I have one week left of my rads, everything was going really well. Until virtually overnight a small lump came up. It was tender and painful. In the same breast as the cancer. They think it is a cyst. But they aren’t totally sure and took some fluid, but not a lot. They also did a biopsy. Does anyone else have a similiar story? Must admit, feeling like I have been kicked in the teeth as the end was in sight…
