Every woman should get used to the texture and appearance of her own breasts. Breasts form during puberty and keep changing throughout a woman's reproductive life. Breast undergoes physiological change with every period, pregnancy and during breast feeding. With menopause most of the milk producing tissue disappears and gets replaced by fat.
Personal breast awareness and routine screening is the key to early detection of any possible problems.
It is a good idea to look at your breasts in the mirror at least once a month after periods. Before periods it is very common for most women to experience some breast tenderness, lumpiness and discomfort. Checking at this time could cause anxiety as it is tender, uncomfortable and lumpy. Therefore, Breast self-examination should be practiced once a month after periods. In women who do not menstruate, any day on a regular basis is sufficient.
Don’t look for trouble. Know what is normal. If normal is known, then trouble becomes easy to spot.
When you are familiar with what is normal then a change is easy to spot.
When you are familiar with the way your breasts look and feel normally, then a change is perceived easily. It is better not to do a self- examination looking for problems as they are described in most other portals ( ie) look for lumps, skin changes or discharge. When you keep looking for trouble, everything seems like trouble. So my advice is to know what is normal, then if there is an abnormality then it is perceived easily.
