Test Overview
A breast self-examination (BSE) involves
checking your breasts to help detect breast problems or changes. Many breast
problems are first discovered by women themselves, often by accident. Breast
lumps can be noncancerous (benign) or cancerous (malignant).
Breast cancer can occur at any age, though it is most
common in women older than 50.
Medical experts disagree about the
need for regular breast self-examinations. A large study showed that regular
breast self-examinations led to more doctor visits but did not find breast
cancer earlier than regular medical examinations.1
The U.S. Preventive Services Task Force (USPSTF) and the Canadian Task Force on
Preventive Health Care (CTFPHC) found no evidence that BSE saves lives, and
they do not recommend routine breast self-examinations.2, 3 The American Cancer Society
considers breast self-examination an option for women. Talk with your health
professional about breast self-examination.
A breast
self-examination involves checking your breasts for lumps or changes while
standing and lying in different positions and while looking at your breasts in
a mirror to note any changes in their appearance. Once you know what your
breasts normally look and feel like, any new lump or change in appearance
should be evaluated by a health professional. Most breast problems or changes
are not because of cancer.
If you choose to do breast
self-examinations, this should not replace regular
clinical breast examinations (CBE) by a health
professional and
mammograms if you are older than age 40. Breast
implants do not decrease a woman's risk for breast cancer, so women with breast
implants need to talk with their health professionals about performing breast
self-examinations.
