Since 20 years ago, researchers have proven that sedentary lifestyles and poor diet are among the causes of cancer. At that time, they found that very high fat in the body can change levels of hormones such as insulin, estrogen, and testosterone, which can increase tumor growth.
Various studies have proven that fat that is too high in the body causes an increased risk of degenerative diseases, such as coronary heart disease, stroke, heart failure, diabetes mellitus, and even death. Fat that is too high results in bodily functions not functioning properly, abnormal hormones, and blockages in blood vessels. There are an estimated 640 million people who are obese in the world. While obesity has caused 4.5 million deaths in 2013. WHO states that fat in the body can trigger the emergence of various types of cancer. This was reported in The New England Journal of Medicine.
What types of cancer might arise in obese people?
This statement emerged from the results of an analysis of 1000 studies that have conducted research on the factors that cause cancer. International Agency for Research on Cancer (IARC) has identified from 1000 studies conducted from various parts of the world, it is known that the following are 13 types of cancer most likely to occur due to obesity and excess fat in the body, namely:
- Throat or esophageal cancer
- Stomach cancer, especially cancer of the stomach
- Bowel cancer
- Heart cancer
- Bladder cancer
- Pancreatic bladder cancer
- Breast cancer, is very risky when a woman has experienced menopause
- Cervical cancer
- Ovarian or ovarian cancer
- Kidney cancer
- Cancer of the lining of the brain
- Thyroid gland cancer
- Multiple myeloma, which is a type of white blood cell cancer
According to the analysis that has been done, people who are obese with a body mass index (BMI) of more than 30 kg / m2 have a 5 times higher risk of developing esophageal cancer compared with people who have a normal BMI. While the obesity group is at risk for developing colon, stomach, liver, pancreas, and kidney cancers 2 times higher than people with good nutritional status. The highest risk of cancer is uterine cancer, with a 7 times greater chance in the obese group of people.
Almost all research analyzed by IARC involves respondents who have unhealthy lifestyles, rarely exercise, and consume foods high in fat, energy, and sugar. Most studies do look at the relationship between body fat levels with recurrence in cancer patients.
What does cancer have to do with weight?
People who have an ideal body weight are people who have a normal body mass index value, which is between 18.5 to 24.9. While those who have a body mass index between 25 to 29.9 can be called overweight or overweight, and those who have a BMI of more than 30 have been declared obese.
Almost all studies analyzed concluded that being overweight is associated with an increased risk of cancer. Obesity is indeed associated with metabolic and hormonal disorders, such as the hormone insulin and insulin-like growth factor (IGF), and inflammation of the body’s organs. Scientific results prove that sexual hormone metabolic disorders and chronic inflammation caused by excessively high levels of fat are one of the triggers for cancer.
Then how to avoid cancer?
Many simple things you can do to prevent this disease from happening, one of them is by maintaining your normal weight. Normal weight can be obtained by doing regular exercise, choosing foods that are high in fiber, vitamins, and minerals, limiting sugar, salt, and fat, and doing small things like weighing regularly, eating small portions but often , and eat at regular hours. These things can reduce the risk for obesity and various other degenerative diseases, such as cancer.
