Captive NMRs are kept in colonies, and can inflict injuries on each other.
They do get cancer at very low rates.
Animals that haven’t been specially reared to have had zero contact with pathogens can also harbor dormant diseases, and the current longest-lived NMR has not spent his whole life in a sterile environment.
Complex organisms may be at a constant low-level risk of deadly internal injuries (i.e. a random stroke).
