Safety period: Why is the safety period called safety when it is not safe?

Cervical cancer usually does not cause low back pain in the early stages. Low back pain may be a symptom of the disease progressing to the middle and late stages. Early symptoms of cervical cancer mainly include contact bleeding, abnormal vaginal discharge, abnormal menstruation, etc. As the tumor grows or metastasizes, it may compress nerves or invade surrounding tissues, causing back pain. It is recommended to perform regular cervical cancer screening and seek medical attention promptly if abnormal symptoms occur.

Early symptoms of cervical cancer are mostly limited to the reproductive system. Common manifestations include vaginal bleeding after sexual intercourse or gynecological examination. The blood may be bright red or dark brown, and the amount of bleeding is usually small. Some patients may experience white or bloody vaginal discharge with a peculiar odor. Menstrual cycles may be shorter, longer, or heavier. These symptoms can easily be ignored or mistaken for common gynecological inflammation, leading to delayed diagnosis and treatment.

When cervical cancer progresses to the intermediate and advanced stages, the tumor may invade parametrial tissues or metastasize to distant sites. If the tumor compresses the pelvic nerves or invades the lumbar spine, it may cause persistent lumbosacral pain that can radiate to the buttocks or lower limbs. At the same time, it may be accompanied by systemic symptoms such as lower limb edema, difficulty urinating, weight loss, and fatigue. At this time, the disease is already at an advanced stage and treatment becomes more difficult.

Regular cervical cytology and HPV testing are key to detecting early-stage cervical cancer. It is recommended that women over 21 years old or with a history of sexual intercourse should be screened every 1-3 years. Maintaining a single sex partner, getting the HPV vaccine, and avoiding smoking can help prevent cervical cancer. When abnormal vaginal bleeding or discharge occurs, you should seek medical attention as soon as possible and obtain a clear diagnosis through colposcopy biopsy. Early treatment can lead to a better prognosis.
