Screening for cervical cancer: what is a cervical smear test and why is it so important to have one regularly?

Article Abstract:

Cervical cancer is a common cancer affecting women, with abnormal changes in cervical cells occurring up to 15 years before a cancer develops. The cause is not known but it is related to sexual activity and there may be some involvement of sexually transmitted infections, as well smoking and the use of oral contraceptives. The early stages show no symptoms and the cancer can become invasive if left untreated. A smear test can identify pre or early cancerous lesions and treatment at this stage can prevent progression to invasive cancer. The technique for obtaining a cervical smear is given.

Antibody reactivity to HPV E6 and E7 oncoproteins and early diagnosis of invasive cervical cancer

Article Abstract:

A blood test based on the E6 and E7 proteins from human papillomavirus is not very accurate in identifying women infected with the virus who may develop cervical cancer. Even studies of women who already have cervical cancer found that not all had antibodies to these viral proteins. Some types of human papillomavirus have been linked to cervical cancer, especially types 16 and 18.
