Hi, I found a lump about the size of a dime about 6 months ago in my armpit. I can hardly feel it and can barely see it, but it is there. It only hurts if I touch it and that just recently started. My grandmother, her sister (my great-aunt), and their mother (my great-grandmother) all had breast cancer so that is the only reason why I am worried. I am 36 yrs. old, overweight, and out of shape, but no other physical problems. Could anyone tell me if there is a chance I could have breast cancer? I think if I did I surely would have other symptoms by now, so I don't think I do but I am worried a little. Thank you.
