Each patient will be completely different - so one person's situation may not match anothers.
The advice the medical folk will work on is treat the medical condition with the best form of treatment first. If it is compatible with flying afterwards then all the better. It is important you have the best treatment and not the second best just because it might allow you to fly in the future.
You really need to speak to the medical staff looking after you for their advice. As it sounds like your only option you might be better looking to speak to people who aren't necessarily pilots about the positives and negatives for the op itself. Your aviation authority's medical dept will have strict guidance on what rules/procedures/protocols they have in this situation - if you haven't already - call them to discuss it.
