Worldwide, the 5 most common types of cancer that kill men are (in order of frequency): lung, stomach, liver, colorectal and oesophagus
Worldwide, the 5 most common types of cancer that kill women are (in the order of frequency): breast, lung, stomach, colorectal and cervical
Tobacco use is the single largest preventable cause of cancer in the world.
40% of cancer could be prevented, mainly by not using tobacco, having a healthy diet, being physically active and preventing infections that may cause cancer.
Arsenic, Nickel, Asbestos, Painting materials, nonarsenic pesticides, diesel exhaust, chromates, man-made mineral fibers, etc., cause lung cancer.
Left lung is smaller than the right lung.
The average pair of human lungs can hold about 6 liters of air, but only a small amount of this capacity is used during normal breathing.
Lung diseases are caused by virus, bacteria and fungus.
Environmental pollution is main cause of asthma.
In sensitive individuals, asthma symptoms can be triggered by breathing in allergy-causing substances (called allergens or triggers). Triggers include pet dander, dust mites, cockroach allergens, molds, or pollens. Asthma symptoms can also be triggered by respiratory infections, exercise, cold air, tobacco smoke and other pollutants, stress, food, or drug allergies. Aspirin and other non-steroidal anti-inflammatory medications (NSAIDS) provoke asthma in some patients.
Chronic obstructive pulmonary disease is partially reversible airflow obstruction caused by an abnormal inflammatory response to toxins, often cigarette smoke. α1-Antitrypsin deficiency and a variety of occupational exposures are less common causes in nonsmokers. Symptoms are productive cough and dyspnea that develop over years; common signs include decreased breath sounds and wheezing. Severe cases may be complicated by weight loss, pneumothorax, right heart failure, and respiratory failure. Diagnosis is based on history, physical examination, chest x-ray, and pulmonary function tests. Treatment is with bronchodilators, corticosteroids, and, when necessary, O2. About 50% of patients die within 10 yr of initial diagnosis.

Answer 3

if someone has pneumonia it is important to keep active since the fluid is in the lungs it needs to be moved around in order to be coughed up. Laying in bed will only worsen the condition.
