Hi! Not to scare you,but my mother's mammogram showed a little something each time. But,no doctor was concerned till her left hand swelled. Shortly after, her left breast turned red and swelled the flag raised. Well,after 1 year of many doctors and tests. We found out that it's Stage 4 breast cancer that has spread all of her left side, chest, neck and bones (spine). And now that she also has a tumor(canerous) in her brain near her optic nerve. All I can say is, talk to your doctor if he won't do anything,find one who will !!! My mom's 75 and was fairly healthy(expect aches&pains)till now. Now she's full of Cancer!!!! SO PLEASE GET IT CHECKED OUT!!! Take Care.
