The American Cancer Society (ACS) has released a first-grade cancer first-time fight plan for the next 10 years, called the "2030 Blueprint for Cancer Prevention and Mortality Reduction," published in the journal CA, the world's highest impact factor journal!

In 80 years, cancer mortality has fallen by 26%!

The article analyzes in detail the changes and causes of cancer mortality in the United States during the 80-year period from 1930 to 2010, and plans for the future work to reduce cancer mortality.

Cancer mortality in men and women in the United States from 1930 to 1980. It can be seen that the year with the highest cancer mortality rate in the United States was 1991. The total death rate for this year was 215.1/100,000. By 2015, the total cancer death rate in the United States has dropped to 158.7/100,000. 26%!

American Cancer Society: Three major factors in mortality reduction!

Cancer is first of all prevention. Smoking has greatly affected a variety of cancers, including lung cancer. Therefore, reducing cancer mortality depends on smoking cessation.

Followed by screening, the emergence of screening, greatly affecting the prognosis of colon cancer and cervical cancer. Although breast cancer and prostate cancer screening have different degrees of controversy, they still contribute.

Improvements in surgical procedures and reductions in complications have resulted in reduced operative mortality, advances in radiotherapy methods have reduced patient mortality, and systemic treatment advances in the blood and lymphoid tumors have also reduced mortality.

10 major anti-cancer strategies in the next decade!

1 away from 11 pathogens

Some viral infections (such as HPV, HIV, and hepatitis B virus) also increase the risk of cancer.
Currently, a total of 11 pathogens have been identified as carcinogenic by the International Agency for Research on Cancer (IARC), including:

1 species of bacteria: Helicobacter pylori;
Seven viruses: hepatitis B virus, hepatitis C virus, human papilloma virus (HPV), EB virus, human immunodeficiency virus, and the like.
Three species of parasites: liver flukes of Thailand, Clonorchis sinensis (liver fluke), and Schistosoma japonicum.

For infections that are common in everyday life, we recommend:
- 1 Cervical cancer - HPV human papilloma virus
Routes: sexual transmission, close contact, indirect contact (infected clothing, daily necessities, utensils, etc.), iatrogenic infections, mother-to-child transmission.
Prevention: Inoculation of HPV vaccine, attention to personal hygiene, and attention to sexual hygiene. For women who have had sex, it is best to do a screening every year.
Reminder: There is no obvious symptom in the early stage of HPV infection. After cervical lesions, there may be sexual contact bleeding, increased vaginal discharge and odor, and prolonged menstrual flow during menstruation.

- 2 Gastric cancer - Helicobacter pylori
Pathway: oral saliva, manure hand, food contact
Prevention: Wash your hands before meals, try not to feed food, especially not to feed your children. Can be divided into meals or public chopsticks, and tableware is often disinfected.
Reminder: If you have symptoms such as bad breath, pantothenic acid, stomach pain, etc., you should do a gastroscopy and hp infection screening.

- 3 Liver cancer - hepatitis B and hepatitis C virus, liver fluke
Pathway: blood transmission, mother-to-child transmission, sexual transmission, raw freshwater fish and shrimp, etc.
Prevention: vaccination against hepatitis B and hepatitis C; go to regular medical institutions during blood donation or blood transfusion; do a good job in pregnancy check; eat raw freshwater fish and shrimp.
Reminder: Patients with chronic hepatitis B and C may have symptoms such as fatigue, loss of appetite, and indigestion. Do not underestimate.

- 4 Nasopharyngeal carcinoma - Epstein-Barr virus
Pathway: saliva transmission
Prevention: Inoculate EB vaccine, taking care to avoid mouth-to-mouth transmission and sneezing droplets.

2 sunscreen, reduce the risk of skin cancer

Sun exposure is the biggest risk factor for skin cancer. Almost 86% of melanoma skin cancers and 90% of non-melanoma skin cancers (including basal cell carcinoma and squamous cell carcinoma) are associated with solar ultraviolet radiation. The most effective way to limit your risk of skin cancer is to limit your exposure to sunlight.

Sunbathing is a good way to add vitamin D, but we refuse to expose it!
- 1 Avoid direct sun at noon;
- 2 Proper use of sunscreen;
- 3 wear wide visor and sunglasses;
- 4 wear sun protection clothing;

3 reduce unnecessary medical radiation

The IARC believes that all ionizing radiation is carcinogenic. Data for 2006 showed that 48% of ionizing radiation comes from medical devices (such as CT), including exposure during diagnosis and treatment.

Medical ionizing radiation is associated with a variety of cancers, with the greatest risk of CT. After a single CT coronary angiogram, a 40-year-old man and woman had a lifetime cancer risk of approximately 1 in 600 and 1/270, respectively, but the risk of head CT was much smaller (1/11080 and 1/8100).

