Ovarian tumors are common tumors of the female genitalia and have various natures and forms, i.e., unilateral or bilateral, cystic or solid, benign or malignant, among which cystic is common and has a certain proportion of malignancy. The most characteristic feature of intra-abdominal masses of less than moderate size, without complications or malignancy, is their mobility, often being able to push from the pelvis to the abdominal cavity. In malignant or inflammatory cases, the mass has restricted mobility, pressure pain, and even symptoms of peritoneal irritation and ascites. What are the causes of ovarian tumor: 1. Genetic factors According to statistics, 20%-25% of ovarian tumor patients have family history. Endocrine factors Ovary is an important organ for ovulation and secretion of gonadal hormones, and ovarian tumors mostly occur in reproductive age. The basic pathophysiological change of many patients with ovarian cysts and polycystic ovary syndrome is that the ovaries produce too much androgens, and the excessive production of androgens is the result of the abnormal function of various endocrine systems in the body. 3, Lifestyle factors Long-term dietary structure, poor lifestyle habits, and excessive psychological stress can lead to physiological ovarian cysts and true ovarian masses. 4.Environmental factors Pollution of food, such as vegetables and other plant growth hormones used, such as lean meat extract-type hormone ingredients in formula feeding of livestock and poultry. In recent years, with the improvement of living standards and changes in dietary habits in China, and the abuse of hormonal drugs and tonic products such as breast enlargement, weight loss, and slowing down aging by some young and middle-aged women, ovarian tumors are becoming more prevalent and younger, which may also be related.
