Obesity, sedentary lifestyle and/or exposure to chemicals like BPA in microwave plastics may increase your child’s risk for cancer. 50% of all cancers are preventable but it may take a change in your current lifestyle. If you do not encourage your kids to eat right or exercise, you are putting them at greater risk for cancer. Most parents tend to put sunscreen on their kids and not smoke around them. However most do not demand a form of exercise or reduce chemical exposure because they do not realize that they are equally important.
