1. Current cancer situation


It is estimated that in 2018, the world has 18.1 million cases and 9.6 million deaths from cancer. The number of people globally alive 5 years after detection is 43.8 million (GLOBOCAN 2018 - project of the International Agency for Research on Cancer).
Vietnam ranks 2nd in the world in terms of cancer incidence. According to the data of the World Health Organization (WHO) 2014, each year Vietnam has 200,000 new cancer cases and 70,000 cancer deaths.
Why is that? How to reduce the incidence of cancer? This is a dilemma for the medical industry. To solve that problem, scientists are still delving into research to understand the causes of cancer. We now know that there are many causes of cancer.

Smoking 1 cigarette reduces life expectancy by 5.5 minutes; Every 6 seconds, 1 person dies from tobacco-related diseases; The number of deaths caused by tobacco is three times higher than the number of deaths from HIV and traffic accidents.
Through analysis, tobacco smoke contains more than 4000 chemicals, of which 43 chemicals are the cause of cancer, the most dangerous are tar, nicotine, addictive substances... In addition, in Cigarette smoke also has many tumor stimulants, stimulates respiratory tract infections, and damages blood vessels.

Effective exercise is exercise that requires sweating and increasing heart rate, such as: walking, swimming, cycling or jogging. Or any activity that avoids sitting too much can reduce the risk of cancer:
Colorectal cancer : Multiple studies that followed large groups of subjects over many years have shown that people exercise regularly have a lower risk of colorectal cancer. Although it is not known for sure why regular exercise can reduce cancer risk, people who exercise regularly have a 40-50% lower risk of colorectal cancer compared to people who do not exercise. Breast cancer: Similarly, women who exercise effectively more than 3 hours a week reduce the risk of breast cancer by 30-40%.. including women with genetic risk factors for breast cancer. Endometrial cancer: Many studies show an association between regular exercise and a reduced risk of endometrial cancer. Lung cancer: Many studies show that regular exercise reduces the development of lung cancer.

2.3 Limit alcohol content (wine, beer)


Drinking alcohol has been shown to significantly increase the risk of cancers of the oral cavity, oropharyngeal cancer, larynx cancer, and esophageal cancer. The risk is particularly high in people who both smoke and drink alcohol.
This is explained alcohol can help chemical toxins in tobacco penetrate more easily into the cells lining the mouth, throat and esophagus. At the same time, alcohol also reduces the ability to repair cells (DNA) damaged by toxins found in tobacco.
Recommendations of the American Cancer Society
The American Cancer Society recommends that we limit the amount of alcohol consumed in the body: men should not drink more than 2 units of alcohol (2 drinks) per day and women no more than 1 drink (1 drink) per day. Lower alcohol consumption is recommended for women because women's bodies are generally smaller than men's and women's elimination of alcohol is usually slower.
