Is cervical precancerous lesion serious?

Patients with cervical precancerous lesions generally do not show obvious symptoms, or only have general cervicitis symptoms, such as increased leucorrhea. Some patients also complain of bloody leucorrhea or a small amount of vaginal bleeding after sexual contact. Gynecological examinations can show that the cervix is ​​smooth, without obvious inflammation, or with cervical congestion or erosion, with varying degrees of erosion. The following will introduce the hazards of this disease.

1. Vaginal bleeding.

Irregular vaginal bleeding is the main symptom of patients with cervical precancerous lesions, especially vaginal bleeding after menopause should be paid more attention. The amount of vaginal bleeding can be more or less. Vaginal bleeding is often caused by rupture of tumor blood vessels. Especially for esophageal tumors, bleeding symptoms appear earlier and the amount is larger. If bleeding occurs frequently, excessive blood loss can lead to severe anemia.

2. Increased vaginal discharge.

This is the main symptom of patients with cervical precancerous lesions. It often occurs before vaginal bleeding. Initially, vaginal discharge may not have any odor. As the tumor grows, the tumor becomes infected and necrotic, and the discharge increases, such as rice washing water or mixed with blood, and has a foul odor. When the tumor spreads upward and involves the endometrium, the discharge is blocked by the cervical cancer tissue and cannot be discharged, which may form intrauterine fluid or intrauterine pyometra. The patient may experience symptoms such as lower abdominal discomfort, lower abdominal pain, back pain, and fever.

3. Frequent, urgent and painful urination.

When the cancer spreads forward, it can invade the bladder, and the patient will experience prolapse and frequent urination, urgency, pain, and hematuria. It is often misdiagnosed as a urinary tract infection and delayed diagnosis. In severe cases, a bladder-vaginal fistula may form. The cancer spreads backward and can invade the rectum, causing symptoms such as prolapse, difficulty defecating, tenesmus, and blood in the stool. Further development may lead to vaginal-rectal fistula. Distant metastasis may occur in the late stage of the disease. Different sites of metastasis will produce different symptoms. The most common is supraclavicular lymph node metastasis, where nodules or lumps appear. Tumor infiltration can spread to distant organs through blood vessels or lymphatic system, resulting in metastatic lesions in corresponding sites and corresponding symptoms.

4. Pain.

This is a symptom of advanced cervical precancerous lesions. The cancer extends along the adjacent tissues, invades the pelvic wall, and compresses the peripheral nerves. The clinical manifestation is persistent pain in the sciatic nerve or one side of the sacral or iliac region. The tumor compresses or erodes the ureter, and the ureter is narrowed and blocked, leading to hydronephrosis, which manifests as one side of the waist pain or even severe pain, and further develops into renal failure and even uremia. The invasion of the lymphatic system leads to obstruction of the lymphatic vessels, which hinders the reflux and causes symptoms such as edema and pain in the lower limbs.
