In addition to hyperplasia, microscopic examination of a biopsy specimen can detect another type of noncancerous condition called "dysplasia." Dysplasia is an abnormal type of excessive cell proliferation characterized by loss of normal tissue arrangement and cell structure. Often such cells revert back to normal behavior, but occasionally they gradually become malignant. Because of their potential for becoming malignant, areas of dysplasia should be closely monitored by a health professional. Sometimes they need treatment.N.B: Treatment for dysplasia depends on the severity and location of the dysplasia as well as other health factors-such as smoking, which increases risk for all types of cancer-or a condition such as INFECTION with HUMAN PAPILLOMAVIRUS (HPV), which increases risk for cervical cancer. Mild dysplasia may revert to normal growth; often the doctor will recommend diligent observation with examination every three to six months to monitor cell activity at the site. Electrocautery (burning), cryotherapy (freezing), laser ablation, and surgical excision are among methods for eradicating dysplasia. Dysplasia may recur, depending on its cause, though in most circumstances does not return after treatment.
