Breast Cancer - Treatment Overview

When making decisions about treatment, you and your doctor will consider many things, such as your age and health, the type of breast cancer you have, and how likely it is to spread.

Breast cancer is usually treated with surgery, radiation therapy, chemotherapy, hormone therapy, or targeted therapy.

Types of treatment

In some cases, chemotherapy or hormone therapy is used before surgery to shrink the breast cancer. This may mean that less breast tissue has to be removed during surgery.

Depending on the tumor's size and whether cancer has spread to your lymph nodes, you may have several treatment options. Hormone therapy, chemotherapy, or a combination of the two treatments may be used after surgery to destroy any remaining cancer cells. This also lowers the chances that the cancer will come back. Your doctor may suggest gene tests to find out if chemotherapy will help.

For women with DCIS (ductal carcinoma in situ), surgery is the standard treatment. But researchers are trying to find out which women might be good candidates for active surveillance. These women might be able to safely avoid or delay surgery.

Side effects of treatment

Treatments can have side effects, such as nausea and vomiting and hair loss. For more information on how to manage side effects, see Home Treatment.
