cigarette smokers

If lung cancer and heart disease aren't enough, cigarette smokers are also at higher risk for developing, among other things, pancreatic cancer.

Now, researchers have preliminary evidence indicating one possible reason why. The scientists show that nicotine in cigarettes increases the production of a protein that promotes cancer cell survival, invasion and spread.

Cigarette smokers who were treated for cerebral aneurysms with coil embolization (blocking of a blood vessel) are at greater risk of developing another aneurysm, say neurological surgeons.
