Rare benign tumours of the breast

The following are rare benign breast tumours. They do not increase the risk of developing breast cancer. The primary treatment for these types of benign breast tumours is surgical removal.

Lipoma

Lipomas are benign tumours made up of fatty tissue. They can occur anywhere in the body, including the breast. Most lipomas are small (less than 1 cm in size), single lumps that grow very slowly.

Hemangioma

A hemangioma is a tumour made up of a mass or lump of blood vessels. They are rarely found in the breast. These are small tumours, usually less than 2 cm in size.

Hamartoma

Hamartomas are tumours caused by an overgrowth of tissues normally found in the area where the tumour starts. They are rarely found in the breast.

Other rare benign tumours

  • adenoma
  • neurofibroma
  • granular cell tumours
