While I131 is not invasive and does not come with side effects like chemo, it isn’t completely without risks. So, let’s talk about them.
1) It doesn’t work. We go to Kansas, finish all the testing, go through the isolation period, repeat the CT in 8 weeks, and everything looks the same. This is a very real possibility.
2) It works too well. The attack on the lung metastasis triggers an inflammatory response and respiratory distress, while he is stuck in isolation and the veterinary team is unable to intervene. Because I’ve decided to not stop steroids (thus potentially making treatment less effective) this is not something I’m worrying about too much.
3) His thyroid is rendered non-functional. Hypothyroidism is a possibility I’ve prepared for, and just means he will need to take medication for it daily for life. A small price to pay.
