatments. You may get treatment every day, every week, or every month. You may have breaks between treatments so that your body has a chance to build new healthy cells. You might take the drugs by mouth, in a shot, as a cream, or intravenously (by IV).
