Calcifications found on mammogram

Hi, I'm new here!
I had a mammogram on Thursday and they have found a cluster of micro calcifications. I'm now waiting for an appt. for a biopsy. I can't help but worry. In the last month I've been poorly twice, I had shingles then about a week later I ended up in hospital with a urine/kidney infection. Plus I get tired very easily and suffer from headaches a lot. Could this all be linked to me possibly having breast cancer? I'm thinking is that why my immune system is low? Plus about 10yrs ago I had a hysterectomy because I had severe abnormal smears which turned out to be precancerous cells. My minds working overtime as you can probably tell. How worried should I be?

Take a deep breath....calcifications are not uncommon. I am a breast cancer survivor and I know how scary all this is. Until you get the biopsy and know for sure if you are facing a problem, don't drive yourself crazy...stress is bad for your immune system. It sounds like you have had more than your share but be as positive as you can. There is an excellent cancer support site www.whatnext.com if you want additional information. I will be thinking good thoughts for you!
