Can a benign breast nodule turn into a malignant one?
That depends on if it is called benign by imaging or biopsy. If biopsied, it still depends on what the "benign" tissue is called by the pathologist, and how much tissue was sampled. So to answer your question, any abnormal area in the breast should continue to be followed by a qualified practitioner until it is definitely benign. For example a lump that is removed and found to be a fibroadenoma, is benign and does not become malignant. On the other hand, a vague nodule on mammogram thought to be benign, may turn out to be malignant with further investigation.
