Approximately 85 to 87 percent of all cases are caused by tobacco use, making lung cancer one of the most preventable cancers. Another several percent stems from radon exposure. Individuals who have been smokers and asbestos workers have a much higher risk of dying of lung cancer.
In the last decade, researchers have identified many of the genes involved in the development of lung cancer. They have found that turning off the activity of certain cancer-blocking genes called tumor suppressor genes such as p53 and Rb, and turning on various cancer-promoting genes such as c-myc, ras and bcl-2 may play roles in triggering lung cancer. More recently, scientists have identified a gene associated with a cluster of inherited lung cancer. The challenge remains for researchers to turn this knowledge into advances in diagnosis, therapy or prevention.You may have asbestos-containing substances in your home or office, especially those built before 1978. If the material is in good condition, LEAVE IT ALONE! To be certain, however, you may want to have the materials inspected, and, if necessary, repaired or removed.
Repair usually involves either sealing or covering asbestos material. Sealing (or encapsulation) involves coating materials so that asbestos is sealed in. This process is only effective for undamaged asbestos-containing substances.

If materials are soft or crumbly or otherwise damaged, sealing is not appropriate. Covering involves placing something over or around the material that contains asbestos to prevent release of fibers.
Asbestos removal is an expensive and hazardous process and should be a last resort. Situations where removal may be required include remodeling, major structural changes, and if the asbestos material is damaged and can not be otherwise repaired.
Any action to minimize dust generation from naturally occurring asbestos sources will generally help reduce exposure. If you are unsure whether the rock on your property is ultramafic a registered geologist can be contacted to evaluate it.
Removal is complex, and should be done only by a contractor with special training. Improper removal may increase the health risks to those exposed!
If you think that you may have been exposed to any amount of loose asbestos in any degree, no matter how long ago, see your doctor. Don't smoke! It increases your chances of being affected by asbestos.
