Being fat is not a blessing. Ten types of obesity are prone to cancer.

When it comes to obesity, the first diseases that come to mind are diabetes, high blood pressure, heart disease, etc. However, not long ago, a large-scale study found that overweight and obesity increase the risk of cancer, making people more susceptible to 10 types of cancer, including colon cancer, liver cancer, and thyroid cancer. To reduce the risk of cancer, staying away from obesity is a top priority.

Scientific research report: Ten types of cancer are "closely related" to obesity

An epidemiological survey conducted recently. The study was conducted among 5.24 million people in the UK, recording their body mass index and tracking their tumor development at the same time. The main content of the study is to evaluate whether there is a correlation between increased body mass index and increased tumor incidence. During the study, a total of 166,955 individuals were found to have tumors.

The results showed that the risk of 10 cancers was significantly associated with obesity, including uterine cancer, gallbladder cancer, kidney cancer, cervical cancer, thyroid cancer, leukemia, liver cancer, colon cancer, ovarian cancer and breast cancer. A person who is 1.6 meters tall and originally weighs 120 kilograms, if his weight increases to 136 kilograms, then the incidence of uterine cancer, gallbladder cancer, kidney cancer, cervical cancer, and thyroid cancer will increase. In fact, pancreatic cancer is also closely related to obesity. The most typical cases are Italian singing king Luciano Pavarotti and Hong Kong female artist Lydia Shum. Their diseases are related to being overweight.

Adults who gain half a pound every year are most likely to develop cancer

Coincidentally, just last week, the first national doctors' training course on "Nutrition and Disease Prevention" was launched in Nanjing. The national doctors' "Nutrition and Disease Prevention" textbook used has clearly pointed out that obesity is related to certain tumors. The textbook believes that in addition to the various chronic diseases that we are familiar with, obesity can easily lead to, according to statistics from the World Health Organization, 25%-35% of cancer cases worldwide are also directly related to obesity.

Experts in the United States have found that the occurrence of cancer is directly related to weight gain in adulthood. The average adult gains 227 grams, or almost half a pound, of weight each year, and their risk of developing cancer is much higher than that of ordinary people. Among them, those who gain 10 kilograms in adulthood have the highest risk of cancer.

A 28-year-old otaku weighing 200 pounds has colon cancer

Talking about cases of cancer caused by obesity, Yu Zhenghong was very moved by a 28-year-old colorectal cancer patient. "This young man is about 170 cm tall and weighs 200 catties. He will be out of breath after walking a few steps. The young man went to the hospital for examination due to frequent diarrhea and found that he was in the late stage of colon cancer. After questioning, it was found that he seldom eats at home. He always eats high-fat foods outside, such as hamburgers, cream cakes, etc. He also seldom exercises and likes to stay at home and play games." said the expert.

When the young man's mother learned that her child had cancer, she was very sad and couldn't understand it. She cried to the doctor: "My child is in good health, can eat and sleep well, how could he get colon cancer?"

The expert told the mother that colon cancer is also a cancer related to lifestyle. Eating high-fat foods for a long time will cause poor intestinal function and constipation, and the intestines will produce toxins, which will produce carcinogens over time. In addition, long-term eating habits of excessive high-fat foods will increase the secretion of bile acid in the intestines, causing irritation and damage to the intestinal mucosa. If the body is exposed to this kind of stimulation and damage for a long time, it is easy to induce colon cancer.

It has been observed that in many hospitals' colon cancer wards, almost all patients are fat people, and the vast majority of them are severely obese. Especially those who have obesity in the middle part, that is, those with a bigger belly, are more likely to suffer from colon cancer.

Why are overweight and obesity more likely to cause cancer?

Excessive body fat can affect hormone balance and increase the risk of cancer

Oncologists say that according to the results of epidemiological surveys, obese women are more likely to develop endometrial cancer and postmenopausal breast cancer, while obese men are more likely to develop prostate cancer; and as long as a person is obese, both men and women are more likely to develop colon cancer and rectal cancer. The more severe the obesity, the higher the incidence of the above cancers.

Why are overweight and obese people more susceptible to cancer? Experts explain that scientists have discovered several mechanisms that can explain the relationship between overweight or obesity and cancer. Excessive body fat can affect the balance of hormones in the body. Studies have shown that fat cells can release estrogen, which can increase the risk of cancer, such as breast cancer. Studies have also shown that fat, especially fat stored in the abdomen and waist, stimulates the body to produce cell growth factors. Excessive cell growth factors increase the risk of cancer.

Experts say that to reduce the risk of cancer, it is important to maintain a healthy weight and strive to keep your weight within a healthy body mass index (BMI) range. In addition, a high proportion of abdominal obesity is a characteristic and potential danger of obesity in the Chinese people. Men with a waist circumference greater than 90 cm and women with a waist circumference greater than 80 cm are considered to have abdominal obesity. When the body mass index is normal or not very high, if the waist circumference of women is greater than 89 cm and the waist circumference of men is greater than 99 cm, the harm is as great as that of those with a high body mass index. What is a healthy weight? Experts say measuring your body mass index (BMI) is a simple way to determine whether your weight is healthy and is suitable for most adults. The healthy body mass index for Asian adult men and women is between 18.5 and 22.9. To prevent cancer, you should keep your body mass index within a normal range.

What is fat?

Women with waist circumference exceeding 89 cm and men with waist circumference exceeding 99 cm should be alert. The obesity rate gradually increases with age, and only decreases after the age of 60.
