Hi, I had gone through your question and understand your concerns. Microcalcifications are nonspecific sign and may indicate both benign and malignant lesions. Linear cluster may be worrying sign but still there more chances of being benign. but of course, it should be ruled out completely by doing MRI scan or ultrasound guided biopsy. This would show us exact pathological finding. Microcalcifications , as I said, may be precancerous in some cases but if these are present for longer period then these are probably just related to fibroids or adenomas which are benign changes. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
