What is the difference between cervical cancer and cervical erosion? What should we pay attention to in preventing cervical cancer?

Wang, a white-collar worker in his 30s, had been troubled by excessive vaginal discharge for a long time, which was considered "cervical erosion". After two years of intermittent diagnosis and treatment, the symptoms worsened. Human papillomavirus (HpV) was detected through colposcopy, and cervical adenocarcinoma in situ was found.

Papillomavirus is the main risk factor for cervical cancer. "Cervical erosion" has similar symptoms, and blind treatment can lead to the spread of cancer. Some serious "cervical erosion" is caused by papillomavirus infection and needs observation and treatment, otherwise lesions will occur. It is worth noting that mild, moderate and severe cervical intraepithelial neoplasia lesions are ignored because the symptoms are not obvious and do not affect normal life, but they are one of the biggest hidden dangers of cervical cancer. "Cervical erosion" should be actively and standardizedly treated to find out the cause.

There are five ways to diagnose cervical cancer

1. Cervical smear cytology, also known as vaginal exfoliated cell smear examination, is the main method for screening and early detection of cervical cancer. This method is simple and easy to use, with an accuracy rate of up to 95%.

2. Cervical iodine test: Normal cervical vaginal squamous epithelium is rich in glycogen, and the iodine solution is brown or dark brown. The non-stained area indicates that the epithelium lacks glycogen and may have lesions. Biopsy in the non-stained area can improve the diagnosis rate.

3. For colposcopy, cervical scraping cytology examination grade III and above, and TBS classified as squamous intraepithelial neoplasia, suspicious cancerous areas should be selected for cervical biopsy under colposcopy.

4. Biopsy of the cervix and endocervical canal is a reliable basis for diagnosing cervical cancer and cervical precancerous lesions. The tissue removed should include stroma and adjacent normal tissue. The cervical smear is positive, but the cervix is ​​smooth or the cervical biopsy is negative. Use a small spoon to scrape the endocervical canal and send the scraped material for pathological examination.

5. Cervical conization is suitable for patients with multiple positive cervical smear tests and negative cervical biopsy; or patients with cervical intraepithelial neoplasia in cervical biopsy who should exclude invasive cancer. Cold knife excision, loop electrosurgical excision or cryoelectric excision.

Five key points to prevent cervical cancer

1. Advocate late marriage, fewer births, and better births. Delaying the age of sexual life and reducing the number of births can reduce the incidence of cervical cancer.

2. Actively prevent and treat cervical rot and chronic cervicitis. Pay attention to avoid cervical laceration during delivery. If there is laceration, it should be repaired in time.

3. Pay attention to sexual and menstrual hygiene. Properly control sexual life, avoid sexual intercourse during menstruation and the postpartum period, pay attention to the cleanliness and hygiene of both parties' reproductive organs, and wear condoms during sexual intercourse to reduce and eliminate multiple sexual partners.

4. Men with phimosis or prepuce that is too long should pay attention to local cleaning, and it is best to have a circumcision. This will not only reduce the risk of his wife developing cervical cancer, but also prevent his own penile cancer.

5. For high-risk groups for cervical cancer, including women who have sex too early, too often, give birth too early, too often, too frequently, women who have promiscuous sex, women with multiple sexual partners and unclean sexual history, women in areas with poor sanitary conditions and insufficient sexual health knowledge, women with cervical rot, tear, chronic inflammation, vaginal infection, and women whose spouses have long foreskin or phimosis, special attention should be paid to regular screening. If possible, cervical cancer embolism can be tried for preventive treatment.
