I have been experiencing unilateral left sided itching concentrated under my left Breast for the last two months. Just in the last few days I have noticed that my veins are visible on that breast but not on other. The itching is intermitant as is feeling of heightened sensitivity not associated with my cycle. There feels to be a thickening of the skin but no dimpling or rash per say. I am 45 with a paternal grandmother who died in her 40 s of breast cancer. I have been tested and am negative for the BRAC gene. I have an apt for yearly exam and mammogram (my last was two years ago) on the 17th. Nervous to wait, would appreciate your thoughts.
