A study has found that wolves in the Chernobyl Exclusion Zone may have developed resistance or resilience to cancer. These wolves, often referred to as mutant, appear to have evolved this ability potentially as a result of living in the area affected by the nuclear disaster. The extent and nature of this development is reported, though the language used to describe it varies, with some outlets framing it as an "anti-cancer ability" and others as "cancer-resilient" or "resistance to cancer".
