it depends on the drugs required and some are extremely expensive ...that would be $250,000 dollars ...again it depends on the cancer you have as it varies considerably .
outpatient covers cancer. Most of cancer treatments are outpatient not inpatient ie : chemo , scans , etc the only inpatient would be surgery and typically the most expensive part is chemo where just 1 round can run $250,000 + depending the drug
it depends on the amount the US taxes you as Thailand's tax schedule may be higher
Say you pay 20% in the US and Thailand is 30 % than you will be possibly be responsible for the difference of 10% to Thailand onto of the 20% to the US ...Just depends on how much you make
What I love is just how many DTV holders will waste 5 prime working years or more ,in Thailand , making next to nothing then later in life regret it because everyone else landed a decent career back home and contributed to a pension or better yet recieved a company pension and they will end up broke because they wasted their prime years .
The streets of Thailand are going to have lots of begging foreigners in it's future and no way to get home
