I wonder sometimes why these cancer statistics are exaggerated and wrong.  I had family members who had breast cancer.  Yes fibrous tissue is an issue.  But the only real issue is genetics.  Breast size is not a factor. Gender is not a factor. When a male gets a breast tumor the doctors actually make the breast tissue grow so the cancer can be removed easier.  So if you have cancer in the family have a genetic screening and then a biopsy, I did.
