In today's society, we still "talk about cancer". According to the release of the Chinese Center for Disease Control and Prevention, there are more than 3.5 million new cancer cases and more than 2 million deaths in China every year.

What is cancer?

Cancer is a genetic disease, which refers to the genetic alteration of cells under the effect of carcinogenic factors, causing the body to lose the normal regulation of its growth, resulting in infinite genetic growth, which can also be transferred to various parts of the body, destroying the normal organ structure, causing the body to dysfunction and threatening life. The common cancers in China include: lung cancer, breast cancer, stomach cancer, colon cancer, liver cancer, esophageal cancer, nasopharyngeal cancer, bladder cancer, cervical cancer, pancreatic cancer, etc.

Is cancer contagious or not?

Is cancer really contagious?

No! Wrong! Wrong!

Cancer cells have the ability to infiltrate into the surrounding area and metastasize with blood and lymphatic vessels, which will eventually form large metastases and infiltrations in the patient's body. However, it is obviously not scientific to say that cancer is an infectious disease!

It is because cancer cells will die rapidly due to the loss of nutrition after they are separated from the human body. It does not have characteristics such as infectious source and infection channel, so the nature of cancer is just a genetic disease and has nothing to do with infection!

What are the cancer triggering factors?

[Breeze] Bad living habits: smoking, intake of large amount of strong alcohol, high-calorie and high-fat diet for all machines, contamination of drinking water, moldy food, etc.

[Breeze] Environmental factors: chemical or physical carcinogens in the environment enter the human body through the body surface, respiratory tract and digestive tract to induce cancer.

[Breeze] Age factor: The older you are, the more times your cells need to divide, so cancer mostly breaks out after the age of 40.

[Breeze] Genetic factors: Some people are born with some genetic mutations, which cannot cause cancer, but can increase their risk of getting cancer greatly; congenital and acquired immune defects are also prone to malignant tumors.

[Breeze] Long-term exposure to carcinogenic factors: such as contaminated food, toxic air and radiation make the environment in which DNA is located harsh, which also increase the chance of cancer.

[Breeze] Trauma and local chronic inflammatory irritation: burns, scars, and chronic skin ulcers can also lead to cancer.

[Breeze] Hormonal abnormalities in the body are also one of the factors that induce cancer.

What should people do to prevent cancer in general?

(1) Regular work and rest time: staying up late for a long time is more damaging to the body and prone to various malignant tumors.

(2) Good dietary habits: Try to avoid the intake of stimulating diet, such as reducing the use of pickled, spicy, overheated and processed meat products with too much content, so as to avoid the occurrence of digestive tract tumors.

(3) Quit smoking: Smoking can usually induce cancers in several system organs, commonly in lung cancer, but the incidence of nasopharyngeal cancer, some tumors of the pharynx, esophageal cancer, and even gastric cancer may be more related to smoking, so patients are advised to quit smoking as much as possible in daily life.

(4) Other aspects: Patients should actively prevent or detect and treat early, such as finding smaller lung nodules or gastrointestinal polyps for early intervention, especially gastrointestinal polyps are removed in the early benign stage, which can usually avoid malignant transformation into cancer later.
