Cervical cancer occupies the first place among cancers of female reproductive organs, and its incidence rate has obvious regional differences. The average age of onset of cervical cancer patients in China is most often 40-50 years old, with another peak occurring between 60 and 70 years old, and rare before 20 years old. Fallopian tube tumors are rare, and benign is more rare than malignant. Most of them are secondary cancers, accounting for 80-90 of tubal malignant tumors. Most of the primary foci are located in the ovary and uterine body, but they can also be metastasized from the opposite fallopian tube, cervical cancer, rectal cancer, breast cancer, and so on. Metastasis is mainly through lymphatic tract. Symptoms, signs and treatment depend on the primary site and the prognosis is poor. Endometrial cancer, also known as uterine body cancer, is a common malignant tumor in gynecology, second only to cervical cancer, with an average age of about 60 years, mostly seen in older women. It is a hormone-dependent disease and is associated with high estrogen levels. Choriocarcinoma Choriocarcinoma (choriocarcinoma) is the most malignant trophoblastic tumor with the highest degree of malignancy. It is characterized by the loss of the original structure of chorionic villi or chylomicrons and the invasion of trophoblast cells into the myometrium, which not only causes serious damage such as local necrosis and bleeding, but also metastasizes to other organs or tissues through bloodstream at an early stage, leading to death. How to detect gynecological malignant tumors in early stage According to the survey, most of the gynecological malignant tumors do not have obvious symptoms in the early stage, and as long as they are detected and treated early, they can also have a high cure rate. The early cure rate of cervical cancer can reach 90%, and even young women under 20 years old often have ovarian germ cell cancer and cervical cancer. endometrial cancer that occurs under 40 years old is mostly in those whose ovaries do not ovulate. For early detection of cancer, the first step is to understand some symptoms of cancer and to have regular checkups, such as cervical cancer screening for early detection of cervical cancer, or further colposcopy for more accurate diagnosis by cutting the suspected area directly. Pelvic examinations are also important for early detection of uterine and ovarian tumor lesions. Ultrasound examination can further confirm the nature, size and location of the tumor, and is especially beneficial for middle-aged obese women. Who especially needs cervical cancer screening? Early stage cervical cancer mostly occurs at the age of 33-38. The following factors are considered as high risk factors for the development of cervical cancer: 1. early sexual intercourse; 2. many sexual partners; 3. human papilloma virus infection; 4. people of low living class. Who should be especially screened for endometrial cancer? Endometrial cancer is more likely to occur in women aged 50-59, especially those with the following factors: 1. obesity (3-10 times more likely); 2. not having children (2-3 times more likely); 3. menopause after age 52 (2.4 times more likely); 4. diabetes mellitus; 5. hypertension; 6. arteriosclerosis. Who should be especially screened for ovarian cancer? Ovarian cancer is more likely to occur in women aged 50-59 years old. Industrialized society, physical and chemical environmental stimuli have increased ovarian cancer year by year. Therefore, in an industrialized society, every woman should not neglect ovarian screening.
