In order to deal properly with lung cancer we need to understand and — if possible — remove the underlying causes and risk factors. We need to ask: "What else is going on inside the body that might allow lung cancer to develop?"
Accurate diagnosis of the factors behind lung cancer consists of three steps:
|Cigarette Smoke Damage||53%||Possible|
Have you suffered from Lung Cancer?
Possible responses:→ No / don't know
→ Yes but now resolved for over 5 years
→ Yes but now resolved for under 5 years
→ Current problem but containable
→ Current problem and aggressive/spreading
Lung cancer is the leading cause of cancer death among both men and women. Some 90% of lung cancer in men and 79% of lung cancer in women is directly attributed to smoking. In fact, smoking increases the chance of developing lung cancer 22-fold for males and 12-fold for females. The relative risk of developing lung cancer is directly proportional to the amount and duration of smoking. The 250% increase in the occurrence of lung cancer between 1960 and 2000 followed the rise in cigarette smoking 20 years earlier.
Smoking causes lung cancer of all the principal histologic types: squamous cell, large cell, small cell and adenocarcinoma. Small cell cancer is the most aggressive type of lung cancer and has the worst prognosis. This kind of cancer tends to grow rapidly spread to other parts of the body early. Large cell cancer spreads to lymph nodes of the chest and it enters the blood stream where it gets carried to other organs such as the liver, bone, brain, and spinal cord. Among men there is an increased proportion of squamous cell carcinoma, while in women there is an increased proportion of adenocarcinoma.
