Which groups of people are at high risk of developing cancer?

But in fact, the number of people suffering from cancer is increasing.

Data from the World Health Organization shows that currently one in five people in the world will develop cancer in their lifetime.

For my country, according to the latest data in 2020, the number of new cases of malignant tumors in my country has reached 3.929 million each year, and the number of deaths has reached 2.338 million.

So, can cancer be prevented?

1. Why is cancer always in the “late stage” when it first appears?

Anyone who pays attention to health knowledge knows that once cancer occurs, only early detection and early treatment can increase the cure rate!

But we have also discovered that many tumors are already in the late stages when they are discovered. Why is this?

Contrary to what everyone has previously known, in fact, many malignant tumors may not have any symptoms in the early stages! Most precancerous lesions are almost unnoticeable! Symptoms will not appear until the tumor compresses normal tissues and affects body functions.

Once the well-known "precursors" such as "long-term unexplained pain, unexplained weight loss, repeated infections, loss of appetite, persistent or frequent low-grade fever" appear, it often means that the tumor has grown and reached the middle or even late stage.

At this time, even if you go to see a doctor as quickly as possible, you may still delay the treatment.

In addition, these so-called "tumor symptoms" are not unique to tumors. Many common minor illnesses also have the same symptoms, so they are more easily ignored.

Therefore, to prevent cancer, you really can’t just rely on your own “feeling”!

2. Which groups are at high risk?

1. Elderly people

The older you are, the higher the incidence of tumors.

Generally speaking, the cancer incidence rate in people over 40 years old accounts for 94% of all cancers, so it is best for everyone to start cancer prevention physical examinations at the age of 40.

Women should undergo regular breast cancer screening starting at age 35 and cervical cancer screening after age 21.

2. People with family history

Tumors have a certain degree of familial clustering. People with a family history of tumors have a much higher tumor incidence rate than normal people, so these people are the key screening population for cancer prevention examinations.

Having fatty liver increases the risk of liver cancer. If you have high-risk factors for liver cancer such as hepatitis B, hepatitis C virus, long-term alcoholism, aflatoxin, family history of liver cancer, depression, etc., it is also recommended that you have a cancer prevention physical examination.

3. People with bad living habits

The occurrence of cancer is related to an unhealthy lifestyle, so the incidence of tumors in this type of people will also increase.

Especially those who have the following 5 bad habits should be more vigilant:

Drink hot water

The World Health Organization defines temperatures above 65°C as one of the carcinogenic factors. People who often drink hot drinks or eat hot foods above 65°C need to pay special attention to the screening of digestive system malignancies.

Love drinking

Alcohol is not only related to liver cancer, but also to some other cancers, such as cancer of the digestive tract, breast, ovary, etc. Studies have shown that there is no safe amount of alcohol, and even a small amount of alcohol is not good for health.

Love smoking

There is a direct relationship between smoking and lung cancer. In addition, hypopharyngeal cancer, esophageal cancer, laryngeal cancer, digestive tract cancer, breast cancer, etc. are all related to smoking.

Love processed meat

Red meat and processed meat have been clearly listed as carcinogens. Eating red meat regularly can easily induce gastrointestinal cancers such as colorectal cancer, breast cancer, ovarian cancer, etc.

Generally speaking, the total amount of red meat consumed per day should not exceed 50 grams.

Obese people

Basically all cancers in the body are related to obesity.

If you do not belong to the high-risk groups mentioned above, for young people in their twenties and thirties, routine physical examinations are sufficient and there is no need for cancer prevention physical examinations.

On the contrary, if you belong to the above group, you should pay attention to cancer prevention examinations.
