Harvey Weinstein has been diagnosed with a form of bone marrow cancer, according to US media reports.

The disgraced Hollywood movie producer has chronic myeloid leukemia and is undergoing treatment in a New York prison, according to NBC News.

His reported diagnosis comes after a string of health issues for the once-powerful entertainment mogul, who appeared pale and visibly frail during a brief court appearance in September.

The 72-year-old also underwent emergency heart surgery last month, after which his representative said he was “out of danger at the moment”.

Juda Engelmayer, Weinstein’s spokesman, said it was “troubling” that his health issues “have become a subject of public discourse”.

“Out of respect for Mr Weinstein’s privacy, we will offer no further comment,” Engelmayer told AFP.
