The pathological types of cervical cancer are divided into three main types, the first is squamous carcinoma, which is more common, the second is adenocarcinoma, and the third is adenosquamous carcinoma. Squamous carcinoma is more common and is generally differentiated into three levels: first level is highly differentiated, second level is moderately differentiated, and third level is poorly differentiated; the lower the differentiation, the higher the malignancy and the prognosis is relatively poor. There are two types of adenocarcinoma, one is mucinous adenocarcinoma, which is relatively common and is divided into high, medium and low differentiation. The second type of adenocarcinoma is malignant adenoma, which is often accompanied by lymph node metastasis. Adenosquamous carcinoma generally accounts for a very small percentage of cervical cancer, 3%-5%, and generally contains both adenocarcinoma and squamous carcinoma components. On the whole, there are three types of cervical cancer: squamous, adenocarcinoma and adenosquamous carcinoma, among which squamous carcinoma is the most common one.
