Wow, that is quite rough. :-(
In my case it wasn't so bad. Thankfully, the thyroid cancer I had (even
though it had managed to metastasize into my lungs and ribcage already)
seems to have responded to the radioactive Iodine-131 therapy and thyroid
lobe removal surgery (neck had to be cut open again one month later after
right lobe was removed & biopsied and found to be positive) I had to endure
(I was apparently iodine avid). The only negatives about having thyroid
cancers is that they are unusually tenacious (you think you are cured from
them (clear gamma camera body scans, no thyroid gland anymore) and in one to
20 years later some thyroid gland cells that managed to escape into the body
somewhere can spontaneously start to regenerate themselves again.
Plus, another negative to having advanced thyroid cancer is they like to
keep your TSH (thyroid stimulating hormone (that your pituitary gland puts
out)) suppressed with levothyroxine (synthetic T-4 thyroid hormone). Only
problem with that is that some people (apparently I am one of them) don't
respond well to being highly suppressed like that.
Not a smoker either (used to dip Copenhagen snuff), but they say that
probably doesn't have anything to do with developing it. Not to belittle
the ordeal you had to endure, I could only wish that my cancer issues were
due to sexual indiscretions (all the suck of having cancer, with none of the
fun ;-) ).
