Ian,
I was astonished to read your post about possible breast cancer. It does happen. My Father In Law is a breast cancer survivor and so is my Mother in Law. My FIL had his left breast removed in '97 and then my MIL had a lumpectomy last year. Thank goodness for advancement in the treatment of this disease.
I pray that it is NOT cancer, but if it is- there is HOPE!
You will be in my prayers!
Tanya
