My dad cea has been up 5, 7, 12.1 and 17.7 after 12 cycles. This number is increasing trend. He told me he has been taking viagra for back pain. I did some google on viagra and read it can cut 50% of cancerous polyps. Also, his oncologist has order a PET scan of body and not a CT scan. My concern is the radiation.

Can a MRI scan detect better than a PET scan?

Do anyone know if viagra increase cea?
