Angry Breast Rash!! What is this?? Please Give Advice.

August I got a raised red rash on my left breast, I got scared thinking it was inflammatory breast cancer, so I went and saw a breast cancer surgeon. She said no use hydrocortisone cream and it should go away. A few days later I got a raised welt type rash on the same breast. That too went away. A few weeks later another Rash but on my left breast this time, after hydrocortisone that went away too. Then Nov 10th I started getting another rash on my left breast. It has grown and isnt responding to hydrocortisone cream. I went back to the breast cancer surgeon and she looked at it and told me she's 99.9% sure it's not Inflammatory Breast Cancer. I begged her to do a biopsy but she wouldn't, she said I'm sending you to a Dermatologist. So I went to the dermatologist and she looked at it and said it looks like eczema and prescribed me some denose cream, which I've used twice and notice no difference, but now I feel a burning sensation. I've read that Inflammatory breast cancer is often misdiagnosed BUT....
I literally can't get anyone to do a biopsy, I'm scared to death of having Inflammatory Breast Cancer. But nobody is taking me serious, so I'm looking for other possible causes of this rash. No new foods, no new soaps etc. What could be this rash????

Please Help

That it totally disapperared and recurred,and the itching, are more an indication towards a 'contact dermatitis'. Chains, nylon innerwear, perfumes,external applications all can cause this.Do get examined again.
