At what age does cervical cancer occur most often?

Cervical cancer mostly occurs in women aged 35-55, with the peak age group being 40-49 years old. Cervical cancer is related to factors such as human papillomavirus infection, low immune function, and long-term smoking.

The incidence of cervical cancer in women under 35 years old is relatively low, but it has become younger in recent years. The incidence rate among women aged 30-34 years begins to increase significantly, which may be related to factors such as premature sexual life, multiple sexual partners, and HPV infection. The incidence rate is significantly higher in women aged 35-44 years. At this stage, women's immune function gradually declines, and their ability to clear the HPV virus is weakened. At the same time, along with changes in hormone levels, cervical epithelium is more likely to develop precancerous lesions. The incidence rate reaches a peak in women aged 45-55, which is related to persistent HPV infection and long-term chronic inflammation of cervical tissue. The incidence rate gradually decreases after the age of 55, but postmenopausal women still need to be screened regularly, because some cervical cancers develop slowly and may not be discovered until this age.

Regular cervical cancer screening is an important means to prevent cervical cancer. It is recommended that women over 21 years old or with a history of sexual intercourse undergo cervical cytology examination every 3 years. Women over 30 years old can be combined with HPV testing. Maintaining a single sexual partner, getting the HPV vaccine, and avoiding smoking can help reduce the risk of the disease. If symptoms such as abnormal vaginal bleeding or contact bleeding occur, you should seek medical examination promptly.
