As a member of union for international cancer control, the Taiwan Province Cancer Foundation has advocated the "Five Exercises for All" cancer prevention publicity program for many years. Professor Lai Jiming, the executive director of the Taiwan Province Cancer Foundation, also called for: cancer can be prevented, and changes in living habits, including diet, exercise, obesity, smoking and so on, are closely related. Practicing these five healthy lifestyles can reduce the mortality by 6-7%.

1. Good habit of cancer prevention: Rainbow of Fruits and Vegetables 579

Nutritionist Xu Jiayun of Taiwan Province Cancer Foundation emphasized that phytochemicals in fruits and vegetables exist in colorful fruits and vegetables, so we should follow the dietary principle of Rainbow of Fruits and Vegetables 579, and take enough fruits and vegetables, that is, 9 servings for men, 7 servings for women and 5 servings for children every day.

Modern office workers live a busy life, and many people often use quick and convenient comprehensive vitamins or nutrients to replace nutrient intake. However, at present, there is not enough evidence that nutritional supplements (health food) can prevent cancer, and even some vitamins or nutritional supplements may interact with the efficacy of western medicine, or are harmful to the health of certain ethnic groups. Therefore, it is recommended to take natural fruits and vegetables with diversified colors.

2. Good habit of cancer prevention 2: Regular exercise (more than 15 minutes per week, more than 3 minutes for dieters)

According to the research of National Health Institute, 15 minutes of exercise every day can prolong the life span of 3 years and reduce the risk of cancer death by 1%. Regular exercise can not only control weight, but also be the key to maintain a healthy posture.

Exercise for at least 3 minutes a day and more than 15 minutes a week is helpful to prevent colorectal cancer, breast cancer, endometrial cancer, pancreatic cancer and renal cancer.

3. Good habit of preventing cancer 3: weight control

Obesity is a warning sign of cancer. Studies show that if the weight exceeds 4% of the ideal weight of the individual, the risk of cancer will increase by 33% for men and 55% for women. To maintain weight, the body mass index (BMI) must be controlled between 18.5 and 24, or the waist circumference of men should not exceed 9 cm and that of women should not exceed 8 cm.

4. Good habit of preventing cancer 4: Stay away from smoking, and pay more attention to electronic smoking

Chewing betel nut will not only cause serious damage to teeth and periodontal tissue, but also cause cancer of mouth, pharynx, larynx and esophagus, so don't bury carcinogenic factors for a small appetite.

According to the research, about 3% of cancer deaths are related to smoking, and it is not only the smokers themselves who are at risk, but second-hand smoking is no less harmful to health. However, the rise of electronic cigarettes in recent years has become a global health loophole. Many people think that electronic cigarettes will not produce tar and will not cause cancer. However, this statement has been broken.

Formaldehyde in electronic tobacco has been listed as a first-class carcinogen by the International Center for Research on Cancer (IARC), which may cause cancer. Even if you choose tobacco oil without nicotine, it will still affect the health of your lungs and there is a risk of psychological addiction.

5. Good habit of preventing cancer 5: Regular screening

Faced with the rising number of cancer patients and the increasing medical expenditure, regular screening is an effective tool for early detection of cancer and reduction of mortality. At present, * * * provides free screening for four common cancers (colorectal cancer, oral cancer, breast cancer and cervical cancer) in China.
