Lazy cancer, embarrassing cancer, delaying cancer…

Nowadays, there are many words with “cancer” popular on the Internet. Although it is just a joke, I have to say, True cancer is becoming more common.

In 2022, the latest data released by the National Cancer Center shows that there are about 4.064 million cases in China every yearNew cancer, about 2,413,500 deaths2.4135 millioncases. trend. On average, this equates to 464 diagnoses and 276 cancer deaths per hour.

First, the number of cancers is increasing, and age is the main factor

< span>Speaking of the reasons for the high incidence of cancer, it seems that everyone can put forward several points, such as environmental pollution, bad habits, etc., but experts point out that age is one of the biggest risk factors for cancer.

Clinically, the incidence of most cancers increases rapidly after the age of 45, because tumors need to go through a long period of gene mutationandimmune escapeprocess.

Let’s start with genetic mutations.

The premise of cell carcinogenesis is gene mutation, and related genes are divided into two categories: “oncogene” and “tumor suppressor gene”.

oncogenes promote cell growth, and when mutated, increased activity stimulates cell proliferation. And tumor suppressor gene can inhibit cell growth. Once mutation occurs, the activity is lost and cell growth is not restricted.

But cancerous cells do not necessarily produce tumors, because a small number of cancer cells can be cleared by the immune system, unless, they are immune escape.

immune escape meansMutant cells escape the immune system’s “supervision” and “pursuit”. The human immune system is very powerful, not only can kill disease-causing bacteria and viruses, but also remove abnormal mutant cells, unless the number is too large for the immune system to cope with.

The fight between cancer cells and the immune system can be divided into 3 stages:

The first The first stage is immune clearance, and immune cells have an absolute advantage;

The second stage is immune balance, where individual cancer cells acquire the ability to coexist with immune cells, and immune cells cannot completely eliminate all of them Cancer cells;

The third stage is immune escape, the immune system loses its regulatory function, cancer cells grow explosively, tumors appear, and even begin to metastasize.

Both processes are relatively slow, Therefore, the occurrence of cancer takes time to accumulate, an average of more than ten years. In other words, the longer you live, the higher the accumulation of genetic mutations and the probability of immune escape, and the greater the risk of cancer.

Data also confirm this, the National Cancer Center report shows that the incidence and mortality of cancer in my country strong>peaks after the age of 80,diagnostics and deathsthe highest in the 60-79 age group.

Second, there is no warning in the early stage of cancer? Authoritative reminder

Many cancers have no obvious symptoms in the early stage, because cancer cells “camouflage” and express proteins similar to normal cells to escape the recognition of the immune system.

The lack of symptoms does not mean the absence of symptoms at all. According to the “Core Information on Cancer Prevention and Control” issued by National Health and Medical Commission CDC, we Pay attention to the cancer danger signals sent by your body, and seek medical attention in time if you notice abnormal symptoms.

Specific abnormal symptoms include:

Third, keep in mind the 5 sets of cancer prevention figures, and benefit for a lifetime

Faced with the constantly high incidence of cancer, How can we prevent cancer? Keep these numbers in mind and start with different aspects of your life.

Exercise 150 minutes per week

Exercise is a good anti-cancer150 minutes of moderate-intensity exercise, or 75 minutes of high-intensity exercise per week Intensity exercise.

Moderate-intensity exercise generally refers to exercising where you feel warmer and breathe faster, but you can still talk, such as brisk walking, swimming, dancing, and cycling. High-intensity activities generally refer to those that raise your heart rate, sweat and pant, such as running, football, and aerobics.

Sit for less than 1 hour, get up and walk for 2 minutes

American Cancer Society Studies have shown that people who sit for more than 6 hours a day have a 19% higher risk of premature death, including cancer death, than those who sit for less than 3 hours. Prolonged sitting is one of the recognized risk factors for cancer.It is recommended to sit for no more than 1 hour at a time, and get up and walk for about 2 minutes during this period .

Do not drink a drop of alcohol

Alcohol is a class of carcinogens, and even a small amount of alcohol per day can increase the risk of cancer.

The Global Burden of Disease report published in The Lancet shows that alcohol consumption poses great risks to health and is closely related to premature death, cardiovascular disease and cancer. Moreover,there is no safe range for drinking alcohol, and only abstaining from alcohol can minimize the harm.

Eat 5 servings of fruits and vegetables a day

Research shows that whether it is regular fish and meat, Or perennial vegetarian, is not conducive to cancer prevention. The best anti-cancer diet is to achieve a nutritional balance, try to eat natural ingredients, reduce the intake of processed foods, and increase the intake of dietary fiber. Into, eat at least 5 servings of vegetables and fruits every day (1 serving is about 85 grams).

BMI between 18.5 and 24

Obesity is a risk factor for cancer , related to 14 different cancers including thyroid cancer, liver cancer, stomach cancer, and kidney cancer. In life, you should pay attention to control your weight, and keep your body mass index (BMI) within the range of 18.5~24.

If you want to stay away from cancer, it is recommended to keep the above cancer prevention numbers in mind, especially in 45 After the age of middle-aged and elderly people, the immune system of the body gradually declines, and the incidence of cancer begins to rise. It is necessary to develop a healthy lifestyle, pay more attention to abnormal symptoms of the body, and conduct regular physical examinations and screenings.
