Trends in Cervical Cancer:

Cervical lesions are among the most common diseases in women, and in their most severe form, develop into cervical cancer. Cervical cancer is one of the most common malignant tumors in gynecology, ranking first in incidence among female malignancies in China. Globally, approximately 500,000 new cervical cancer cases are reported each year, with 80% occurring in developing countries. China accounts for about 185,000 new cases annually — one-third of the global total. In recent years, the onset of cervical cancer has trended younger, with incidence among young women growing at a rate of 2–3% per year.

Risk Factors for Cervical Cancer and Precancerous Lesions Include:

Early marriage, early childbearing, and multiple pregnancies;

Multiple sexual partners or unhygienic sexual behavior by either spouse;

Viral infection: primarily infection with oncogenic human papillomavirus (HPV);

Compromised immune function: such as in HIV-positive individuals;

Family history of cervical cancer, endometrial cancer, or similar conditions;

Smoking and drug use;

Nutritional factors: deficiency in carotenoids, Vitamin A, Vitamin C, and folic acid.

Symptoms of Cervical Precancerous Lesions:

Increased vaginal discharge; contact bleeding — light bleeding after sexual intercourse or bimanual pelvic examination, known as contact bleeding.

Cervical Cancer Is Preventable and Treatable:

Early-stage cervical cancer often presents with no symptoms or very mild symptoms that are easy to overlook. Because cancer cells metabolize faster, proliferate more actively, and have adhesion strength about 10 times lower than normal cells, even small early-stage lesions can shed large numbers of cancer cells from the surface. Through exfoliative cytology, cervical cancer can be detected and diagnosed early.

Note: Cervical cancer is the only cancer with a known cause that the World Health Organization (WHO) recommends for large-scale screening. It is preventable and treatable when caught early, and early intervention produces highly effective results.

Common Clinical Screening Methods for Cervical Cancer:

1、Liquid-Based Cytology (LBC)

A new cytological technology using liquid-based thin-layer cell preparation. Cervical cells are tested and reported according to the TBS system. Compared with conventional Pap smears, LBC significantly improves specimen adequacy and the detection rate of abnormal cervical cells.

2、Virology Testing — HPV-DNA Detection

Extensive research confirms that persistent high-risk human papillomavirus (HPV) infection is the primary cause of cervical cancer.

3、DNA Quantitative Analysis

Cellular DNA quantitative analysis is a method combining qualitative and quantitative diagnosis. It uses DNA ploidy analysis technology for exfoliative cytology, performing qualitative cell diagnosis on the basis of liquid-based thin-layer cytology preparation. It has become a routine clinical detection method in North America and Europe, showing significantly higher sensitivity than conventional manual slide reading, and enables detection of more early-stage cervical cancer patients, allowing them to receive further clinical confirmation and treatment in a timely manner.

4、Colposcopy

An important supplementary method for early diagnosis of cervical cancer and precancerous lesions. Colposcopy can detect subclinical lesions invisible to the naked eye, and enables targeted biopsy of suspicious lesion sites, thereby improving biopsy positivity rates and diagnostic accuracy.
