In many places you should be able to self refer at whatever cancer center you choose. Yes, I would push VERY HARD to see an oncologist and find out if you can get an appointment with one by doing a self referral. You must be your own advocate for your health. I have heard so many stories from people who were denied getting a colonoscopy because they did not fall into the standard age category. One person was in his early 30's and was told he did not need one. He threatened that if the doctor did not order one he was going to Mexico to get one. They did finally order one and he did have cancer in his colon, but luckily it was at an early stage and treatable. Keep pushing until you get in to see someone. Having cancer of any kind is enough of a reason to see an oncologist. The CT scan will not show anything if the cancer is microscopic, which is what mine was. Tell them you insist on seeing one and as long as your insurance will cover it they have no right to deny you. Wishing you the best of everything, and please keep us posted.
