On Tuesday, I took a “tracer” dose of radioactive iodine. On Wednesday, I took another. Thursday I underwent two scans to see where the tracer doses went. As expected and hoped, the scans showed that the radiation was pretty much confined to my remaining thyroid tissue.
Based on the result of those scans, the doctor set my “big” dose of radioactive iodine to 75 millicuries. In terms of the range of potential doses used to treat thyroid cancer, it’s in the lowest range of doses.
On Friday morning, I took a 76 millicurie dose of radioactive iodine. Apparently, I also contracted a cold and cough. Since the radiation, lack of thyroid hormone (part of the treatment), and restrictive diet most likely reduced the overall effectiveness of my immune system, I now have a sinus and chest cold on top of the symptoms of hypothyroidism and radiation treatment. I’m sneezing and coughing on a pretty regular basis, and feeling exhausted and tired much of the rest of the time.
I know this is nothing compared to what other cancer patients like my mother (who died earlier this year from melanoma) have gone through, and I am both respectful of that and grateful that my situation isn’t worse than it is. Still, it’s not an exaggeration to say that I feel worse than I can remember feeling in a long, long time… if not the worst ever. While I will probably never understand what my mother went through in her final days, I think I have a greater appreciation of it than I ever did before.
Tomorrow morning, I look forward to being off the low-iodine diet. That means I can have things with dairy (like my morning coffee with milk), sandwiches with cheese, and pizza again. I can have sushi, Chinese food, Indian food, and more. Perhaps even better than that, I’ll once again be back on the synthetic thyroid hormone. That should be the end of the severely dry skin, muscle weakness, unexplained muscle cramps, shortness of breath, and other symptoms I’ve had to endure since before Thanksgiving.
This coming Friday (12/26) is another set of scans for radiation, to determine where the last “big” dose went. Friday’s scan is supposed to be “more revealing” in some way than the one I had last Thursday.
After that, I’ll be working with the endocrinologist to regulate the dose of synthroid I’ll be taking from now on to give me a “normal” level of thyroid hormone in my blood. I guess you could say that the end is in sight, at least as much as there is an end to this. I’ll be having tests each year from now to confirm that the cancer hasn’t returned, so in a sense it will never be truly “behind me” and will always be somewhere out there in the distance.
