In 1990, I had a mammogram and an ultrasound done locally after discovering a lump. Nothing showed up on either and the physician said not to worry about it and come back in a year. I assumed he knew what he was talking about. In less than a year the lump grew much larger so I had another mammogram and ultrasound done in Raleigh, which led to a biopsy, which led to a diagnosis of breast cancer, stage II. In hindsight, I should have insisted on a biopsy at the first sign of the lump. If I had gone on physicians advice I would be dead now. Be your own best friend and insist on a biopsy. If it turns out negative, then nothing lost, but . . . It's your life and you have to take control. Don't let any physician talk you out of tests if you want them.
