Doctors say it’s ‘inconceivable’ that Biden’s cancer went undiagnosed for years: ‘He probably had it at the start of his presidency’

However, several medical doctors have questioned as to how Biden was diagnosed at such a late stage of the cancer since it can often be detected early with routine bloodwork.

“It is inconceivable that this was not being followed before he left the Presidency,” wrote Dr. Howard Forman.

"Gleason grade 9 would have had an elevated PSA level for some time before this diagnosis. And he must have had a PSA test numerous times before. This is odd. I wish him well and hope he has an opportunity for maximizing his quality of life," he added.

A cancer grading of Gleason 9 would mean that Biden's cancer would be classified as the most aggressive. In addition to Forman's post, other medical doctors chimed in about the diagnosis.

Dr. Steven Quay wrote on X, "Prostate cancer is the easiest cancer to diagnose when it first starts and to watch it progress to bone metastases. The PSA blood test shows the rate of cancer cell growth. For even with the most aggressive form, it is a 5-7 year journey without treatment before it becomes metastatic."

"Meaning, it would be malpractice for this patient to show up and be first diagnosed with metastatic disease in May 2025. It is highly likely he was carrying a diagnosis of prostate cancer throughout his White House tenure and the American people were uninformed," he added.

Dr. Zeke Emanuel told MSNBC, "He did not develop it in the last 100, 200 days. He had it while he was President. He probably had it at the start of his presidency in 2021."

Over the weekend, the former president’s personal office released a statement on the illness, saying, “Last week, President Joe Biden was seen for a new finding of a prostate nodule after experiencing increasing urinary symptoms. On Friday, he was diagnosed with prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone.”
