Does the presence of multiple fibrodenomas in both breasts increases future risk of breast cancer?, and do they need to be surgically removed?

No: Fibroadenomas do not suggest an elevated risk for cancer, although they are likely to require biopsy in most cases to prove that. Typically, these biopsies can be done in a minimally invasive way. To learn more about breast biopsy options, please see http://www.Conciergeradiologist.Com/breast-biopsy.Html.

Unusual: Multiple fibroadenomas in both breasts is not common. You probably mean bilateral fibrocystic disease. Anyway, both these conditions do not lead to breast cancer.
