Lung Cancer: Symptoms, Risks and Prevention

Lung cancer originally starts with growth of cancerous cells in the lungs. It can spread to other parts of the body. More women are dying of lung cancer these days than breast cancer.

Lung cancer is less common and is usually associated with tobacco abuse. Non-small lung cancer is more common and it may or may not occur because of tobacco use.

Signs and Symptoms

A cough that is more than 3 weeks old and not getting treated with medicines is an early symptom of lung cancer. Blood in sputum, loss of appetite, unexplained weight loss, shortness of breath and regular chest pain are some of the major signs and symptoms.

Risk Factors

Smoking is number one cause of development of lung cancer. Low-tar tobacco cigars and cigarettes are of no help. Passive smoking is equally harmful.

People working for long hours in areas which have high amounts of heavy and toxic metals in the air are at a much greater risk of developing lung cancer. Laborers in charcoal factories or coal mines must take necessary precautions to prevention lung cancer.

Lung cancer may be result of an inherited gene.

Prevention

Since 50% of smokers end up getting lung cancer, quitting is the only way of prevention.

Laborers working in fields, mines and factories must wear masks to prevent inhalation of toxic carcinogens. They should not expose themselves to the toxic environment for more than the maximum limit allowed. Exposure to radon and asbestos is another cause of lung cancer, but it is rare. Asbestos is part of the insulation in many homes during construction. Regular renovations keep a check on the asbestos levels and keep them sealed. As long as it is not available for inhalation, it is safe.

Radon is found in soil of certain areas. Once it precedes its safety limits it becomes highly toxic and cancerous. Get the soil checked. Antioxidants will help your body to fight against cancerous cells. A diet rich in fruits and green vegetables will boost your immunity considerably. Regular exercise routine provides similar benefits.

Interestingly, women have a higher survival rate than men who are suffering from lung cancer. Woman respond better to the treatment.
