Breast Cancer Biopsy
Video Topic : Dr. Gillian Newstead, breast radiologist at The University of Chicago Medical Center, discusses the use of MRI to stage breast cancer, which determines the growth and spread of the disease.
Breast cancer affects one in eight women during their lives. Breast cancer kills more women in the United States than any cancer except lung cancer. No one knows why some women get breast cancer, but there are a number of risk factors. Risks that you cannot change include
- Age - the chance of getting breast cancer rises as a woman gets older
- Genes - there are two genes, BRCA1 and BRCA2, that greatly increase the risk. Women who have family members with breast or ovarian cancer may wish to be tested.
- Personal factors - beginning periods before age 12 or going through menopause after age 55
Other risks include being overweight, using hormone replacement therapy (also called menopausal hormone therapy), taking birth control pills, drinking alcohol, not having children or having your first child after age 35 or having dense breasts.
Symptoms of breast cancer may include a lump in the breast, a change in size or shape of the breast or discharge from a nipple. Breast self-exam and mammography can help find breast cancer early when it is most treatable. Treatment may consist of radiation, lumpectomy, mastectomy, chemotherapy and hormone therapy.
Men can have breast cancer, too, but the number of cases is small.
A biopsy is a procedure that removes a small piece of living tissue from your body. The tissue is examined with a microscope for signs of damage or disease. Biopsies can be done on all parts of the body. A biopsy is the only test that can tell for sure if a suspicious area is cancer. But biopsies are performed for many other reasons too.
There are different ways to do a biopsy. A needle biopsy removes tissue with a needle passed through your skin to the site of the problem. Other kinds of biopsies require surgery.