However, older people are at lower risk of accepting these tests.

4 reduce indoor building materials emissions

radon pollution, formaldehyde pollution, benzene pollution, etc. all have an impact on health. Among them, earthworm pollution has been confirmed by the World Health Organization as the second most basic lung cancer substance after tobacco. According to estimates by the National Research Council, 3% to 4% of lung cancer deaths in the United States can be prevented by reducing indoor exposure to sputum.

- 1 radon: A radioactive gas that is widely found in nature. Building materials are the main source of indoor enamel, such as slag bricks and natural stone used for decoration, as well as ceramic products such as tiles and sanitary ware.

- 2 Formaldehyde: mainly from wood-based panels used in decoration and furniture, such as laminate flooring, large core panels, MDF, and white latex and fabric products for decoration.

- 3 Benzene: mainly from solvent-based wood lacquers, paints, solvent-based adhesives and detergents.

Before decorating a new home, it is recommended to have a professional testing agency conduct an indoor environmental test. According to the test results, it is decided whether or not you can stay. If the pollution is not serious, it is best to ventilate for about 6 months. More ventilation in the home can reduce the concentration of indoor sputum and formaldehyde.

The World Health Organization recommends that the indoor radon concentration should be <2.7pCi/L. The US Environmental Protection Agency recommends that indoor radon concentrations ≥ 4.0 pCi/L exceed the standard.

5 Smoking cessation is a top priority!

Controlling tobacco is the "top priority" for cancer prevention! Since 1991, cancer deaths in the United States have decreased by 26%, more than half of which is attributed to a decline in smoking rates.

- 1 Quit smoking is good for people of all ages.
- 2 Smoking causes a reduction in life expectancy of more than ten years.
- 3 If you quit smoking before the age of 40, you can regain 9 years of life.

6 alcohol limit, any drinking is harmful

In 1987, the International Agency for Research on Cancer (IARC) classified alcohol as a carcinogen for the first time. Excessive drinking can cause adverse effects in many aspects of the body, at least in relation to seven types of cancer (British Science Monthly, Addiction).

The American Cancer Society recommends that no more than one female drink per day and no more than two males. The Chinese Dietary Guidelines (2016) suggest that men should drink no more than 25 grams of alcohol a day, and women should not exceed 15 grams, otherwise they will drink too much.

What is the concept of 25 grams of alcohol? Probably converted, remember:
-  white wine: do not exceed 1 or 2 each time
-  Beer: Do not exceed one bottle at a time
Red wine: every time you limit it to a red wine glass

Evidence suggests that even small amounts of alcohol can increase the risk of certain cancers, including breast cancer. Therefore, in order to prevent cancer, drinking is not recommended.

7 control weight

Obesity not only increases the risk of heart disease, diabetes, bone and joint disease, but also increases the risk of cancer. More than 20 different types of cancer are associated with obesity, the most notable of which are rectal cancer, endometrial cancer, and esophageal adenocarcinoma.

8 healthy diet

Bacon, ham, sausage, and hot dogs are listed as the first group of carcinogens by the World Health Organization. Eating processed meat increases the risk of colorectal cancer by 18%. Red meat also shortens people's life and increases the risk of colon cancer, especially when the meat is grilled or grilled, or even slightly burned. Although the risk of carcinogenicity of red meat is far less than the risk of smoking, reducing the intake of red meat and limiting the consumption of processed meat will only reduce your risk of cancer.
Eat a wide variety of foods every day – fruits, vegetables, cereals, protein and dairy products – and consume a lot of food every day. It also means observing the fats, fats, sodium and sugar you eat. The more you can avoid getting fat, the better. Maintaining your healthy height and weight during your lifetime can reduce your risk of heart disease, diabetes and cancer. Start a healthy diet today!

9 sports, sports, sports

Physical exercise not only helps to lose weight or maintain body shape, but also has a preventive effect on cancer. Exercise seems to reduce hormone levels, improve our immune system function, lower insulin and insulin-like growth factor levels, and lower body fat.

Studies have shown that people who exercise at least 30-60 minutes of moderate to high-intensity physical activity every day have a reduced risk of developing cancer, especially breast and colon cancer. In addition, the incidence of several other cancers has also declined, including prostate cancer, lung cancer and endometrial cancer.

To prevent cancer, the US Sports Guide recommends:
- Adults should perform at least 150 minutes of moderate-intensity aerobic exercise (such as brisk walking) per week;
- or 75 minutes of high-intensity exercise (such as jogging);
- or an equal amount of two sports combinations.

10 for cancer screening

For most cancers, survival can be greater if it is detected and treated early. Regular screening for the following cancers is required:
Breast cancer screening, cervical cancer screening, colorectal cancer screening, hepatitis C virus screening, HIV screening, lung cancer screening, obesity, etc.
