As to why fish may cause melanoma, Cho said: “We speculate that our findings could possibly be attributed to contaminants in fish, such as polychlorinated biphenyls, dioxins, arsenic, and mercury.
“Previous research has found that higher fish intake is associated with higher levels of these contaminants and a higher risk of skin cancer.”
While previous studies have investigated this link, Cho was quick to add his study had not, reaffirming the need for more research in this area.
Although a link has been found between fish and skin cancer, it doesn’t mean people should stop buying fish altogether; fish is essential for providing nutrients the body needs for overall health.
