What are the common causes of ovarian tumors

Ovarian malignant tumors do trouble many women in their lives. If the disease is not effectively controlled, it may endanger life safety and bring more serious consequences. Therefore, we should be more proactive in preventing such diseases. Let's learn about the causes of ovarian malignant tumors.

According to a large amount of statistical data, the following factors may be involved:

(1) Living environment and race The incidence of ovarian malignant tumors varies from country to country. The highest incidence is in Northern Europe and North America, while the incidence in my country is relatively low. The incidence in urban women is higher than that in rural women, and the incidence in women with good economic conditions is higher than that in women with poor economic conditions. In terms of race, the incidence in white people is higher than that in other colored people.

(2) Endocrine disorders Ovarian tumors are more common in single, infertile, or fertile women. The incidence of ovarian cancer increases in women with delayed menarche and premature menopause. Severe premenstrual tension, dysmenorrhea, repeated miscarriages, unusual breast swelling, a history of breast cancer, or a history of endometriosis also increase the incidence of ovarian cancer. These endocrine disorders.

(3) Ovulation frequency and number of ovulations. Ovarian ovulation is a negative stimulus to the stroma on the surface of the ovary. Repeated damage and repair may be a high-risk factor for ovarian cancer. According to statistics from Peking Union Medical College Hospital, the incidence of ovarian cancer is likely to increase with increasing ovulation frequency. Full-term delivery, prolonged breastfeeding, and oral contraceptives can reduce the incidence of ovarian cancer because they reduce the number of ovulations.

(4) Genetic factors: About 20% of patients with ovarian malignancies have a family history. There are three hereditary ovarian cancer syndromes, mainly epithelial, which can put some women at extremely high risk of the disease. Women with no family history of ovarian cancer have a lifetime risk of 1/70. If one first-degree relative is ill, the risk increases to 5%; if two first-degree relatives are ill, the risk is 7%; if there is a first-degree relative with hereditary ovarian cancer syndrome, the risk is as high as 50%, and the risk increases with age.

Through the above article, we have learned the causes of ovarian malignant tumors. Experts remind us that it is indeed necessary to understand the causes of its occurrence, because only by understanding these can we avoid inducing factors and do a good job in preventing ovarian malignant tumors. In addition, after becoming ill, we must also receive symptomatic treatment according to the cause of the disease.
