Not OP, but cancer isn’t a disease as much as it is an inevitable breakdown of our body processes in various ways, which manifest as different kinds of cancer.

Not OP, but cancer isn’t a disease as much as it is an inevitable breakdown of our body processes in various ways, which manifest as different kinds of cancer. Our cells need to divide and make new cells, and it isn’t a perfect process. We have natural mechanisms to prevent or destroy any cell that divides wrong, but it’s a numbers game. We have 30 trillion cells in our body, and after a quintrillion divisions something is going to go wrong in a way that becomes cancerous. To be able to “cure” that would mean the ability to understand and manipulate the human body in such precise ways it would almost certainly also allow us to fix/cure/manipulate any body process, including aging.
