If it is early, it is very treatable and Patrick can be fairly normal, however there will most likely be some surgeries. My school did a thyroid cancer benefit for a player at our biggest rival. I didn't read the article, but this girl was able to do everything until it was time to prep for surgery. It is very treatable, especially if it is isolated to his thyroid at this point. Worst case if that is indeed the situation, he can have it removed and be okay with additional supplements.
It sucks to know this because it means that you have been touched by the disease.
The girl we did the benefit for is in her second year of college and is in good health. She was diagnosed with Stage 3 IIRC and fought it after six or seven surgeries because it got in her lymph system.
Sorry to ramble a bit, but I was close to a situation.
