Were There Rumors About Michael Landon’s Death? – Separating Fact from Fiction
Several rumors about Landon’s death have circulated over the years. One persistent claim is that he died of AIDS, but reliable sources consistently identify pancreatic cancer as the cause, with spread to the liver. The rumor appears to have stemmed from homophobia related to Landon’s close friendships with gay co-stars, though credible evidence is entirely absent.
Another recurring rumor is that his cancer may have been caused by conditions on the Little House on the Prairie set. Available reporting indicates that credible evidence for this claim is scant.
