Each chemotherapy drug belongs to a class of drugs. Each class has a different effect on cancer cells. That is why different anti-cancer drugs are often used in combination with each other. The major drug classes are described below.

Many women are afraid of having chemotherapy because of its side effects and the toll it can take on the body. Although chemotherapy does have a dramatic effect on the body, it is often a successful treatment. It reduces the risk of cancer returning after surgery. Doctors know more about chemotherapy than ever before. The doses are more accurate and there are a variety of medications to help minimize side effects.
Expect some changes in your life during chemotherapy. Your daily routine will be affected. You may be able to keep working and doing your normal activities. Or you may be too tired to do all the things you normally do. That’s okay. Your co-survivors (friends and family) can help. You will start to feel better once the treatment is over. Until then, your doctor and nurses can give you suggestions on how to manage your daily activities.
