Can cancer form in other parts of the breast?

When we say “breast cancer,” we usually mean cancers that form in milk ducts or lobules. Cancers can also form in other parts of your breast, but these types of cancer are less common. These can include:

• Angiosarcoma. This rare type of cancer begins in the cells that make up the lining of blood or lymph vessels.
• Phyllodes tumors. Starting in the connective tissue, phyllodes tumors are rare. They’re usually benign (noncancerous), but they can be malignant (cancerous) in some cases.
