There are other subtle findings that you look for, such as calcification, which may be associated with this area. Development of asymmetry may be a sign of something changing within the breast tissue. Sometimes this can represent early changes towards cancer. Comparison to any previous exams would be of great help. Asymmetry should be monitored closely and sometimes biopsied if it raises any level of suspicion.
Most people find that while in the shower, breast exams are easily done.
While your skin is wet, it is easy to move your hand across the breast to do an exam or you may take the option of lying down to do your exam. In either position, the hand on the side to be examined should be stretched above the head. The other hand should examine the breast beginning on the outside going from top to bottom and back to the top again and working your way toward the inside. Also check under your arms for any swollen areas and squeeze your nipples for any discharge. This should be done one week after your menstrual cycle and should be done on a monthly basis.
