Surgery For Lung Cancer

Everyone knows that smoking is a risk factor for lung cancer. It’s not just cigarettes; regardless of what a person smokes and what they use to smoke it, the act of drawing smoke into the lungs is a lung cancer risk. The risk is inherent to smoking, not something in the cigarettes, and particularly not something in commercial cigarettes, or cigarettes from major producers. Other risk factors include any exposure to sort of air pollution or particulate matter, radon gas found particularly in older buildings, and a family history of the disease.

Because, as with most cancers, treatment is effective in early stages but far less effective later on, early detection is important. People with lung cancer tend to have respiratory symptoms such as a new chronic cough—someone who is a smoker will tend to have a chronic cough anyway, but a change can be a bad sign—shortness of breath, wheezing, and hoarseness. Coughing up blood is often a sign of lung cancer, and in any case it is clearly a sign of something.

Early stage lung cancer is normally treated surgically. In the later stages, however, there is usually too much cancerous tissue for it to be safely removed. When treatment is still possible at this stage, it will be chemotherapy or radiation therapy, on their own or together with surgery. In one study, surgery had better outcomes than radiation treatment in patients with certain types of cancer. Counter-intuitively, another study found that removal of an entire lobe of the lung is more effective over the long term than simply removing the tumor—even though lung cancer is one of the deadliest cancers. The more drastic surgery removes portions of the lung that are not cancerous but are likely to become cancerous, parts that removing only the tumor leaves intact.

Lung transplants are also possible, but as with other transplant procedures, the use of this approach is hampered by a need to ensure the transplanted organ is not rejected, and a perpetual shortage of donors. Scientists now think the shortage of long donors can be alleviated slightly by including transplants from donors who drowned or asphyxiated—that is, where death was due to an acute injury, but who did not have chronic lung problems.
