Multiple diagnostic methods for cervical precancerous lesions

Many women do not pay attention to their own hygiene problems, which may cause damage to the uterus, especially the appearance of cervical cancer, which brings a fatal blow to patients and seriously affects their health. Therefore, everyone needs to pay attention to the onset of this disease, effectively regulate themselves, and recover as soon as possible. So, what are the diagnostic methods for female cervical precancerous lesions?

What are the diagnostic methods for female cervical precancerous lesions?

1. Cervical smear cytology is commonly used to screen for cervical cancer. The smear examination must be performed in the transitional zone of the cervix.

2. Iodine test: Apply iodine solution to the cervix and vaginal wall and observe its coloration. Normal cervical vagina and vaginal squamous epithelium are rich in glycogen and are stained brown or dark reddish brown by iodine solution. If it does not stain, it is positive, indicating that the squamous epithelium does not contain glycogen. Scars, cysts, cervicitis or cervical cancer do not stain, so this test is not specific to cancer, but it can determine the site of biopsy and improve the diagnosis rate.

3. The nitrogen laser tumor intrinsic fluorescence diagnostic method is based on the affinity of fluorescein to tumors. If the surface of the cervix appears purple or purple-red, it is positive, indicating the presence of lesions; if it appears bluish-white, it is negative, indicating the absence of malignant lesions.

4. Patients with grade III or above in cervical smear cytology examination or positive tumor intrinsic fluorescence test should be examined under colposcopy to improve the accuracy of diagnosis.

5. Cervical conization: When multiple cervical scraping tests are positive but cervical biopsy is negative, or when the biopsy is carcinoma in situ but invasive cancer cannot be ruled out, cervical conization should be performed. After cervical cancer is confirmed, chest X-rays, lymph node angiography, cystoscopy and colonoscopy are performed according to the specific situation to determine its clinical stage.

What are the types of cervical cancer?

(1) Cauliflower or papillary type: The most common type is an exophytic tumor that is cauliflower-like and often occurs on the lip of the cervix. It has low invasiveness and is often accompanied by necrosis, infection, and bleeding. It is sensitive to radiation.

(2) Infiltrative type: mainly shows infiltrative growth, with little bleeding, but is highly invasive and has poor sensitivity to radiation.

(3) Ulcer type: Less common than the cauliflower type, the cancerous tissue first destroys the surface of the cervix and gradually penetrates into it, causing more damage and forming an ulcer. This type often occurs on the cervical lips and endocervical canal. Necrotic tissue can often be seen. It is prone to infection and is sensitive to radiation.

(4) Nodular type: The least common type, with widespread hypertrophy of the cervix and infiltration mainly into the deep part of the cervix. It is generally as hard as hard rubber or wood and is moderately sensitive to radiation.

Everyone needs to pay attention to the diagnosis of cervical cancer, and in daily life, we must pay attention to reasonable treatment, and also pay attention to conditioning methods, so that it will be more conducive to the recovery of the disease. Usually, you need to pay attention to your physical and mental care, you must pay attention to uterine hygiene, and pay attention to effective health care. I hope everyone pays attention to timely treatment.
