Dr. Oz says that 85 percent of all breast cancer happens in those ducts. "But if you look inside the duct when the cancer is first beginning to start, it stays there for a while. It doesn't break through these walls like that. It takes a while to do that. If you can find the cancer when it's early, you can take it out and it's done."
What you don't want, Dr. Oz says, is for cancer to spread to the lymph nodes and beyond. "The key is to get that cancer before it penetrates through the wall. If you find it then, it's a done deal," he says. "You have a baseline defense systeman immune system. You want to help it, but it can only defend you for so long."
