Information for Patients


Breast Diseases

Most women experience breast changes at some time. Your age, hormone levels, and medicines you take may cause lumps, bumps, and discharges (fluids that are not breast milk).

If you have a breast lump, pain, discharge or skin irritation, see your health care provider. Minor and serious breast problems have similar symptoms. Although many women fear cancer, most breast problems are not cancer.

Breast Reconstruction

If you need a mastectomy, you have a choice about whether or not to have surgery to rebuild the shape of the breast. Instead of breast reconstruction, you could choose to wear a breast form that replaces the breast, wear padding inside your bra, or do nothing. All of these options have pros and cons. What is right for one woman may not be right for another.

Breast reconstruction may be done at the same time as the mastectomy, or it may be done later on. If radiation therapy is part of the treatment plan, your doctor may suggest waiting until after radiation therapy.

If you're thinking about breast reconstruction, talk to a plastic surgeon before the mastectomy, even if you plan to have your reconstruction later on.

A surgeon can reconstruct the breast in many ways. Some women choose to have breast implants, which are filled with saline or silicone gel. Another method uses tissue taken from another part of your body. The plastic surgeon can take skin, muscle, and fat from your lower abdomen, back, or buttocks.

The type of reconstruction that is best for you depends on your age, body type, and the type of cancer surgery that you had. A plastic surgeon can help you decide.
