How many years does cervical cancer usually develop?

Cervical cancer is indeed a gynecological disease that can cause great harm to women's bodies, so every woman should pay attention to cervical cancer. The main cause of cervical cancer is infection with papillomavirus. Therefore, in order to prevent the occurrence of cervical cancer, it is necessary to prevent papillomavirus infection. However, the development process of cervical cancer is also gradual. So how many years does it usually take for cervical cancer to develop?

How long does it take for cervical cancer to develop?

I believe that everyone knows the impact of cervical cancer on female friends. Many patients do not know when they have cervical cancer. In fact, the formation of the disease is not overnight, just as we say that the ice is not formed in a day, and the same is true for tumor diseases. So how long does it take for cervical cancer to form?

Cervical cancer seriously endangers women's healthy life and is one of the killers of women's health. Cancer is the result of many factors acting together. But cancer does not exist from the beginning. Its formation goes through a process, and the same is true for cervical cancer.

The formation of cervical cancer goes through a process. The time it takes for cervical cancer to develop from mild to moderate to severe is about 10 years on average.

Women should go to the gynecological hospital for regular check-ups, such as once a year, or even once every 3 to 5 years. It is possible to detect lesions, which can completely block the development of cancer and eliminate the tumor in the precancerous stage.

Early treatment of cervical cancer is very important, and early prevention and early detection of cervical cancer are very important. It takes about ten years for cervical cancer to develop, which is very beneficial for the prevention of cervical cancer. If we discover cervical cancer within these ten years, it will be of great value for the treatment of cervical cancer.

Regular examination is a very good way to detect lesions. Modern high-end scientific and technological means, PET-CT, has a very good effect on the examination of many lesions. Moreover, PET-CT can detect lesions half a year in advance, giving us the opportunity to kill the lesions in the bud, grasping the best treatment opportunity for cervical cancer treatment and gaining the maximum time.

What are the methods for cervical cancer screening?

As long as a woman starts having sexual activity, she is likely to be infected with HPV (human papillomavirus, the main cause of cervical cancer), so she should undergo regular cervical cancer screening every year after having sexual activity. How to screen for cervical cancer? Cervical cancer screening should adopt a "three-step" procedure of cervical cytology or high-risk HPV DNA testing, colposcopy, and cervical biopsy, and the diagnosis is based on histological diagnosis.

1. Cervical cytology examination

It is a basic method for early cervical cancer screening and an essential step in diagnosis. Compared with high-risk HPV testing, cytology has high specificity but low sensitivity. Screening should begin 3 years after the start of sexual activity, or after the age of 21, and be reviewed regularly.

2. High-risk HPV DNA testing

Compared with cytology, it has higher sensitivity but lower specificity. It can be used in combination with cytology for cervical cancer screening. It can also be used to triage abnormal cytology examinations. When the cytology is atypical squamous cells of undetermined significance (ASCUS), high-risk HPV DNA testing is performed. Those with positive results undergo colposcopy, and those with negative results undergo cytology examination after 12 months.

3. Colposcopy

If the cytology examination shows atypical squamous cells (ASCUS) and the high-risk HPV DNA test is positive, or if it is low-grade squamous intraepithelial lesion or above, a colposcopy should be performed.

4. Cervical biopsy

Any lesion visible to the naked eye should be biopsied at one or more points. If you need to understand the pathological changes of the cervical canal, endocervical scraping should be performed.
