Unfortunately I will temporarily be a bit slow to respond to your questions about thyroid cancer. Last week I had to undergo urgent repeat heart valve surgery, which ranks as one of the least enjoyable weeks of my existence. Thankfully, I've been looked after by an excellent team, and am now back home in recovery/rehab mode. I hope to be back to normal activities in about 3 months, but will not be at my best in the interim. I'll do my best to answer any thyroid-related questions as well and as quickly as I can, but please don't expect too much from me for a while.
