What is this mark on my chest?

[hairfryer]

This mark has developed from a small red spot to a bigger red patch, about 1cm with a white inner area. No pain or itching, I’ve had it about a week. Any ideas? Not sure if I need to get it checked.

Looks like ringworm? Although that's usually a bit itchy.

Pop into a pharmacy and ask for their advice

Could be ringworm or maybe a herald patch for pityriasis rosea

Pityriasis rosea. This is a herald patch. It'll go away on its own.

looks like ringworm

Thanks all. I thought because it wasn’t itchy it couldn’t be ringworm but seems it might be. I have t1 diabetes so perhaps a bit more prone to it, I’ll try some antifungal cream.

Could it be Granulaoma Annulare - I have been recently diagnosed with it and this is how it started. It is much bigger now - doesn't hurt or itch.
