“Below Deck Down Under” star Jason Chambers has been diagnosed with melanoma. The 52-year-old reality star publicly revealed his health news in an Instagram video on Dec. 16. “Update on the biopsy I had. It came back with melanoma,” Chambers explained in the video. “I’m in Australia. That was done in Bali. The Australian doctors, which are fantastic in Australia, they weren’t happy with what the indications told them to go to the stage two which would be to cut out a bigger section and test the glands.”
