Hello Yellowtv and a big welcome to Cancer Chat, 

You did well to go back to the doctor's after your chest rash flared up again and it's good that they were thorough and examined you properly. I think that even though you cannot feel this lump yourself, the fact that both the doctor and the trainee felt it in your right breast is a good reason to go and get this checked at the hospital. So I wouldn't feel bad about taking this appointment even if it was to just give you peace of mind. The fact that they referred you to get it checked proves that it is best to have this looked at so that you know once and for all whether there is something there or not. 

I hope that your appointment goes well on Saturday and that it all turns out to be nothing to worry about. Hopefully you will hear from other forum members who have been through this before and they will come and share their experience with you.

Everything tightly crossed for you! 

Best wishes,
