Cervical hypertrophy is not necessarily a precursor of cancer. Cervical hypertrophy may be a precursor of cancer, or it may be caused by other reasons, which need to be analyzed specifically before a clear diagnosis can be made. 1. Cervical cancer: cervical cancer may cause cervical hypertrophy, however, it may not cause cervical hypertrophy, especially in early stage of cervical cancer, which usually does not cause cervical hypertrophy, until the cancer foci are relatively large, then it will cause thickening of cervical canal. 2. Other reasons: besides cervical cancer, there are many other factors that can cause cervical hypertrophy, such as columnar epithelium squamous epithelium hyperplasia caused by natriuretic cysts, which causes cervical hypertrophy; inflammatory factors can also lead to cervical hypertrophy due to hyperplasia, which are relatively common symptoms and generally do not affect the health. It is recommended that women undergo cervical cancer screening once a year, and once diagnosed, they need to undergo active treatment.
