I am 50 years old never had a mammogram need further testing until this year. I have very dense breast so they did another mammogram and ultra sound and found several spots just in my left breast, one was a mass near my chest wall. It was suggested that I get a second opinion and a biopsy. I went for my second opinion and the doctor said he didn't see anything at all. He said either way i will have to come back in 6 months for another mammogram but Now I am more confused than I was before the second doctor I truly don't know what to do. I am in my second year of menopause. I have a family history of breast cancer, lung cancer and colon cancer.
