What Causes Cancer?
Scientists and researchers do not really know what causes cancer, but there is some understanding of why people get cancer. People get cancer based on their genetics and certain environmental or behavioral triggers. For example, if a close relative had lung or skin cancer, you may be more likely to inherit the tendency to get lung or skin cancer. If you are exposed to environmental or behavioral triggers such as smoking cigarettes or excessive sun exposure, you may be more likely to get lung or skin cancer. The combination of genetics and environmental and behavioral triggers determine the likelihood that you will get cancer.
