Links between pollution and cancer in wild animals: what can we learn?
This recent review combines the information available on cancer occurrences in aquatic and semi-aquatic animals. Cancer is one of the pollution-induced diseases that should be at the centre of attention in ecological and evolutionary research. Authors suggest physiological mechanisms that link pollution and cancer, determine which types of aquatic animals are more vulnerable to pollution-induced cancer, which types of pollution are mainly associated with cancer in aquatic ecosystems, and which types of cancer pollution causes.
