Factors Affecting Non-Histologically Proven Invasive Cancer of the Uterine Cervix that Had an Abnormal Pap Smear: Results of the CCS Program.

Background: Cervical cancer (CC) ranks fourth among cancers diagnosed around the world, but early detection and treatment can reduce invasive cervical cancer and mortality. Screening programs (CCSP), such as the one covering Thailand's 75 provinces, use histology to confirm cases. The study determined the incidence rate (IR) and investigated the factors associated with non-histologically proven invasive cancer of the uterine cervix (non-HPICUC) with an abnormal pap smear from the CCSP at Mahasarakham Hospital, Thailand.
