Cervical cancer IB2 is a stage, which is mainly caused by HPV infection and also related to factors such as low immune function and smoking. Usually, cervical cancer is divided into stages I~IV according to different stages of development, among which stage I can be divided into stage IA and stage IB, while stage IB2 generally refers to invasive carcinoma with a maximum diameter greater than or equal to 2cm and less than 4cm. The etiology of each stage is the same, mainly due to HPV infection, but most of the population can be cleared of HPV infection by body immunity, and only a few patients will have persistent high-risk HPV infection, which will lead to cervical precancerous lesions and develop into cervical cancer. At the same time, immunocompromised patients and people with multiple sexual partners and early sexual intercourse also increase the risk of HPV infection. If patients still have bad habits such as smoking after HPV infection occurs, it will increase the risk of cervical cancer. The risk of cervical cancer is also relatively high in the case of multiple pregnancies and births and long-term infection. It is recommended that patients with cervical cancer IB2 should clarify the extent of the disease according to their own staging in time and take reasonable treatment under the guidance of doctors.
