Madonna's Brother's Cause of Death Finally Revealed.
Madonna's oldest brother, Anthony Ciccone, died at the age of 66 due to a combination of respiratory failure and throat cancer caused by smoking. He was receiving treatment at a Michigan nursing facility when he passed away, which was paid for by Madonna. Ciccone had struggled with alcoholism and homelessness for years, but was reintegrated into family life after a stint in rehab in 2017. Madonna had repeatedly offered to help him by paying for rehab, but he was not always receptive.
