Routine diagnosis of cervical precancerous lesions

What is the basis for diagnosing cervical precancerous lesions? This is what everyone is more concerned about. Only by grasping the basis for diagnosing cervical precancerous lesions can we help everyone make an active diagnosis. So what is the basis for diagnosing cervical precancerous lesions? The following is a professional explanation given by experts.

Diagnosis of cervical precancerous lesions is based on:

1. The macroscopic examination originates from the cervical canal and infiltrates the cervical canal wall. When the cancer lesion grows to a certain extent, it will protrude to the external cervical os and often invade the paracervical tissue. The cancer lesion can be papillary, bud-like, ulcerated or infiltrative. If the lesion grows inward, the appearance of the cervix may be completely normal, but the cervix in the cervical canal will swell like a barrel.

2. Microscopic examination

⑴ Mucinous adenocarcinoma: The most common type, originating from the cervical columnar mucinous cells, with glandular structure visible under the microscope and cells containing mucus.

⑵ Cervical malignant adenoma: also known as minimally invasive adenocarcinoma. The tumor cells appear benign and often infiltrate the deep layers of the cervical wall.

⑶ Squamous adenocarcinoma: It originates from the subcolumnar cells of the cervical mucosa. It is rare and the cancer cells are immature. It develops towards both adenocarcinoma and squamous cell carcinoma, hence the name.
