Energy Balance Interventions in Increasing Physical Activity in Breast Cancer Gene Positive Patients, Lynch Syndrome-Positive Patients, CLL Survivors or High-Risk Family Members

This pilot clinical trial studies different types of energy balance interventions to see how well they work in increasing the physical activity levels of breast cancer gene-positive patients, Lynch syndrome-positive patients, chronic lymphocytic leukemia (CLL) survivors or family members of cancer survivors who are at high risk for cancer. Increasing exercise and eating healthy foods may help reduce the risk of cancer. Studying how well different types of interventions work in motivating cancer survivors or high-risk family members to increase exercise and healthy food choices may help doctors plan the most effective motivational program for cancer prevention.
