Many women do not understand screening for breast and cervical cancer. It is the use of advanced screening to detect whether a person has a general gynecological condition or cancer by screening out people who think they are healthy and who may have a problem. The two cancers refer to cervical cancer and breast cancer. Screening for two cancers means that advanced screening methods are used to detect whether the subject has cancer or a general gynecological disease. The purpose of two cancers screening is to detect and examine these two types of cancers that are harmful to women’s health as early as possible. Early detection, early diagnosis and early treatment are achieved. Which two cancers are screened? What is the significance? Cervical cancer is one of the common gynecological malignancies Cervical cancer is the second most common cancer in the female reproductive system after breast cancer. There are about 131,500 new cases in China every year, accounting for 28.8% of the total number of new cases of cervical cancer in the world; about 290,000 women die of cervical cancer worldwide every year, of which about 50,000 are in China. And rural areas are higher than urban areas, and the peak age of incidence is 40-70 years old. With the increase of STD incidence, the incidence of cervical cancer in young women has a rising trend, with an annual growth rate of 2%-3%. The incidence and mortality rate of cervical cancer in China are gradually increasing and obviously tend to be younger; it is most concentrated among 36 to 50 years old, accounting for about 57% of the number of patients, especially among women aged 41 to 47 years old. In the 1970s, cervical cancer accounted for only 0.5% of young women under the age of 30, but after the 1990s, the proportion of cervical cancer among young women aged 30 rose to 15%-20%. Cervical cancer is hidden and difficult to be detected at the first time Because of the deep physiological anatomical location of the cervix, patients often cannot be detected through self-examination when it becomes cancerous, resulting in many cervical cancer patients being asymptomatic until the middle and late stages of the disease, which leads to the spread of cancerous tissues. Therefore, in order to detect cervical cancer at an early stage, it is necessary to conduct gynecological screening with the help of medical personnel. In order to raise the awareness of cervical cancer among women in Beijing and to achieve early detection, diagnosis and treatment of cervical cancer, cervical fluid-based thin layer cytology (TCT) is a more advanced diagnostic method. Breast cancer is one of the most common malignant tumors in women, according to statistics, the incidence rate accounts for 7-10% of all kinds of malignant tumors in the body. Its incidence is often related to heredity and is higher in women between the ages of 40-60, before and after menopause. Only about 1-2% of breast patients are male. It is a malignant tumor that usually occurs in the glandular epithelial tissue of the breast. It is one of the most common malignant tumors that seriously affects women’s physical and mental health and even endangers their lives. The main symptoms are: breast lumps, breast pain, nipple overflow, nipple changes, skin changes, and enlarged axillary lymph nodes. As long as women can have a strong awareness of cancer prevention, comprehensively understand and master these knowledge, and do self-examination seriously, with the improvement of medical care, I believe cancer is by no means an incurable disease.
