Fish is a favorite dish of many people, but if you are constantly fond of eating large quantities of fish, you should be careful. It can make you a victim of melanoma cancer (a type of skin cancer). A large-scale study of children in the united states found that people who ate large amounts of fish (tuna and unfried fish) had a higher risk of developing malignant melanoma.

According to study author Yunyang Cho, melanoma is the fifth most common cancer in the United States. Also, one in 38 whites will suffer from melanoma for the rest of their lives. At the same time, one in 1,000 black people and one in 167 Hispanics suffer from the disease. In fact, over the past decade, the trend toward fishing in the united states and europe has grown exponentially. At the same time, many previous research findings have shown inconsistencies between the relationship between fish eaters and the risk of melanoma. According to researchers, the results of this research have identified the relationship between the two, but further investigation is needed.

This is more dangerous

The researchers found that people who ate tuna and non-fried fish had a significantly higher risk of melanoma and stage IV. people who eat 14.2 grams of tuna a day have a 20 percent higher risk of melanoma and a 17 percent higher risk of stage 0 than people who eat 0.3 grams per day. At the same time, people who eat 0.8 grams of unfried fish per day have an 18 percent increased risk of melanoma and a 25 percent increased risk of stage-0 melanoma compared to those who eat 17.8 grams of unfried fish per day.

The risk increases to this extent

Researchers at Brown university in the US found that people who ate 42.8 grams of fish a day had a 22 percent higher risk of melanoma than those who ate 3.2 grams of fish a day. At the same time, people who ate 42.8 grams of fish per day had a 28 percent higher risk of developing abnormal cells in the outer layer of the skin. This is called stage-0 melanoma or melanoma in situ.

These were investigated

The researchers studied participants' BMI, smoking history, daily alcohol consumption, caffeine and calories, as well as their family history of cancer. During the study period, 5,034 (1.0%) people had melanoma, while 3,284 (0.7%) had symptoms of stage-0 melanoma.

This may be the reason

According to Yunyang Cho, we speculate that the cause of our findings may be fish contamination. Previous research has found that high fish intake is associated with higher levels of impurities in the body.
