Sorry to hear about your problem but I am glad that you are seeking medical attention for the same. A fibroadenoma
is a benign lesion of the breast and is rarely associated with cancer. You should monitor the lump for a few months and if it is increasing in size, you should get it removed. Sometimes fibroadenomas subside with time.
Please consult a breast surgeon for the pain in the breasts. Usually it is due to fibroadenosis
which is caused by hormonal
imbalance and it responds well to medications.
Hope you get well soon.
