Cervical nuchal translucency is not a precursor of cervical cancer. Cervical cyst is a manifestation of chronic cervicitis, however, cervical cancer is a malignant tumor, and cervical cyst is not an early clinical symptom of cervical cancer, so the development of cervical cancer is not necessarily related to cervical cyst. Cervical nuchal translucency is a disease caused by chronic inflammation of the cervix. It usually has no obvious symptoms and is usually detected during gynecological examination. It usually does not require medication, but only requires the patient to pay attention to personal hygiene in daily life, such as cleaning the perineum with warm water regularly and changing underwear regularly to avoid further aggravation of the inflammation. If patients have obvious symptoms of infection, they need to seek medical treatment in time. Cervical cancer is mainly a disease caused by HPV infection, premature sexual activity and multiple sexual partners. There are no obvious symptoms in the early stage. As the disease progresses, patients may experience contact bleeding, such as vaginal bleeding after sexual intercourse or gynecological examination. Patients discharge white, bloody, thin water-like fishy-smelling or foul-smelling leucorrhea, and in advanced stage, patients have large amount of rice-soup-like or pus-like foul-smelling leucorrhea. Most of the cervical cancers need surgery and combined with chemotherapy and radiotherapy for comprehensive treatment after surgery.
