If it's not one thing, it's another. My newest fear is breast cancer. I am only 28 years old and have never had children. But I have been having some dull pains in my left breast. When I feel around, I don't think I feel any lumps. But honestly, I don't know what I am feeling for! I know there are lots of lymph nodes in your breast and they will sometimes get inflamed. I am so tired of the worries! Can anyone help me??
