“Very Rare” cancer.

Maybe not so rare now.

[Pontiac]

"With the cancer that Bryan has, which is a very rare form of cancer, the CAR-T treatment had the highest chance of success as the cells are reprogrammed to fight this cancer that is within Bryan. His cells did re-infuse themselves, and did in fact start reproducing within his bone marrow.

"At first, the mass did start to shrink, but then the cancer started fighting back."

At first the treatment worked and then the cancer came back with a vengeance.

Spike protean?

Nah!

That would be conspiracy theory non-sense.
