Summary: Eating higher levels of fish, including tuna and non-fried fish, appears to be associated with a greater risk of malignant melanoma, suggests a large study of US adults.

Eating higher levels of fish, including tuna and non-fried fish, appears to be associated with a greater risk of malignant melanoma, suggests a large study of US adults published in Cancer Causes & Control.

Eunyoung Cho, the corresponding author said: "Melanoma is the fifth most common cancer in the USA and the risk of developing melanoma over a lifetime is one in 38 for white people, one in 1,000 for Black people and one in 167 for Hispanic people1. Although fish intake has increased in the USA and Europe in recent decades, the results of previous studies investigating associations between fish intake and melanoma risk have been inconsistent. Our findings have identified an association that requires further investigation."

Researchers from Brown University, USA found that, compared to those whose median daily fish intake was 3.2 grams, the risk of malignant melanoma was 22% higher among those whose median daily intake was 42.8 grams. They also found that those whose median daily intake was 42.8 grams of fish had a 28% increased risk of developing abnormal cells in the outer layer of the skin only -- known as stage 0 melanoma or melanoma in situ -- compared to those whose median daily intake was 3.2 grams of fish. A portion of fish is approximately 140 grams of cooked fish.

To examine the relationship between fish intake and melanoma risk, the authors analysed data collected from 491,367 adults who were recruited from across the USA to the NIH-AARP Diet and Health Study between 1995 and 1996. Participants, who were aged 62 years on average, reported how frequently they ate fried fish, non-fried fish, and tuna during the previous year as well as their portion sizes.

The researchers calculated the incidence of new melanomas that developed over a median period of 15 years using data obtained from cancer registries. They accounted for sociodemographic factors, as well as participants' BMI, physical activity levels, smoking history, daily intake of alcohol, caffeine and calories, family history of cancer, and the average UV radiation levels in their local area. 5,034 participants (1.0%) developed malignant melanoma during the study period and 3,284 (0.7%) developed stage 0 melanoma.

The researchers found that higher intake of non-fried fish and tuna was associated with increased risks of malignant melanoma and stage 0 melanoma. Those whose median daily tuna intake was 14.2 grams had a 20% higher risk of malignant melanoma and a 17% higher risk of stage 0 melanoma, compared to those whose median daily tuna intake was 0.3 grams. A median intake of 17.8 grams of non-fried fish per day was associated with an 18% higher risk of malignant melanoma and a 25% higher risk of stage 0 melanoma, compared to a median intake of 0.3 grams of non-fried fish per day. The researchers did not identify significant associations between consumption of fried fish and the risk of malignant melanoma or stage 0 melanoma.

Fish is healthy - fish isn't healthy - ....

I am so sick to death of all these stupid supposedly "scientific" nutrition studies.  They're all a crock of sh*t.

[LMAO]

I’ve been a fisherman ever since I’ve been able to walk and have been eating fish ever since I can remember and I’m 56 years old now and in excellent health

These are the same folks that not long ago were telling people not to eat eggs and fat because it’ll kill you and instead fill up on white rice, bread, white potatoes without skin etc. etc.

LOL!  You're absolutely right.

Probably sponsored and/or paid for by the American Beef Association.

@Kamaji  @LMAO

But I have frowned on some of the stories about farm-raised Tilapia. 

Funny how it's a popular, mild white fish, which would do well in this current market.

Yup.  And the same idiots who were telling people all sorts of other nonsense even earlier.

I wish this 'scientist' Eunyoung Cho would instead do a study on the detrimental effects of wearing masks and the need to remove masks as they contribute to the retention of CO2 which is dangerous to a person trying to breathe normally.

Or one of the many PETA front groups pushing everyone to go vegan. "Fish are friends, not food!"

Exactly. Eating fish, I'm sure you are in excellent health (good for you).

I used to eat fish as a kid; northern, smoked trout, bass, blue gill, perch when my Dad fished.  I'm more of a meat lover. When we moved to FL I loved grouper, but that particular fish contains toxins so I stopped eating fish altogether.

I ate a lot of fish, oysters, clams and crab as a kid in MD, fresh caught if I got off my butt and did it (didn't know how good I had it). I only eat the occasional can of tuna nowadays, now that I am about as far from salt water as I can get in North America.
