I was going for radiation treatments for cancer from September 1985 until December 1985. Before each treatment I had to get a blood test to ensure that there was enough bone marrow capacity to survive. Each treatment was 150 to 200 rads with 4 to 6 hours of vomiting afterwards. Over a few weeks I even developed the classical "conditioned response" such that I was already wretching with nausea as I entered the oncologists office.
I hope you get good news from the doctor. It's not fair to leave you hanging in suspense. The treatment was worse than the disease in my case. Surviving another 20 years has been well worth the enduring the treatment.
