The creator of the comic strip “Dilbert,” Scott Adams, says he is battling the same aggressive prostate cancer as President Biden and only has months to live.

The outspoken conservative commentator made the disclosure during a livestream on Monday.

“I have the same cancer that Joe Biden has. Uh, so I also have prostate cancer that has also spread to my bones,” Mr. Adams said during the livestream. “But I’ve had it longer than he’s had it. Well, longer than he’s admitted having it. So, my life expectancy is maybe this summer.”

Mr. Adams also responded to the swirling speculation about Mr. Biden apparently not previously knowing about the cancer despite having top-level medical care and monitoring while in the White House.

“You might ask yourself, ‘Is it possible that he [Mr. Biden] was not showing signs in August of 2024, but that between then and now, that he not only showed signs but that it had spread to his bones?’” he said. “And the answer is, ‘Yeah, that’s possible.’”

He also shared that alternative treatments he had touted online, such as taking ivermectin and fenbendazole, had proved unsuccessful.

“I was making a big deal online about the claims that ivermectin and fenbendazole are a cure for this exact condition. Well, in case you’re wondering, I did try that,” he said. “It wasn’t that I believed it would work, it was just that there wasn’t much downside risk. So, with my doctor’s blessing, he didn’t think it would work, of course. And it didn’t work at all.

Last week, Mr. Biden’s office announced that a “small nodule” was detected on his prostate during a routine physical examination, requiring further evaluation.

“On Friday he was diagnosed with prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone,” the office said in a statement. “While this represents a more aggressive form of the disease, the cancer appears to be hormone-sensitive which allows for effective management. The President and his family are reviewing treatment options with his physicians.”
