It’s my understanding that cancer stems from malfunctioning of our own cell processes, rather than from something that is viral/bacterial.

For that reason it seems wrong to think about cancer as “developing” resistances - I don’t believe that cancer is something that evolves/mutates.

Turns out I’m wrong! Cancer does undergo natir selection and develops resistance:

and they can be viral in nature, see oncogenic viruses e.g. HPV (cervical cancer)
It's true that cancer is made of human cells but it can still evolve on it's on. Evolution applies to anything that can reproduce while making small changes between generations. Cancer cells do this better than healthy ones, at least within the time scale of a single human life. In some species cancers have even evolved to become contagious and a single tumor has spread to thousands of hosts. https://en.wikipedia.org/wiki/Canine_transmissible_venereal_...
I'm kind of curious why those priors led you to this conclusion, as I can't follow it at all. I understand that you have already figured out that it is wrong, but I'd like to understand what made you arrive at the wrong conclusion in the first place.
Evolving is how it became a cancer in the first place.
