The cancer that grows from breast tissue is called as Breast cancer. Signs of breast cancer may comprise a lump in the breast, dimpling of the skin, fluid coming from the nipple, an alteration in breast shape, or a red scaly patch of skin. In those with distant spread of the disease, there may be inflated lymph nodes, bone pain, shortness of breath, or yellow skin. Risk factors comprises being female, lack of physical exercise, obesity, hormone replacement therapy during menopause, consuming alcohol, ionizing radiation, early age at first menstruation, older age, having children late or not at all, and family history. Counting BRCA1 and BRCA2 among others, about 5–10% of cases are due to genes inherited from a person's parents.
