如果活检确定是纤维腺瘤(fibroadenomas),是不需要马上切除的,因为切了很可能还会长.但需要定期检查.除非：影响外观了；痛；本人太担心；有家人得过乳腺癌；活检病理结果不确定；或只是想一劳永逸.

Treatment
Many doctors recommend removing fibroadenomas, especially if they keep growing or if they change the shape of the breast. Sometimes (especially in middle-aged or elderly women) these tumors stop growing or even shrink on their own, without any treatment. In this case, as long as the doctors are certain the masses are really fibroadenomas and not breast cancer, they may be left in place and watched to be sure they don’t grow. This approach is useful for women with many fibroadenomas that are not growing. In such cases, removing them all might mean removing a lot of nearby normal breast tissue, causing scarring that would change the shape and texture of the breast. This could also make future physical exams and mammograms harder to interpret.
It’s important for women who have fibroadenomas have breast exams regularly to make sure they are not growing.
Sometimes one or more new fibroadenomas grow after one is removed. This means that another fibroadenoma has formed – it does not mean that the old one has come back.
