Breast self-examination

According to a meta-analysis in the Cochrane Collaboration, two large trials in Russia and Shanghai found no beneficial effects of screening by breast self-examination "but do suggest increased harm in terms of increased numbers of benign lesions identified and an increased number of biopsies performed". They concluded, "At present, screening by breast self-examination or physical examination cannot be recommended." Although breast self-examination increases the number of biopsies performed on women, it does not reduce mortality from breast cancer. In a large clinical trial involving more than 260,000 female Chinese factory workers, half were carefully taught by nurses at their factories to perform monthly breast self-exam, and the other half were not. The women taught self-exam detected more benign (normal or harmless lumps) or early-stage breast disease, but equal numbers of women died from breast cancer in each group. Because breast self-exam is not proven to save lives, it is no longer routinely recommended by health authorities for general use. It may be appropriate in women who have a particularly high risk of developing breast cancer. Some charitable organizations still promote BSE as a universal screening approach, even in the low-risk women who are most likely to be harmed by unnecessary follow-up procedures. Writer Gayle A. Sulik, in her book Pink Ribbon Blues, suggests that these charities are motivated by their donations depending on fear of breast cancer. Among women with high-risk BRCA mutations, about 10% said that performing breast self-examination increased their anxiety. Half of those who did perform BSE felt that it gave them a sense of control. Learning breast self-examination increases a woman's level of depression, worrying, and anxiety about breast cancer. ==Methods==

A variety of methods and patterns are used in breast self-exams. Most methods suggest that the woman stand in front of a mirror with the torso exposed to view. She looks in the mirror for visual signs of dimpling, swelling, or redness on or near the breasts. This is usually repeated in several positions, such as while having hands on the hips, and then again with arms held overhead. The woman then palpates her breasts with the pads of her fingers to feel for lumps (either superficial or deeper in tissue) or soreness. There are several common patterns, which are designed to ensure complete coverage. The vertical strip pattern involves moving the fingers up and down over the breast. The pie-wedge pattern starts at the nipple and moves outward. The circular pattern involves moving the fingers in concentric circles from the nipple outward. Some guidelines suggest mentally dividing the breast into four quadrants and checking each quadrant separately. The palpation process covers the entire breast, including the "axillary tail" of each breast that extends toward the axilla (armpit). This is usually done once while standing in front of the mirror and again while lying down. Finally, women that are not breastfeeding gently squeeze each nipple to check for any discharge. Various mnemonic devices are used as teaching devices. One is called the ''seven P's of BSE, after seven steps that are named to have the same first initial: Positions, Perimeter, Palpation, Pressure, Pattern, Practice, and Planning'' what to do if a change is found in the breast tissue. For pre-menopausal women, most methods suggest that the self-exam be performed at the same stage of the woman's menstrual cycle, because the normal hormone fluctuations can cause changes in the breasts. The most commonly recommended time is just after the end of menstruation, because the breasts are least likely to be swollen and tender at this time. Women who are postmenopausal or have irregular cycles might do a self-exam once a month regardless of their menstrual cycle. Teaching correctly performed breast self-examinations normally takes a trained professional seven to ten minutes.{{cite journal ==Recommendations==

The World Health Organization, the Canadian Task Force on Preventive Health Care, and many other scientific organizations recommend against the use of breast self-examinations. Also, the Royal Australian College of General Practitioners states that teaching women to perform breast self-examination is no longer recommended. In the US, however, there is no consensus among organizations related to breast self-examination as the American College of Obstetrics and Gynecology, and the American Medical Association recommend monthly breast self-examination while the American Cancer Society, the National Cancer Institute, the US Preventative Services Task Force, and the National Comprehensive Cancer Network neither recommend nor discourage breast self-examination. , breast self examination was being investigated as to its usefulness as an alternative screening technique in remote areas where women do not have access to regular mammogram tests or comprehensive gynecological care, but more research is required to form a consensus. ==History==

Activists began promoting breast self-examination in the 1930s because their exhortation to not delay seeking treatment for suspicious lumps was not affecting the death rate. In the 1970s, researchers began to report that women were being told to do this even though there had never been any evidence to suggest that it saved lives.{{cite book ==See also==
