Cervical cancer, also known as invasive cervical cancer, is the most common gynecologic malignancy. The age distribution of patients is bimodal, 35-39 years old and 60-64 years old, with an average age of 52.2 years. Since cervical cancer has a long precancerous stage, cervical cytology examination can enable early diagnosis and early treatment of cervical cancer. So what are the symptoms of early cervical cancer? The most common symptom is irregular vaginal bleeding, including vaginal bleeding during: 1. non-menstrual vaginal bleeding (tumors bleed easily); 2. bleeding or pain during intercourse; 3. bleeding at any time after menopause. Other symptoms of early cervical cancer include: 1) unpleasant vaginal discharge; 2) pelvic pain and back pain (may be due to cancer involving nerves or bones); 3) bleeding or painful urination (may be due to cancer involving the urinary system); 4) swollen feet (may be due to cancer involving the lymphatic system); 5) general fatigue and weight loss.
