Hi, Thanks for posting your query. I am happy to address your questions. Generalized breast lumpiness usually feels like lots of little bumps (nodularity) or as though some areas of the breast are thicker or denser than other areas. Your breasts also may feel tender. The lumps may occur in both breasts around the nipple and in the upper, outer part of the breasts, especially before your menstrual period. The lumps may come and go and change size in just a few days. Generalized lumpiness was once thought to be abnormal and was even called fibrocystic breast disease, but it is so common that it is now considered normal. Tamoxifen, a synthetic antiestrogen, relieves pain, but should be evaluated every 3 months while taking tamoxifen to monitor for irregular menstrual bleeding. The relapse rate is as high as 39% to 48% after tamoxifen is stopped. Estrogen-progesterone combinations have been shown to alleviate breast nodularity associated with breast pain in 70% to 90% of women. Medroxyprogesterone improved these symptoms in 85% of women. Hope I have answered your query. If you have any further questions, I will be happy to help. Thanks
