(I know this is a little farfetched but please just explains the logistics of how he'd go about doing this) . Imagine a key medical researcher discovers he has a terminal lung cancer. He knows the operation and treatments necessary to save himself because he's a genius and an expert in the field of lung cancer. (I know it's far fetched - please just ignore that and imagine it was true). However the treatments haven't been legally approved (will take at least 5 years and by this time he'll probably be dead or have other cancers) and he'd need a team of physicians/doctors to perform it. SIDE NOTE: the treatment doesn't involve anyone but him (the only illegal thing is that he's doing an officially untested medical procedure). How would he go about getting this operation done (either legally or illegally)? Are there other countries that would perform it (such as countries were euthanasia is legal anyway)? Could he volunteer himself to test out the operation or would this be illegal?
