What are the causes of ovarian cancer

The specific causes of ovarian cancer are not very clear. Generally speaking, it is mainly related to infertile women or the lack of fertility. Especially when ovulation drugs are used, the chance of ovarian cancer will be greatly increased. Of course, there are some other causes. The following is a detailed introduction:

1. Genetic and family factors. About 20-25% of ovarian cancer patients have a family history. The so-called familial clustering of ovarian cancer refers to a high incidence in the whole family, mainly epithelial cancer. 5-14% of women with Pierce-Jeghers syndrome develop ovarian cancer, and basal cell nevus syndrome often coexists with ovarian fibrosis.

2. Environmental factors: The high incidence of ovarian cancer in industrially developed countries may be related to the high cholesterol content in the diet.

3. Endocrine factors: The chance of breast cancer or endometrial cancer complicated with ovarian cancer is 2 times higher than normal. All three occur in hormone-dependent women. Among ovarian cancer patients, the number of pregnancies is low and the proportion of non-pregnant women is high, indicating that pregnancy seems to have an antagonistic effect on the occurrence of ovarian cancer. Breastfeeding and ovulation stop during pregnancy, reducing damage to the ovarian epithelium.

4. Viral factors.

5. Smoking by women (directly or indirectly) is considered one of the causes of ovarian cancer.

6. Excessive X-ray exposure.

7. Chemical carcinogenic factors, etc.

Clinical studies have shown that the biggest cause of ovarian cancer is genetic factors, so this disease is very harmful, and people with a family history of ovarian cancer are advised to take ovarian cancer prevention seriously. The ultimate goal of preventing ovarian cancer is mainly through some special methods.
