Paget’s disease of the nipple, which is also called the mammary Paget’s disease, is an uncommon form of breast cancer that starts from the nipple and expands to the dark circle of skin called areola around the nipple.
The exact cause of this disease is unknown. However, theory suggests that this type of cancer results from underlying ductal breast cancer and develops independently in the nipple.
Additional factors that contribute to developing breast cancer:
- Age (the average is 57)
- History of breast cancer
- Family history of breast cancer
- Overweight
- Drink a lot of alcohol
