Had one for about 5 years now, other than some minor discoloration on the bottom, works like new.

That's not what it's saying. The major major damage cancer does is the drugs we use to kill the tumors kills lots of regular tissue. It's a game of try to kill the tumors before we kill the host. The main reason why we have to use chemotherapy is to stop the cells that are metastasizing so they don't land and grow somewhere else. If you stop that mechanism, they will still grow, but something like skin cancer you can just continually cutout and target to that specific area, which not only would keep the patient from going through chemo, but also not hitting some vital organ somewhere and grow on that.

This would be huge if they could stop metastasizing because cancer would then be more like a benign tumor now and be so much less deadly.

Worse it'll give you just enough upvotes to basically be irrelevant. You won't be banned, that would raise a red flag, but if you're just given a couple dozen upvotes and forgotten your post will vanish into the noise.

At least that's what I would do
