Breast Cancer Detection Fact Sheet
Breast self-exam (BSE) is not recommended as a screening tool for breast cancer. However, it is important to become familiar with the way your breasts normally look and feel. Knowing what is normal for you may help you see or feel changes in your breasts.
See your health care provider if you notice any of these warning signs of breast cancer (see pictures) [52-55]:

Many women’s breasts feel lumpy. Breast tissue naturally has a bumpy texture that varies from one woman to another. For some women, the lumpiness is more pronounced than for others. In most cases, this lumpiness is no cause to worry. If the lumpiness can be felt throughout the breast and feels like your other breast, it is likely just normal breast tissue.
Lumps that feel harder or different from the rest of the breast tissue (or the tissue of the other breast) or that feel like a change may be a concern. This type of lump is more likely to be breast cancer, though some benign breast conditions (such as cysts and fibroadenomas) can cause similar changes. See your health care provider if you:
If you are unsure whether you should have a lump checked, it is best to see your provider. Although a lump may be nothing to worry about, you will have the peace of mind it has been checked.

Liquid leaking from your nipple (nipple discharge) can be troubling, but it is rarely a sign of breast cancer. Discharge can be your body's natural reaction when the nipple is squeezed. However, the following may be signs of a more serious condition, such as breast cancer:
Nipple discharge can also be caused by an infection or other condition that needs medical treatment. For these reasons, if you have any nipple discharge, see your health care provider.
Breast self-exam seemed promising when it was first introduced. However, studies on its effectiveness at finding breast cancer early and improving survival showed it did not offer the benefits of other screening tests .
A meta-analysis combined results from the two largest randomized controlled trials on breast self-exam to date (one in Shanghai, China and one in Russia) . The Shanghai study included about 266,000 women and the Russia study included about 122,000 women. The combined analysis found no difference in rates of breast cancer death after 15 years between women who did routine breast self-exam and those who did not . And, the breast self-exam groups had more false positive results, leading to nearly twice as many biopsies with benign (not cancer) results as the other groups .
Figure 3.1 lists the breast cancer screening recommendations of some major health organizations.
Breast self-awareness includes knowing your risk, getting screening, knowing what is normal for you and making healthy lifestyle choices. These messages can be used to increase awareness and empower people to take action and make informed choices about their health.
