I had a mammo 2 years ago because of slight pain on left side of left breast. No lumps. Mammo was normal . Pain went away. I am having another mammo end of Feb. because I am due but also because I have pain again. This time pain is worse. Feels achy, sharp stabbing in left breast, comes + goes but feel it on a daily basis. Also getting pain on left side and upper left back. My Dr. couldn't feel any lumps but I am aware that mammo can find what Dr.can't feel. Breast aren't swollen, no redness,no heat,no rash,no orange peel,no dimplimp,so far no discharge. I have a tendency to overreact thinking I have every disease know to man but this time I am truly scared because it's my breast. Can you have breast cancer with pain as only symptom. Is it possible that I have breast cancer and the pain means that it is spreading, even though I can't feel a lump. My Dr. says that since I have had some pain that first started 2 years ago she says that sheshe would expect to feel a lump at this point. I am 44 years old with 2 daughters, youngest is only 4, and I want to see her grow up. So scared it's all I can think about. Please help.
