Breast cancer is the most common cancer in women worldwide. Contrary to popular belief, only a minority of breast cancers are caused by a genetic fault (such as the BRCA gene). According to evidence and experience, almost all breast cancers (about 95%) happen without a very clear or specific reason.
A fibroadenoma is a very common, not cancerous breast condition, which often develops during the years of puberty and is the most common lump found in young women. It can usually be felt as a lump on the breast, which is well defined, soft to the touch and moves easily beneath the skin.
