UV and radioactive radiation
This radiation can cause DNA damage, which can lead to mutations and uncontrolled cell growth. The sun's UV rays can directly damage the skin and mucous membranes and increase the risk of certain types of cancer, which can also manifest themselves in the ENT area. In addition, exposure to radioactive radiation, whether through occupational exposure, frequent medical radiation treatments or environmental disasters, can also lead to DNA damage. Protective measures are therefore crucial to reduce the risk of ENT cancer.
Poor oral hygiene
If you do not care for your mouth properly, bacteria, viruses and other harmful substances can accumulate in the mouth and throat. These can cause inflammation and damage to the oral mucosa. This is associated with an increased risk of precancerous lesions and cancer precursors.
Pronounced immunodeficiency (e.g. after transplants)
An intact immune system plays a crucial role in fighting abnormal cells and preventing the development of cancer. If the immune system is weakened, e.g. after organ transplants or in the case of certain diseases such as HIV/AIDS, cancer cells have a greater chance of growing unhindered. In addition, viruses such as the human papillomavirus (HPV) and the Epstein-Barr virus (EBV) can have a greater impact on a sensitive immune system. These viral infections are associated with the development of ENT cancers such as laryngeal cancer and nasopharyngeal carcinoma.
Chronic injuries to the mucous membrane
Persistent inflammation and cell damage caused by chronic injury to the mucous membrane in the ENT area can promote cell growth and division. This can lead to the development of precancerous lesions and ultimately to cancer. In the mouth and throat area in particular, chronic injuries to the mucous membrane can increase the risk of cancers such as oral cavity and pharyngeal carcinomas.
