...from the attached article...and as posted earlier...
--------------------
PSA levels may not have been checked

One screening test for prostate cancer involves a blood test that measures the level of prostate-specific antigens, which are proteins made by cells in the prostate gland.

Although there is no cutoff level that clearly indicates the presence of cancer, many doctors use a cutoff of 4 nanograms per milliliter to recommend further tests with a urologist, according to the American Cancer Society.

For an advanced form of cancer like Biden's, a recent PSA test would have likely shown elevated levels.

However, the U.S. Preventive Services Task Force recommends against PSA-based screening for men age 70 and older due to harms such as false positives leading to more tests or a diagnosis of problems that would not have caused symptoms or death.
