Prostate cancers are graded for aggressiveness using what’s known as a Gleason score. The scores range from 6 to 10, with 8, 9 and 10 prostate cancers behaving more aggressively. Biden’s office said his score was 9, suggesting his cancer is among the most aggressive.

In February 2023, Biden had a skin lesion removed from his chest that was a basal cell carcinoma, a common form of skin cancer. And in November 2021, he had a polyp removed from his colon that was a benign, but potentially pre-cancerous lesion.

Slow prostate cancer is much more common (and often not treated because the patient is estimated to die from old age before the cancer gets bad). Obviously not the kind of cancer Biden has.

I would argue that both Biden and Trump have brains that aren't fit to be president.
