Is it contagious after bowel cancer surgery

Intestinal cancer is one of the most common malignant tumors, with the highest incidence in the 40-50 age group. In my country, its incidence and mortality are lower than those of gastric cancer. In recent years, data from various regions show that with the improvement of people's living standards and changes in dietary structure, its incidence rate has been increasing year by year. People can't help but ask, is intestinal cancer contagious after surgery?

Colon cancer is not contagious because cancer cells are not contagious, but some viruses that cause cancer are contagious, such as the hepatitis B virus that causes liver cancer, Helicobacter pylori that causes gastric cancer, and the Epstein-Barr virus that causes nasopharyngeal cancer.

How cancer is produced Cancer is a new organism in the human body (something that should not exist under normal circumstances). This new organism is composed of a group of cancer cells that develop freely without following physiological needs. Cancer cells do not have the functions of normal cells. Due to their rapid and irregular growth, they not only consume a large amount of nutrients in the human body, but also destroy the tissue structure and function of normal organs.

There is a gene that can cause cell cancer in human cells. Under normal circumstances, oncogenes are not only harmless to the human body, but also play an important role in cell growth. When oncogenes are repeatedly exposed to external carcinogenic factors (such as radiation, viruses, chemicals, etc.), the static oncogenes in the cells are activated, the gene structure mutates, and the normal cell functions rebel, so the cells become cancerous. In addition to eroding and spreading to the surrounding areas in an invasive growth manner, cancer cells can also spread to other organs and tissues through other pathways, causing these tissues and organs to develop the same tumor. This situation is called "metastasis."
