Bernie Madoff, apparently in possession of an organ resembling a heart, suffered a cardiac arrest last month. And, according to reports, he also has serious kidney problems.

CNBC reports that the 75-year-old has stage-four kidney disease; other outlets are reporting kidney cancer; CNBC says Madoff emailed them to say that he's not currently receiving dialysis. According to CBS, which reported a cancer diagnosis:

That diagnosis means the cancer may have spread to nearby organs or lymph nodes, according to the Cleveland Clinic.

Madoff is supposed to be serving a 150-year sentence at Butner Federal Correctional Complex, a North Carolina federal prison, but authorities moved him to the Duke University Medical Center after his heart attack.

According to a press release, he has since been moved back to the medium-security prison, located near Raleigh.

Madoff's only living son, Andrew Madoff, has also been receiving chemotherapy for stage-four cancer.
