Regular Screening Skin cancer screening is important. According to a study, eating fish can also increase the risk of black skin cancer.

Scientists in the United States have made an interesting discovery: Analyzing data from hundreds of thousands of test people showed that fish consumption can increase the risk of skin cancer.

Indeed, fish is healthy. Contains iodine, vitamin D and proteins. Fatty species such as salmon and mackerel also provide omega-3 fatty acids, which strengthen the immune system and have an anti-inflammatory effect. Nutrition experts therefore recommend eating fish twice a week. But now a study has found that people who eat fish regularly may have a higher risk of black skin cancer.

Fish is said to increase the risk of skin cancer

Anyone who loves fish is said to have a higher risk of developing black skin cancer. This is the result of a study by Brown University (USA), which analyzed data from over 490,000 initially healthy subjects with an average age of 62. As part of the study, participants reported how high their fish consumption had been in the previous year, how often and in what form – fried or not fried – they ate fish.

Researchers collected information over a 15-year period and, on this basis, examined the connection between fish consumption and the onset of skin cancer. Socio-demographic factors and the participants’ body mass index were also taken into consideration. Range of motion, cancer in the family, alcohol, tobacco and caffeine consumption, calorie intake and average UV radiation in the vicinity of the participants were also taken into consideration, as reports.

During the study period, 5034 subjects developed malignant melanoma and a further 3284 cases of early stage skin cancer were discovered. According to the scientists, the high consumption of fish increased the risk of both forms of cancer.

How much fish increases the risk of skin cancer?

Most importantly, an increased consumption of fish and non-fried tuna is said to increase the risk of malignant melanoma and early-stage melanoma. Those who ate an average of 43 grams of fish per day had a 22 percent higher risk of malignant melanoma and a 28 percent higher risk of early-stage cancer than those who ate only 3 grams. An average serving is around 140-170 grams of fish.

Possible reasons fish could cause skin cancer

In a university statement, co-author Eunyoung Cho assumes that it is not the fish itself that is dangerous to health, but the mercury it contains. “We suspect our findings may be due to pollutants in fish such as polychlorinated biphenyls, dioxins, arsenic and mercury,” said Cho. ‘Previous research has found that increased consumption of fish is associated with higher levels of these substances in the body and has found a link between them and a higher risk of skin cancer.’ Since the present cancer study did not measure how many and what pollutants the subjects had in their bodies, more studies are now needed to confirm the connection.
