Red rash under my breast?

This morning after showering I noticed almost a rash like redness under my breast. It doesn’t itch or anything so far, the skin just seems red. I’m freaked out though because I heard breast cancer can show up as a rash. I’m 19. Has anyone else had this?

It’s a really common place to get rashes. Is it dry or bumpy? Often it’ll be either a kind of excema or thrush. If it’s not itchy then it’s possibly excema and you could use an E45 or oilatum cream on it.

I’m not a doctor though, maybe show a pharmacist or your gp if it doesn’t clear up in a few days.
