Hi Hope this message finds you in good health. I have gone through your complaints and understand your concern. I generally see many cases like this at my clinic. and what i have found is at your age such lumps are generally simple cysts that are not as alarming until they become painful. a few cases definitely need a concern as a possibility of malignancy is there. your age is not an ideal age for malignancy to cuur. i suggest u should get an mammogram done first to find out the extent of the lump and from where it is exactly arising. consult a good surgeon and find out if the mammogram is abnormal for your age. The best way to confirm is by doing a biopsy at first,instead of doing a surgery. once you get a histopathology report confirming the diagnosis,then u can g ahead with the procedure. many lumps resolve by themselves,or by simple aspiration. if it has a risk of spreading,its better to get it removed. do not get afraid of surgery...it will eb done only when absolutely required. Nothing to worry about. I hope your question has been answered. If you have any follow-up queries,feel free to consult me anytime. Thanks,Take care,God bless.
