What are the main symptoms of cervical precancerous lesions?

Cervical precancerous lesions are a gynecological disease that can be detected early. In developing countries, cervical precancerous lesions are the number one common tumor, so understanding the early symptoms of uterine cancer is of great significance for its treatment.

1. Early symptoms of cervical precancerous lesions

(1) Vaginal bleeding manifests itself as contact bleeding (during sexual intercourse or bimanual examination) in the early stage, followed by intermittent and irregular bleeding. Late-stage cancer erodes large blood vessels and can cause heavy bleeding. Generally, exophytic cancers bleed earlier, while endophytic cancers bleed later.

(2) Increased vaginal discharge In the early stages, due to the presence of cancer, the cervical glands are stimulated to over-secrete, producing mucous leucorrhea. In the late stages, the cancer tissue is necrotic and secondary infection occurs, and the leucorrhea becomes turbid, rice soup-like or pus-like, bloody, and has a foul odor.

(3) Pain is a late-stage symptom. When the tumor infiltrates the paracervical tissue and affects the pelvic cavity, obturator nerve, and sacral nerve, it can cause severe persistent lumbar and sciatica pain. Extensive pelvic lesions and obstruction of venous and lymphatic return can lead to swelling and pain in the lower limbs.

2. Early symptoms and signs of cervical precancerous lesions

(1) A full-body examination is performed to determine whether there are any distant metastatic lesions; attention should be paid to whether the iliac fossa, inguinal, and supraclavicular lymph nodes are enlarged; whether the kidneys are enlarged and whether there is any percussion tenderness in the renal area.

(2) During gynecological examination, pay attention to whether the cervix is ​​infiltrated. When invasive cancer develops, the cervix may show the following different manifestations:

① Erosive type: There are coarse granular erosion areas around the external cervical os, which are dull and brittle, easily bleed when touched, or may ulcerate.

② Cauliflower-shaped (exophytic) cancer grows outward, initially presenting as a polyp-like or papillary protrusion, then developing into a cauliflower-shaped protrusion, protruding into the vagina, being brittle and prone to bleeding

Not paying attention to menstrual hygiene, sexual disorders and some cervical precancerous lesions will increase the possibility of uterine cancer, so an important measure to prevent cervical precancerous lesions is to actively treat these chronic diseases. Start from childhood, if you don't treat minor illnesses, major illnesses may come to you.
