I was diagnosed with aggressive Non-Hodgkin's lymphoma in September 2012. I had a surgery and chemotherapy treatment. Thankfully, the treatment did help and since March 2013 I'm in complete remission. Now all that needs to be done are just regular check ups. The doctor who is looking after my case runs blood test every 3 months and performs physical examination. So far the results has been really good. But I am not convinced... The reason for that is, in my case, cancer was diagnosed very late ( Stage IV) back in 2012 and during that time my blood test results did not show any evidence of cancer.. It was not until I had noticed swelling of my abdomen. Then the scan was performed and a very big tumor was allocated. Nowadays, from time to time I start panicking cause find it difficult to rely fully on the blood test results. I asked my doctor to get the scan done for my own piece of mind, however, she refused saying that "only when you feel that something is wrong we will do the scan". So, can I insist on getting occasional scan done about once every 6 months?
