Hi, I'm just looking for a little advice. I had a lump on my right breast that my doctor thought was a lymphoma. You can actually see it on the breast, this was in February. Yesterday I noticed a dull ache in the same breast when I was checking for changes. In the same breast this morning it really hurts when I press on that area above the lymphoma. I'm talking about I jumped when I touched it as it was so sore. Today though the area feels which I can only describe as hollow under the skin. I trust my doctor implicitly and trust that it's a lymphoma. The area around the lymphoma and the lymphoma itself hasn't got any bigger. I don't think it's cancer but I have no clue as to what it is, maybe a cyst perhaps. Anyone any ideas? I
