Info. please...Does anyone know how colloid carcinoma's start? Someone just had a lump removed. It was, however, surrounded by smaller cysts filled with fluid that weren't on the mammogram two years previous. Could those harbor cancer cells waiting to divide and become tumors? Would it be better now to have complete radiation on that side to be sure instead of a localized dose via a mammostat (tube) directly into the hole where the tumor was taken out? Decisions need to be made quickly. There are also spots of calcium on the other side that look like just calcium but might be biopsied. Hard to know the best course...Please respond to: [email protected]
