First of all,no one knows exactly what causes breast cancer,but many risk factors can increase both male and female chances of developing breast cancer.Doctors estimate that only 5 to 10 percent of breast cancers are linked to gene mutations passed through generations of a family.Some risk factors have a greater impact than others, and the risk for breast cancer can change over time from aging or poor lifestyle,such as smoking,drinking and diet.Also hormones seem to play a role in many cases of breast cancer, but just how this happens is not fully understood.
However,a great majority of women who have breast cancer,don't have any family history of breast cancer or follow any particular diet or healthy lifestyle.
So it's very important for all women to perform regular breast self-examinations and visit their doctor regularly for a physical examinations. Knowing the normal shape and feel of our own breasts is very important, especially when performing BSE (Breast Self Examinations) to detect any unusual changes,such as a breast lump or thickening that feels different from the surrounding tissue,bloody discharge from the nipple,change in the size or shape of a breast,dimpling or inverted nipple.
