Is cancer an infectious disease?
Is cancer also an infectious disease? Don’t worry about people around you, cancer is generally not contagious.
From a clinical perspective, infectious diseases are diseases that can be transmitted by various pathogens from person to person, animal to animal, animal or person.
What, so who has cancer? Then we must stay away and stop infecting us!
In life, people are always accustomed to judging things by what they see and hear with their naked eyes. When faced with diseases that scare oneself, one will also think of contagion. This is the psychological characteristic of human beings. It is not sad to have such thoughts. The sad thing is that you haven’t fully understood a certain disease, you make a wrong judgment and spread this kind of speech!
Is cancer really contagious? First of all, everyone must understand what an infectious disease is!
From a clinical perspective, infectious diseases are diseases that can be transmitted by various pathogens from person to person, animal to animal, animal or person. In other words, the characteristics that infectious diseases must have are pathogens, transmission channels and infectiousness, susceptible populations, and epidemiological characteristics, so that they can form a chain of infection!
For example, the new type of coronary pneumonia that broke out in early 2020 is a typical infectious disease!
Cancer is obviously not an infectious disease!
Cancer is actually a genetic disease. Cells in the human body are affected by various carcinogenic factors, such as genetic susceptibility genes, inherited tumor genes, and exposure to acquired carcinogens. Cell genes begin to mutate and eventually form cancer cells. Cancer cells do have the characteristics of spreading and metastasis in the body, but this has nothing to do with cancer cell infection!
Because cancer cells have the ability to live forever and proliferate indefinitely after they break away from normal cell growth regulation, a mutated cancer cell can divide and develop into a small cancer. The structure of cancer cells is very loose and can secrete special substances. As a result, cancer cells can not only destroy the surface of surrounding tissues and organs, but also metastasize with the circulatory system!
As long as the person is still alive and the immune system cannot identify and kill cancer cells, they can achieve the goal of symbiosis and immortality with the human body. However, once cancer cells are separated from the human body, lack of nutrient supply, or the patient dies, they will also follow the path of destruction, and will not be transmitted to others in other ways!
Therefore, there is no need to worry about the spread of cancer if you contact with cancer patients. Let alone eating and living together, even if you have sex with cancer patients, you will not be infected. And after a female cancer patient becomes pregnant, cancer cells will not be transmitted to the baby through the placenta and umbilical cord. The real cause of the cancer family outbreak is actually hereditary genes, a common living and eating environment!
However, although cancer cells are not contagious, pathogens related to cancer may be contagious!
Clinically, a number of cancer-related pathogens have been identified, such as hepatitis B virus infection, high-risk hpv infection, and Helicobacter pylori infection. Long-term repeated viral or bacterial infections can cause chronic diseases to appear, cause organ cell damage, division, and immersion in inflammatory reactions. If you do not treat yourself in time, cancer may occur later!
In addition, after being infected with HIV, although it will not directly develop into cancer. However, when the patient enters the symptomatic period, HIV will continue to destroy the autoimmune function, resulting in severe damage to the immune system or loss of immunity. The immune system is unable to recognize and eliminate the mutated cells, and the chances of patients with various cancers will increase!
Therefore, instead of worrying about the spread of cancer, it is better to focus on the spread of pathogens. To prevent the spread of pathogens, what we can do is to live scientifically, maintain healthy, regular sexual habits, have a regular sexual partner, and avoid going to irregular microsurgery or dental hospitals, so that we can really prevent cancer
