Does the human body have oncogenes? Why do some people get cancer and others don't?

We say that everyone has cancer cells, but not everyone will get cancer. What is the reason? Let me talk to you about cancer cells and cancer:

First, let's talk about the generation of cancer cells. Each cell has many genes, usually around 300 to 400. Some positive genes are easy to express, and some negative genes are not easy to express. These genes control the normal function of cells, and oncogenes are actually some genes involved in cell growth, division and differentiation in normal cells, which everyone has. These genes exist in inactive form in normal cells, so they are also called protooncogenes. When proto-oncogenes encounter some external factors, environmental changes and personal living habits. It may eventually evolve and become an oncogene. Oncogenes are quiet under normal circumstances and mutate only when stimulated. It became cancer.

Second, in addition to oncogenes, we also have tumor suppressor genes in our bodies. The tumor suppressor gene is like a child who made a mistake, so the tumor suppressor gene is like a teacher, which will bring the tumor suppressor gene back to the right track in time. If tumor suppressor gene is an uncontrollable cell growth accelerator, then tumor suppressor gene is its brake. This is one of the reasons why some people can't get cancer although they have oncogenes in their bodies, and that is to be controlled by tumor suppressor genes.

Third, everyone has cancer cells, but everyone's physique is different. Acidic physique is easy to get, so it is necessary to regulate body fluids. Cancer cells need conditions to activate it, such as physical aspects such as radiation, chemical aspects such as some toxic chemicals, and biological aspects such as some viruses and microorganisms. Some proto-oncogenes are activated, which may cause some cells to evolve into benign tumors or even malignant cancers. In addition, the same person, after the age of 55, the number of cancer cells decreases, coupled with bad living habits, the greater the chance of getting cancer. This is why old people are more likely to get cancer than young people.

Cancer is not terrible, as long as we have good living habits, early detection and early prevention, everything is under control.
