How is squamous cell carcinoma caused?

Cancer includes squamous cell carcinoma, squamous cell carcinoma is a name for pathological classification of tumors. Tumors, especially cancers, are divided into squamous cell carcinoma, adenocarcinoma, lymphoma, etc. Squamous cell carcinoma occurs mainly due to mutations in oncogenes in the human body, causing tumor cells to differentiate and become malignant. The human body itself has carcinogenic genes. Under normal circumstances, human immunity can control the mutation of carcinogenic genes. However, under various circumstances, especially under the influence of external factors, human immunity cannot monitor or control the occurrence of carcinogenic genes. Finally, through a series of physiological and pathological processes, some changes or occurrences of squamous cell carcinoma are shown. Cancer-causing genes are normally suppressed or monitored by the body's immune system and do not produce tumor cells. However, various factors, including physical decline or severe mental trauma and other diseases, or external food, water and air pollution, can trigger the further development of carcinogenic genes, so that the immune system is suppressed, which may produce cancer lesions.
