Your lungs can be very badly affected by smoking. Coughs, colds, and asthma are just a few of the effects. Smoking can cause life-threatening diseases such as pneumonia, emphysema and lung cancer. Smoking causes about 85% of deaths from lung cancer and 83% of deaths from chronic obstructive pulmonary disease (COPD).
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.
Chronic bronchitis or pneumonia that doesn't go away after treatment or that keeps coming back may be a sign of lung cancer. If you have symptoms of bronchitis or pneumonia, such as a cough, shortness of breath, mild fever and chills and discomfort in chest, you should contact your doctor as early as possible.
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.
Chest pain is the most commonly observed sign of lung cancer, but there are plenty of other signs you should know about even if you've never smoked. Whether you smoke regularly or have never smoked in your life, you should carefully look for these symptoms of lung cancer.
