Most of the lung tumors are malignant that is cancerous. They can invade and destroy the healthy tissues around them and can spread throughout the body. The lung is a bad place for a cancer to begin because it contains a rich network of both blood vessels and lymphatic channels through which cancer cells can grow. When lung tissues break down, the intake of oxygen and removal of carbon dioxide is not proper which leads to a condition known as emphysema. Smoker lungs convert to cancer lungs very easily therefore consumption of tobacco should be restricted for healthy lungs.

Smoking causes multiple lung diseases. Cigarette smoking causes most cases of lung cancer. Tobacco smoke can trigger an attack or make an attack worse in a person with asthma. Smokers are 12 to 13 times more likely to die from COPD than nonsmokers. Tobacco smoke contains more than fifty chemicals which cause cancer. Nicotine, an important constituent of tobacco, is a highly addictive psychoactive drug. Nicotine causes physical and psychological dependency which leads to addiction. Tobacco is consumed through cigarette, cigar, hookah, tobacco chewing, etc. It can cause several cardiovascular, respiratory or kidney diseases. It also affects pregnant women and newborn babies.

X-rays of your chest can be done at imaging centers, hospitals, and even in some doctors' clinics. If the x-ray result is normal, you probably may not have lung cancer but some lung cancers may not show up on an x-ray. If something suspected is seen in the X ray, your doctor may order more tests for confirming the prelim diagnosis.
