I saw discussion about Mel Gibson repeating a claim that ivermectin cured cancer. Is there reliable evidence for that, or is it speculation?

That claim alone is not evidence. Ivermectin is an antiparasitic drug, and there is no established proof that it cures cancer in people. Lab findings or anecdotes, if that is what the claim rests on, do not show that a treatment works safely and reliably in patients.

Be wary of the word “cure” here. To support it, you would need well-designed human studies showing meaningful outcomes, not just a celebrity repeating a story or people attributing an improvement to one drug. Cancer types and treatments differ, so a sweeping claim needs especially strong evidence.

So there isn't enough to treat it as a proven cancer therapy?

Right. It should not replace established cancer care. Anyone considering a medication alongside treatment should discuss it with their oncology team, since self-medicating can carry risks and complicate care.
