This was revealed in a medical study conducted in the United Kingdom.
The Oxford University study examined the relationship between eating habits and cancer risk in data from more than 472,000 people.
The data was collected between 2006 and 2010 and people ranged in age from 40 to 70.
These people were asked how many times each week they ate meat and fish and based on that the rate of cancer cases was estimated.
All other factors such as diabetes, social, economic and lifestyle were also taken into consideration.
2,47,571 (52%) people more than 5 times a week, 25,382 (44%) people 5 times a week or less, while 22% were accustomed to eating only fish and the remaining 2% to vegetables Were limited.
During the research period, 54,961 people were diagnosed with cancer.
Researchers have found that people who eat meat 5 times a week or less have a 2% lower overall risk of cancer.
Similarly, the risk is reduced by 10% for those who prefer fish instead of meat and up to 14% for those who prefer vegetables.
Those who ate meat five times a week or less had a 9% lower risk of bowel cancer, the researchers said.
Similarly, it was found that the risk of bladder cancer was reduced by 20% in men who ate fish alone and by 31% in those who ate vegetables.
If middle-aged women prefer vegetables to meat, they can reduce their risk of breast cancer by 18%, as they are more likely to lose weight than women who eat meat.
The researchers said that while this was an observational study, the link between diet and cancer could not be finalized and more research was needed.
He said further research is needed to find out how low or non-meat diets reduce the risk of cancer in people.
