Skin rash/ could it be skin Mets ?

I develop red spots and rashes all the time - currently have a small one on my reconstructed breast. What I do is always give it a few days - usually I put some antibiotic cream on it - to see if it starts to fade on it's own. Usually it does and then eventually it goes away completely. I only see a dermatologist if I have a rash that doesn't resolve on it's own within two weeks or so. Every rash I've ever had on my breast has resolved.

Your BS isn't concerned. Considering that your rash is also on your neck and stomach, it's most likely a rash and nothing more. Treat It as a skin rash before you start thinking mets.

I get so many different skin rashes that I have about a dozen creams - okay, that might be exaggerating but not by much. Most are OTC but I also have a couple of older prescription creams. If it's itching then I'll start with something for itch - Benadryl or Cortizone or Gold Bond. If it's not itching, I'll try Neosporin or Polysporin. I'm in Canada (you too, right?) and we can't get Neosporin here but I buy it when I'm in the U.S.. I find that each works for me for different things, so I try one and then if it doesn't work, I try the other. For the current red mark, it's the Polysporin that seems to be working.

If you have spots on your arms too, and if the Claritin seems to be fading the red slightly, then it definitely sounds like an allergic reaction. Give it time. It's easy for us to panic any time something new develops but we have to remember that just because we've had breast cancer, we are no less likely to get all these other conditions that people get. Most often, a rash is just a rash.

Eigna, I had skin mets, but mine were very different from how yours are sounding. I hope that puts your mind at ease some, but do follow up with your doctors. Best wishes to you!
