Unlike early symptoms of cervical cancer such as “abnormal leucorrhea” and “vaginal bleeding”, some patients with cervical adenocarcinoma may have a different symptom – vaginal fluid discharge. Since most of the discharged fluid is watery, many patients may mistake it for “urinary incontinence” and are too ashamed to talk about it, thus delaying the treatment. The number of patients who come to the doctor with “urinary incontinence” as a symptom only to find cervical cancer is increasing every year. This type of cervical cancer is called “cervical adenocarcinoma”, which previously accounted for only about 5% of cervical cancer, but its incidence has been increasing year by year in recent years and has now reached about 20%. There is a difference between vaginal drainage and urinary incontinence caused by cervical cancer. Stress incontinence usually occurs when there is increased pressure such as sneezing, coughing or lifting heavy objects, while vaginal discharge due to cervical adenocarcinoma is constant and very large, often soaking the underwear. Vaginal discharge is an early symptom of cervical cancer, and if it is diagnosed and treated at this time, the survival rate and recovery rate will be much higher. Director Zhang Hongwei reminds that if such a situation occurs, it is important to be alert and seek medical attention as soon as possible. The morphology of cervical adenocarcinoma and cervical squamous carcinoma is different. In cervical squamous carcinoma, polyp-like or cauliflower-like abnormalities usually grow outwardly on the cervix, while in cervical adenocarcinoma, the cancerous part often grows insidiously on the inner side of the cervical canal. Some patients with cervical cancer may have negative TCT and HPV tests. Therefore, cervical examination should also be based on the principle of individualization. For high-risk groups, long-term use of birth control pills or the occurrence of bleeding after intercourse, it is better to adopt the new three-step approach i.e. cytology + HPV + colposcopic pathological histological diagnosis to confirm the diagnosis. Overall, the main causative high-risk factor is the same whether it is squamous or adenocarcinoma, i.e. persistent HPV infection. The difference is that adenocarcinoma is mainly infected with HPV subtype 18, while squamous carcinoma is mainly infected with HPV subtype 16. How to prevent cervical cancer? Firstly, maintain a healthy lifestyle with a balanced diet, proper exercise, no smoking and no drug use; secondly, avoid premature sex and multiple sexual partners; finally, women should undergo cytological screening at least once a year after having sex for early detection of cervical precancer or early cervical cancer.
