INTRODUCTION: Lung cancer is a disease of uncontrolled cell growth in tissues of the lungs. It is one of the most common cancers in the United States, accounting for about 15 percent of all cases, or 170,000 new cases each year. It is also the worst cancer killer in America, taking more lives each year than breast, prostate and colorectal cancers combined, according to the American Cancer Society. It is the leading cause of cancer deaths in US women and is responsible for as many deaths as breast and all gynecological cancers combined.
SMOKING: Smoking, radon, and second hand smoking are the main causes. Smoking causes an estimated 160,000* deaths in the United States and leads to 85 percent to 90 percent of all lung cancers.
Smoking affects non-smokers by exposing them to second hand smoke. If a smoker stops smoking, the chance of lung cancer decreases steadily as damage to the lungs is repaired and contaminant particles are slowly removed.
RADON: An invisible and odorless gas generated by the breakdown of radioactive radium, which in turn is the product of decaying uranium, found in the earth’s crust.
Radon leads the way as the number one cause of lung cancer among non-smokers, according to EPA estimates. It causes between 15,000 and 22,000 deaths each year in the United States — 12 % of all lung cancer deaths are linked to radon.
RISK FACTORS: Include smoking cigarettes or cigars, in the present or in the past. Smoking does not account for all cases, but the role of passive smoking is increasingly being recognized as a risk factor, leading to policy interventions to diminish undesired exposure of non-smokers to others’ tobacco smoke.
A smoker who is also exposed to radon has a much higher risk. The more cigarettes you smoke per day and the earlier you started smoking, the greater your risk of lung cancer. High levels of pollution, radiation and asbestos exposure may also increase that risk.
SYMPTOMS: Include Chronic cough, Hoarseness, Coughing up blood, Weight loss & loss of appetite, Shortness of breath, Fever without a known reason, Wheezing, Repeated bouts of bronchitis or pneumonia and Chest pain.
Approximately 10% of people do not have symptoms at diagnosis; these cancers are incidentally found on regular chest x-rays. In fact, lung cancer can spread outside the lungs with no symptoms at all.
TREATMENT: Treatment depends on the cancer’s specific cell type, how far it has metastasize (spread), and the patient’s performance status. It also depends on the stage, or how far along it is.
Treatment options should be discussed with Your doctor. It may include chemotherapy, radiation and surgery. In the past few years, various molecular targeted therapies have been developed as treatments.
CONCLUSION: Lung cancer is the second most common form of cancer in most western countries, and it leads the way in cancer-related cause of death. It is the most common cause of cancer deaths in both men and women, accounting for nearly a third of cancer deaths yearly in the US.
It has become the subject of a great amount of research. Although the rate of men dying from it is declining in western countries, it is actually increasing for women due to the increased takeup of smoking by this group. We already know that the best way to prevent it is to quit (or never start) smoking. Three to five years after quitting, the risk of getting the disease is reduced by half.
