Is laryngeal cancer hereditary?

Laryngeal cancer is hereditary to a certain extent. The familial inheritance of laryngeal cancer is caused by chromosomal aberrations in the human body. Each cell in the normal human body has 46 chromosomes. Various carcinogenic factors can cause chromosomal aberrations, making the number and shape of chromosomes different from those of normal cells. This chromosomal aberration can sometimes be inherited by offspring, making the next generation likely to develop cancer.

In addition, people who are likely to develop cancer do not necessarily get cancer, but they just have a higher chance of getting cancer than ordinary people. Experts believe that the occurrence of cancer is determined by internal and external factors. Cancer constitution only has certain internal factors. If external carcinogenic factors such as radiation and smoking are added, cancer will occur.

People with a family history of laryngeal cancer will inherit chromosomal abnormalities, which can lead to some immune function defects, thereby reducing the body's resistance, increasing the sensitivity to carcinogens, and increasing the risk of disease.

The genetic tendency of laryngeal cancer only shows that people with a family history of the disease have a higher risk of disease than ordinary people, but it does not necessarily lead to the disease. Any kind of cancer, including laryngeal cancer, is the result of the combined action of internal and external factors. Internal factors need to be stimulated by external factors to work. In the occurrence of laryngeal cancer, external factors such as radiation exposure, viral infection, and smoking play a more important role. These factors lead to strong stimulation of the larynx, causing cells to actively respond to these stimuli. Susceptible constitutions are more susceptible to carcinogens and induce laryngeal cancer.

Although laryngeal cancer has a certain genetic factor, laryngeal cancer in the previous generation does not necessarily lead to the disease in the next generation. Expectant mothers do not need to worry about the disease being passed on to their offspring and terminate their pregnancy. As long as they take proper precautions and pay attention to screening, the risk of disease can be completely reduced.

Therefore, not all laryngeal cancer is hereditary. People with a family history of laryngeal cancer should realize that although they may develop laryngeal cancer due to heredity, it does not mean that they will definitely get laryngeal cancer, and they should avoid unnecessary fear. On the other hand, they should pay more attention to cancer prevention and strive for early detection, early diagnosis and early treatment.
