Histopathology And Natural Course Of Cervical Cancer

85% of cervial cancer are "squamous cell carcinomas", as the pathologist classifies them. For comparison here is a normal histology finding of the cervix. This is the area of the cervix that is visible to the physician's eye when he does a speculum examination and normally this is covered with cells called "squamous cells". At times the lining of the cervical canal, which has adenoid glands, grows a bit out of the canal onto the outside surface of the cervix.

As the name says, they are a mixture of both malignant adenocarcinoma and malignant squamous cell carcinoma. These cancers are what the pathologist calls "poorly differentiated carcinoma", meaning that they are fast growing tumors with a cancer survival rate that is very poor. To complicate the picture, there are three grading types of squamous cell carcinoma: a well-differentiated, a moderately differentiated and a poorly differentiated one . Each of them has a different grade of malignancy with the most mature cell type having the best longterm survival and the most immature (poorly differentiated) type having the worst survival.

Here is a link to an authoritative text on cervical cancer histology and the significance in the direction of treatment.
