What is the most common histological type of cervical cancer?
Squamous cell carcinoma (SCC) is the predominant histological type accounting for three-fourths of all cervical cancers. Adenocarcinoma and adenosquamous cell carcinoma represent 10–15%, and other or unspecified histology represent the remaining 10–15% [2,3].
WHO histological classification of cervical cancer?
The histologic classification of epithelial tumors of the uterine cervix by the World Health Organization (WHO) separates them into three main groups: squamous cell carcinomas, adenocarcinomas, and other epithelial tumors (Table 115-1).
What is histology of cancer?

What are cervical cancer cells called?
Most (up to 9 out of 10) cervical cancers are squamous cell carcinomas. These cancers develop from cells in the exocervix. Squamous cell carcinomas most often begin in the transformation zone (where the exocervix joins the endocervix). Most of the other cervical cancers are adenocarcinomas.
What is an epithelial tumor?

What is histology and why is it important?
Histology is the study of how tissues are structured and how they work. Knowing what a normal tissue looks like and how it normally works is important for recognizing different diseases. It also helps in figuring out what causes certain diseases, how to treat those diseases, and whether the treatment has worked.
What are survival rates for cervical cancer?
— For cervical cancer that has spread nearby in the body, five-year survival is 57 percent (SEER). — For cervical cancer spread to distant areas of the body, five-year survival is 17 percent (SEER). — Cervical cancer rates are rising for women in rural/nonmetropolitan areas (CDC).
What is the success rate of cervical cancer?
When detected at an early stage, the 5-year survival rate for women with invasive cervical cancer is 92%. About 44% of women with cervical cancer are diagnosed at an early stage. If cervical cancer has spread to surrounding tissues or organs and/or the regional lymph nodes, the 5-year survival rate is 56%.
What causes cervical cancer?
Cervical Cancer Causes. Cervical cancer is caused by abnormal cells of the cervix that gradually develop into pre-cancerous and cancerous cells. Most of the time, cervical cancer is caused by a virus called human papillomavirus, or HPV.
