I just found a lump on my left breast. It was not there last month. There are two almost connected together, pea size, hard, no pain. Where they are located, the breast feels heavy, like there is lead. I am very thin due to my celiac disease, so you can see these lumps. I am on birth control for my endometriosis and had surgery March 2011 for +HPV and Grade 2 lesion in the cervical region. I guess always the first concern is Breast cancer. Is it likely that this can be a cyst. I do have a Gyn appt in 2 wks to obtain my second ( dr wants me to have 3 total before going yearly, now every 6months) pap and HPV test since my surgery in March 2011.
