Giant Mammary Hamartoma is a rare mass that forms in the breast that is not cancerous. The mass is made up of fatty and fibrous tissue. Even though the tumor does not produce cancerous cells, this tumor may become large, resulting in uneven breasts. These hamartomas are usually found by accident on routine imaging or on a physical exam of the breast. There are usually no symptoms but if the mass is large enough, it could cause discomfort, uneven breasts, and swelling. It is important to fully investigate these masses through biopsy because a coincidental cancer could be growing next to it that was not seen on imaging. Often times, people will remove the mass for cosmetic reasons due to assymetry or if the mass is causing pain and swelling.
If you have been diagnosed with giant mammary hamartoma, talk with your doctor about the most current treatment options. Support groups are also good resources of support and information.
