  1. Cancer Prevalence in U.S.: 14.5 Million (2017)

    2. Limit Alcohol to 1 drink per day for women and 2 drinks per day for men
  2. Maintain a healthy weight
    1. Obesity is related to Breast Cancer, Colon Cancer, Endometrial Cancer, Renal Cancer
  3. Exercise regularly

  1. Exposure to power lines does not increase cancer risk
    1. Finnish study of n=8415 cancer cases near power lines
    2. Compared with cancer Incidence over all of Finland
    3. No difference found

  2. Exposure to Cell Phones
    1. Does not appear related to Brain Tumor risk
    2. Long latency period however may require longer studies
    3. Retrospective study
      1. Brain Tumor patients (782) compared with 799 controls
      2. Inpatients from across U.S. surveyed 1994 to 1998
