Wall Street swindler Bernard Madoff is telling fellow inmates he’s dying of cancer, the New York Post reported Monday.

Madoff, 71, is serving 150 years in a North Carolina prison for conducting the largest Ponzi scheme in history.

The New York Post reports he’s been telling inmates he does not expect to live much longer and, according to one inmate, takes 20 pills a day.

His lawyer did not return messages yesterday but, when previously asked by The Post, would neither confirm nor deny his client has cancer. A lawyer for his wife, Ruth, also did not return messages.

Sources also told The Post Madoff has been participating in a Native American “sweat lodge” while in prison as part of a purification ritual.

Madoff was quickly assigned a job in the prison’s engraving section when he first arrived, but last month he was transferred to a job painting fences.
