Itchy breast

[Bonkerz]

So this unsightly mark appeared on my breast about 2 weeks ago. It got big and red so I asked a nurse friend to look at it. She said it looked like an ulcer and to cover it which I've been doing.
It's gone down but I think I've reacted to the plasters I've been using it it's spread. Boobs are really itchy too.
Tried to get docs appointment but nothing till August!
Any ideas how I can home care this????
First pic was 2 weeks ago
2nd pic is tonight.

I’d get an emergency appointment for that, especially if it’s growing.

I would phone again and get an urgent appointment. Maybe it can wait til august but if it was me I would not be taking that risk.
