Is cervical precancerous lesion cancer?

Everyone must be familiar with cervical cancer. So, is cervical precancerous lesion cancer? Cervical precancerous lesion refers to the lesion that occurs in the area before cancer occurs and thus causes cancer. Cervical precancerous lesion is atypical hyperplasia of the cervix. So, is cervical precancerous lesion cancer?

●Cervical precancerous lesions (CIN) occur in women who have sexual activities. Most cervical diseases can be detected and treated at the precancerous lesion stage through liquid-based cytology testing (TCT).

●The diagnosis of cervical disease requires a three-pronged approach using TCT, HPV testing, and colposcopy. Colposcopy is not the first choice.

"Doctor, isn't my cervix smooth? Isn't smooth normal? Why do you write that you are not satisfied with the colposcopy image? Did I do it in vain? I don't have cancer, do I?" "Doctor, do I need to do cervical screening if my cervical erosion is serious?" "Doctor, what does my CIN2-3 test result mean? The Internet says that CIN is a precancerous lesion, so is my CIN2-3 cancer?" Gynecologists encounter patients who do cervical screening almost every day, and they come to ask questions with the report. However, many patients have many cognitive misunderstandings about cervical diseases, or even know nothing about them.

Do you know how to read the cervical screening report? What are the "specified actions" that must be done in the cervical screening program? What inspection orders cannot be wrong? The reporter invited cervical specialist clinic experts to answer your questions one by one.

Cervical intraepithelial neoplasia (CIN) is not cancer

"What does my test result CIN2-3 mean?" 26-year-old Xiaolan asked the doctor nervously while holding the cervical biopsy pathology results. "The Internet said that CIN is a precancerous lesion. Is my CIN2-3 cancer?" "CIN can be treated, it is not cancer!" The expert said that fortunately Xiaolan had a cervical screening and found the existing precancerous lesions early, otherwise it would be too late to wait until the body was abnormal. "Xiaolan needs to have a cervical conization surgery. The surgery is only a local removal of the cervix, which will not affect fertility. Most people will get better after treatment. But a small number of people will have residual or recurrence after surgery, so regular check-ups are required."

According to the expert, "CIN" is the abbreviation of "cervical intraepithelial neoplasia", which can be commonly referred to as "cervical precancerous lesions", which occur in women who have sexual life. "Cervical intraepithelial neoplasia is not cancer, but it is closely related to cervical cancer." She introduced that CIN is usually divided into three levels, CIN1, 2, and 3. Strictly speaking, CIN1 is not a precancerous lesion. About 70% of CIN1 will disappear naturally, while CIN2 and 3 have a much greater chance of developing into cervical cancer than CIN1, so they are also called precancerous lesions. "Cervical cancer is the only gynecological tumor that can be detected and prevented early through physical examinations. As long as you pay attention to regular cervical screening, most of them can be found and treated at the precancerous lesion (CIN) stage." The expert said that the treatment of precancerous lesions does not require hysterectomy and does not have much impact on future fertility.

Two out of ten sexually active women are infected with HPV

Xiaolan was confused: "Why did I get this disease? I'm not married and I don't have children, and my cervical erosion is not serious!" After asking, the doctor learned that Xiaolan started having sex at the age of 20 and has had 3 boyfriends so far. Her test report showed: "TCT: LSIL (CIN1), HSIL is not excluded; HPV high-risk gene type 16 (+)". Experts say that having multiple sexual partners greatly increases the chances of infection and persistence of the virus. HPV16 infection should be the main cause of her illness.

Experts say that HPV is human papillomavirus, and cervical cancer is caused by HPV infection. About 20% of sexually active women will be infected with HPV. Generally, there will be no discomfort after infection, and most infections will naturally subside within six months to a year, but a small number of persistent viruses can cause cervical lesions and even cancer. "Cervical cancer is one of the few tumors with a clear cause. More than 90% of cervical cancers are accompanied by HPV infection. It can be said that HPV infection is the culprit of cervical cancer."
