Everyone, including the ultrasound person said this lump in my armpit was nothing even after I am 11 years out from a mastectomy and eight rounds of chemo. So I went to my pcp and he said, This is nothing but I pushed for an ultrasound again and a mamogram on the left. This ultrasound tech went and got the radiologist he said show me and it is cancer. And now after the biopsies and CT/pet scan I am stage 4 with metastasis to my lymph nodes all over my body, my bones, and several in both lobes of my liver. Just insist on the biopsy. For all your lumps. Don’t wait this disease move so quickly. I had my first ultrasound in January and my last one in July. Don’t wait.
