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.
