Is bleeding from nipple breast cancer?

Noy always.: Breast cancer can cause it. Paget's disease of the breast can have nipple bleeding. This can point to breast cancer, and the cells themselves are considered malignant. Inverted nipple and fissure of the nipple can have bleeding. Infection might cause it also.

Sometimes: Bleeding from the nipple can be related to local trauma during aggressive sexual activity, breast cancer, and polyps in the breast ducts. If you have blood coming from the nipple, it is important to see a surgeon and get it evaluated just in case it is related to cancer.

~10% of the time: Bloody nipple discharge is usually secondary to a benign tumor or chronic inflammation within the duct, with breast cancer a distant third. Any woman with bloody discharge requires breast evaluation, which will include a diagnostic mammogram+/-ultrasound, physical examination, and nipple aspiration cytology. If the results remain equivocal, a surgical biopsy (terminal duct excision) may be done.
