Did Joe Biden really have stage 4 cancer, or was it a political cover?

In the final days of his term , Joe Biden was diagnosed with stage 4 cancer. I never could understand how somebody with access to the best healthcare on Earth did not get diagnosed before it got to Stage 4.

Could it be that since Biden forgot to pardon himself while he was handing out blanket pardons to everyone who could be sent to prison for things that they did while Biden was president. He forgot to pardon himself so the DOJ could investigate him and his son's involvement in influence peddling. He could be sen to prison while his son walks free.

I think that he cooked up this scheme because he wanted the DOJ to think that if he was prosecuted for his crimes he would be dead before the end of the trial.
