How do Dolphins get cancer?

Dolphins, like many mammals, can develop cancer due to various factors, including genetic predisposition, environmental toxins, and exposure to pathogens. Research suggests that pollutants, such as heavy metals and industrial chemicals in their habitats, may contribute to the incidence of tumors in these animals. Additionally, stress and immune system suppression can play a role in their vulnerability to cancer. Overall, the exact mechanisms are complex and still under investigation.
