Three high-tech technologies help you diagnose cervical cancer

The incidence of cervical cancer has been increasing in recent years, which has endangered the lives of women. Every year, tens of thousands of women lose their lives due to cervical cancer. In fact, if cervical cancer can be discovered and treated in time, the chance of cure is very high. Therefore, if women have discomfort and suspect that they have cervical cancer, they must go to the hospital for regular examination.

Here are three new technologies to help you diagnose cervical cancer:

1) Cervical smear cytology examination:

It is the main method for detecting cervical precancerous lesions and early cervical cancer. Because the cervix is ​​exposed at the top of the vagina, it is easy to observe and sample. Therefore, in clinical practice, cervical cell scraping examination is routinely performed as a screening method for married women during gynecological examinations or cancer prevention surveys. This examination method can greatly increase the positive diagnosis rate of early cervical cancer to more than 90%.

2) Iodine test:

Normal cervical or vaginal squamous epithelium contains abundant glycogen, which can be dyed brown by iodine solution, while endocervical columnar epithelium, cervical erosion and abnormal squamous epithelium have no glycogen and therefore do not stain. In clinical practice, after exposing the cervix with a vaginal speculum, wipe off the surface mucus and apply a 2% iodine solution directly to the cervical and vaginal mucosa. The unstained area is positive. If an abnormal iodine-negative area is found, a biopsy can be taken from this area for pathological examination.

3) Biopsy of cervix and endocervical canal:

Examination is an important part of diagnosis, but biopsy is the most reliable basis for diagnosing cervical cancer. When the cervical scraping cytology examination is a smear of grade III to IV or above, if the cervical biopsy is negative, four-point biopsy should be taken at 6, 9, 12 and 3 points at the junction of the cervical squamous column, or multiple tissues should be taken from the unstained area of ​​iodine test and suspected cancerous sites, and sliced ​​for examination, or a small scraper should be used to scrape the cervical canal and send the scraped material for pathological examination.
