What are the 2 primary types of cervical cancer?

• A. Squamous cell carcinoma and adenocarcinoma
• B. Adenocarcinoma and sarcoma
• C. Small cell carcinoma and squamous cell carcinoma
• D. Basal cell carcinoma and melanoma

Answer: (A)

Two primary histologic types of cervical cancer are squamous cell carcinoma and adenocarcinoma. Squamous cell carcinoma arises from the squamous epithelium that lines the outer cervix and the transformation zone where squamous and glandular cells meet; it is by far the most common form. Adenocarcinoma comes from the endocervical glandular cells within the canal and is the second most frequent type. Both types are closely linked to HPV infection and together account for the majority of cervical cancers. Other options listed are not the main cervical cancer types: sarcoma is a rare mesenchymal tumor in this area, small cell carcinoma is uncommon and not one of the primary forms, and basal cell carcinoma or melanoma are not typical cervical cancers.
