###Human: Is it usual for fibroadenoma of the breast to pain during the fertile days? ###Assistant: Hi, I have gone through your narration of symptoms. With the history of pain occuring around the periods time, it is more likely to be Fibroadenosis rather than Fibriadenoma.. I would like to assure you not worry about either of this conditions as both of them are only benign conditions and not cancerous.. It wont cause any dangerous harm.. There is nothing much specific help we could get drastically from diet modification for this condition.. Just maintain your ideal body weight.. But still you need to confirm it by a Biopsy.. Need not fear about biopsy.. As you described it is not removal of part of the lump.. It is just a pinch of the lump, a small bit from it with a small injection.. Sometimes your surgeon might decide to excise it as a whole and send for biopsy in which case, it is called Excision biopsy.. But that will serve you dually for diagnosis and also completion of treatment by total removal.. And it is only a minor surgery, not a major one.. So, just throw away your fears on that.. You can continue breastfeeding and plan for pregnancy. But I think, the lump may increase in size during pregnancy which I am not sure about.. You need to consult with a Gynaecologist rwgarding this.. Do the investigations as adviced below and review back CBC, RBS, SERUM LIPID PROFILE, FREE T4, TSH, USG BOTH BREASTS
