In an interview with CBS
, Dr. Jon LaPook explained the results of the CDC study.
"We know a third of cancers are caused by smoking," said LaPook. "And up to a third are caused by obesity and lack of exercise. So as many as two-thirds of cancers are potentially preventable...Belly fat seems to increase the number of inflammatory compounds, increase the levels of hormones like estrogen and insulin. That can cause changes inside of cells that then lead to cancer."
“Americans don’t understand the association between cancer and obesity,” adds Dr. Marcus Plescia
, director of the division of cancer prevention for the CDC. “They know about the links [from obesity] to diabetes, heart disease and arthritis, but many don’t know about this.”
Another thing that many Americans may not know: very small lifestyle changes could prevent cancer. For example, this news from the CDC comes hot on heels of a report about breast cancer. According to ABC News
, even the consumption of one alcoholic drink a day could contribute to the development of breast cancer.
