Cervical dysplasia: early intervention.

Cervical cancer is the second-most common cancer in young women and is one of the most common causes of cancer deaths among women, particularly in minorities and in impoverished countries. Cervical dysplasia, a premalignant lesion that can progress to cervical cancer, is caused primarily by a sexually transmitted infection with an oncogenic strain of the human papillomavirus (HPV). Not all women with the virus develop cervical dysplasia or cervical cancer. It has been postulated there are multiple host factors that contribute to progression of disease. Many of these factors, such as nutrient deficiencies, can be reversed, which will result in regression of dysplastic lesions. Studies have shown dietary intervention and nutrient supplementation to be effective in preventing cervical cancer. Additionally, local escharotic treatment combined with systemic treatment shows significant potential in reducing dysplasia. Recent advances in vaccination technology demonstrate the effectiveness of an HPV vaccine. The vaccine, however, may have many social and cost-prohibiting limitations, as well as health side effects.
