I have Crohn's, which means I have a higher chance of getting certain kinds of cancer in my digestive system.

I also have Ankylosing Spondylitis, for which I need to take immune suppressive medications to slow my spine's deformation and my body growing bone where it's not supposed to be, and these make me more likely to catch viral infections. My medication is a TNF blocker, which also increases my chances of other cancers like skin cancer and hepatosplenic T-cell lymphoma (HSTCL).

Basically, no, a busted immune system doesn't give superpowers. It just tosses more wrenches in the works.
