Epithelioid malignancy, usually referred to as malignant epithelial tumor, is one of the types of cancer. At present, the etiology and pathogenesis are not clear, but it may be related to genetic factors, environmental factors and immune factors.
1. Genetic factors: malignant epithelial tumors usually have certain family aggregation, which is considered to be related to genetic factors, especially for patients whose immediate family members have malignant epithelial tumors, the chances of occurrence of malignant epithelial tumors are higher than that of normal people.
2. Environmental factors: for those who are engaged in chemical work, they may be exposed to more chemical carcinogens in their daily life, which may induce patients to have low immunity and increase the incidence of malignant epithelial tumors.
3. Immunity factors: for patients with congenital or acquired immunity defects, it is easy for malignant epithelial tumors to occur, the main reason is that tumors can escape the surveillance of the immune system and destroy the immune system of the body.
Patients with epithelioid malignant tumors should cooperate with doctors for treatment as soon as possible after diagnosis, so as not to affect the prognosis.
