My wife has had two lumps found since she stopped treatment 2 years ago. One turned out to be scar tissue, the other an oil cyst caused by the radiotherapy. Her cancer was in the left breast, and in her nodes. Some calcification was found in her right breast last year, they operated to remove it, and that too came back fine.

No doubt about it, cancer simply doesn't go away after treatment, it remains with you for life and its entire aura hangs around you like a bad smell. There's always something waiting to appear to throw you off now and then. But luckily, not everything means the cancer has returned.

Yes it does seem to be never ending doesn’t it. Fingers crossed for something benign here. I’m glad your wife is doing ok even with the stress of lumps being found
