Different types of breast cancer can affect men in the same way that they can women. The most common type of breast cancer to affect men is called invasive ductal carcinoma, which is also the most common type in women. Other rarer types are inflammatory breast cancer, Paget’s disease of the breast, and a pre-cancerous condition known as ductal carcinoma in situ (DCIS).

The most common symptom is a lump in the breast area. However, other signs may occur such as a change in the size or shape of the breast, an ulcer on the skin, nipple discharge, or turning-in of the nipple (inversion). Another possible symptom is a rash on the nipple or surrounding area.
