A human papillomavirus infection meaning percentage of women diagnosed with cervical dysplasia will go on to develop cervical cancer, which is one of the most preventable cancers.
In this protocol you will learn about factors that increase risk of cervical dysplasia and how cervical dysplasia is classified. The benefits and risks of currently available treatments will also be reviewed, and evidence concerning integrative interventions such as B vitamins and diindolylmethane DIMwhich have been studied in the context of cervical dysplasia, will be presented.
Women who opt for watchful waiting after a diagnosis of low-grade cervical dysplasia should adopt the healthy lifestyle choices and risk reduction measures presented in this protocol. If the condition persists or worsens, active treatment can be instituted.

Green Tea Extract: Women with cervical dysplasia who supplemented with green tea extract had nearly a 7 times higher response rate than women receiving no treatment.

Cervical cancer usually develops over a period of several years ACOG During this time, the cells on or around the cervix become abnormal. The cellular abnormalities that occur before cancer is present are usually called cervical intraepithelial neoplasia CIN.
Cervical dysplasia and cervical cancer are classified along a spectrum of increasing cervical cell abnormality. The goal human papillomavirus infection meaning classification is to determine the degree to which the cervical cells have become abnormal, and whether human papillomavirus infection meaning is needed, since lower degrees of dysplasia may resolve on their own without treatment. Risk factors interact and may be additive, so it is usually difficult to say that a given factor is responsible for any one case of cervical dysplasia or cancer La Vecchia ; Arnheim Dahlstrom ; ACS b.
