Is rectal cancer metastasis contagious?

Rectal cancer is caused by the malignant transformation of rectal tissue cells. The cause of rectal cancer is still unclear, and it has a lot to do with the living environment and living habits. Rectal cancer seriously affects the patient's physical and mental health, and also brings a lot of inconvenience to the patient's life and work. Many people worry about whether rectal cancer is contagious. So let's take a look at whether rectal cancer is contagious?

Among the factors that induce cancer, 80% are related to environmental factors. Although some cancers, such as liver cancer, stomach cancer, and nasopharyngeal cancer, are related to viral infections, there is no case that proves that cancer is indeed contagious, and the incidence of cancer among medical personnel engaged in tumor diagnosis and treatment is not high in the survey.

Cancer cells have four ways of metastasis, namely direct spread, lymphatic metastasis, blood metastasis and implantation metastasis. They cannot be transmitted by other ways. Normal skin will not be infected if it comes into contact with it. However, when the skin is damaged, it will be implanted if it comes into contact with cancer cells. In this way, the cancer cells are metastatic, not transmitted to others. Therefore, there is no evidence to show that rectal cancer can be transmitted.

Viruses are contagious, but the infectivity of different viruses varies. After viral infection, only 1% to 1% of people will develop clinical symptoms, while more people will not develop symptoms and are in a latent infection state. Whether or not a person develops symptoms after viral infection is closely related to the body's defense function. If the body's defense function is strong, even if there is a viral infection, the person may not develop the disease for life. It has been determined that more than 100 viruses can cause more than 30 types of tumors in animals. Some viruses can also cause human tumors. In this way, there is an objective material basis for the possibility of tumor transmission. Viruses or such virus particles have also been found in human Burkitt's lymphoma, nasopharyngeal carcinoma, breast cancer, leukemia, cervical cancer, and melanoma.

The above is an introduction to whether rectal cancer is contagious. Through the above content, I believe everyone has a certain understanding of rectal cancer. Once there are symptoms of rectal cancer, you should go to a regular hospital for treatment in time to avoid delaying the best period of treatment.
