Women who develop cancer in one breast face a very difficult decision.

You can never be assured of removing all breast tissue. But it is a huge reduction in breast cancer.

We have a growing number of breast-cancer survivors who face a very difficult decision about whether or not to use HRT,

The sight of cancer-ridden lungs and yellowing teeth may reinforce a non-smoker's decision not to light up, but does nothing to convince those already addicted. The reason for this is a mixture of denial and familiarity.

While it is the more the more unusual scenario that someone who never smoked would develop lung cancer, 10 to 15 percent of the cases do occur in non-smokers. One of the major problems is, by the time it's detected, it's often quite far advanced.

But now we have firm data showing we should use (it) in most women with advanced ovarian cancer who have had successful surgery to remove the bulk of their tumor.
