The Outlook is not good

I just looked up lung cancer on the NHS Direct website as I know next to nothing about it. This was in the diagnosis section:

"The outlook for people with lung cancer is not good. Only 20% of people are alive one year after being diagnosed with the disease, and only 8% survive for five years... Although lung cancer is only one of several serious diseases caused by cigarette smoking, it is often the most distressing because it is almost completely preventable."

It sounds horrible.
