Malignancy treated with curative intent and with no known active disease present for ≥3 years prior to registration and felt to be at low risk for recurrence by the treating physician 2. Adequately treated non-melanomatous skin cancer or lentigo maligna without evidence of disease 3. Adequately treated cervical carcinoma in situ without evidence of disease There is no exclusion of patients based on sex, ethnicity or race.
