I have great empathy for what you're facing. I've lost family members to cancer. It is a very unique form of helplessness in face of calamity. That said, I'm working for a genomics company, part of our mission is to understand each cancer as a unique disease so we can diagnose it correctly, leading to personalized treatment. In my personal opinion IDEs are not the rate-limiting step to curing cancer, and a better one won't meaningfully contribute. This doesn't mean what you're doing is not meaningful though!
