If you need some sort of medical treatment then seriously look at going to other countries to get it treated. you would be surprised how much affordable it is and how good the care is compared to the US. Ecuador, Chile, Philippines, Thailand all have excellent medical staff, many Dr's trained in the US too. Just the cost is much much lower.
Overall the best thing you can do for your health is drink lots of water and eat plenty of organic vegies that you preferable grow yourself. You body can heal itself of many things but it needs water and nutrients to do it. Long fast will also help the body to heal. Lots of info out there on the subject.

I'm skipping o care and I hope everyone else does too.
