Melissa Etheridge says it is the acidic western diet that harms the body and ultimately gave her cancer.
"Our own western lifestyle is one of the reasons that half of us have cancer - because our western lifestyle is so acidic; the food we eat causes acid... the meats, the processed foods... and it's really taxing us, and that's why we're seeing this epidemic," said the breast cancer survivor.
Now, Etheridge says she is healthier than ever.
"I'm healthier now than I've ever been because I'm understanding what breast cancer is... It's when your health is out of balance, when you're too acidic... It's not like a disease that finds you or something in your genes. It's actually your own cells going bad."
