I know your fear. My wife is a year out from breast cancer and during her 1st annual mammo, something was picked up in her other breast. Enough that they decided to do biopsies, and she's needing it fully removed in August. The initial biopsies came back is nothing concerning, but because of her recent history, they're wanting it all out.

After the biopsies, they're no longer duly concerned as they first were, but yeah, things have to be taken more seriously given her history.

About your lungs, infection and even past infections can show up as shadows, so as hard as it is, don't go having yourself dead and buried because an infection is far more likely. Just like that something they found in my wife was more likely to be something benign than cancerous. It doesn't stop the worry, though. It's the new normal. Things we wouldn't have batted an eyelid at this time 2 years ago now suddenly become all consuming. From simple back aches, to things being found on scans.

Thank you
