 [ Symptoms ] if i found a lump in my breast had a biopsy and found it was a benign fibroadenoma how often should i have it checked  the lump seems to have grown in size slightly i plan to remove it eventually but not anytime soon [ Disease ] the key word in your question is benign  benign means non cancerous or not life threaning a fibroadenoma is a benign tumor caused by excess formation of milk producing glands in the breast it is possible for a fibroadenoma to continue getting larger as time goes on that does not mean it will suddenly turn cancerous you should ask your doctor how often to have this re checked however once a year with your mammogram is probably sufficient if you are concerned about the lump in any way a quick call to the nurse at your doctor is office might set your mind at ease hope this helps
