Easy Tool for Screening of Cervical Precancerous and Cancerous Lesions

Cervical cancer is an important global public health problem and approximately 80% of the cases are diagnosed in developing countries. Human papilloma virus (HPV ) causes cervical cancer which is the forth most common cancer in women worldwide. According to WHO, there are approximately 500,000 new cases and 250,000 deaths from cervical cancer every year worldwide. Cervical cancer is caused by the sexually transmitted HPV, which is the most common viral infection of the reproductive tract. Almost all sexually active individuals will be infected with HPV at some point in their lives and some may be repeatedly infected. The peak time for infection is shortly after becoming sexual active. The majority of HPV infections resolve spontaneously and do not cause symptoms or disease. However, persistent infection with specific types of HPV (most frequently, types 16 and 18) may lead to precancerous lesions. If untreated, these lesions may progress to cervical cancer. So, screening is very much necessary for early detection of precancerous and cancerous lesions by an easy and effective tool to give treatment.
