What is the Relationship Between Fibroadenoma and Breast Cancer?


For all practical purposes, there is no significant relationship between a “true” fibroadenoma and breast cancer.

However, there is slight overlap in the mammographic and sonographic appearance of some fibroadenomas and some uncommon forms of breast cancer. For this reason, care should be taken when attempting to make the diagnosis of a breast fibroadenoma without a biopsy.

Usually this means if biopsy is not performed, at a minimum the potential “fibroadenoma” should be followed over an extended period of time (usually a minimum of two years) to be sure it’s not a slow growing breast cancer masquerading as a “fibroadenoma.”

Also, even if a biopsy is performed, there is some overlap between a fibroadenoma and other tumors. Fibroadenomas belong to a class of tumors in the breast known as fibroepithelial lesions. Rarely (exceedingly rare), the tissue obtained from the tumor during the biopsy can be difficult to differentiate from a “relative” of the fibroadenomas in the same class of tumors known as a Phyllodes tumor (of which a small percent can be malignant).

For this reason, even after a biopsy, at least one follow up visit may still be indicated for a fibroadenoma diagnosed by biopsy, but it’s usually just due to an over abundance of caution because no-one wants to miss a sneaky form of breast cancer.

About Ryan Polselli

Ryan Polselli designed MammoLink® to send a portion of every mammogram back to the community to the charity chosen by each patient. "Our current healthcare system forces patients to jump through an endless number of hoops to take care of themselves. It would be hard to design a more inconsiderate, inconvenient, and inefficient system. The system "bends" patients, often unreasonably, to fit the needs of the system, rather than "bending" to the needs of the patient. It is time that we completely redesign a healthcare system that puts patients first and gives patients complete control so that they can best take care of their health. This is especially true in the field of breast cancer screening and diagnosis." --Ryan Polselli, M.D., Diplomate of the American Board of Radiology, Fellowship Trained Breast Imaging Radiologist, Founder and CEO of MammoLink®
