Caught it on Slashdot. From the original post at BBC:

Scientists around the globe are now working to catalogue all the genes that go wrong in many types of human cancer. The UK is looking at breast cancer, Japan at liver and India at mouth. China is studying stomach cancer, and the US is looking at cancers of the brain, ovary and pancreas.

…scientists from the 10 countries involved say it will take them at least five years and many hundreds of thousands of dollars to complete this mammoth task.

and

The lung cancer DNA code had more than 23,000 errors largely triggered by cigarette smoke exposure. From this, the experts estimate a typical smoker acquires one new mutation for every 15 cigarettes they smoke. Although many of these mutations will be harmless, some will trigger cancer.
