Lung cancer is a serious health problem affecting both men and women. It is the largest cause of cancer related deaths in men and is the second cause of cancer related deaths in women. What many people might not know is that lung cancer is the result of several different things and not just from smoking tobacco alone. Whatever the causes of lung cancer, it is important for us to know what the common lung cancer symptoms are so that we you take early remedial or corrective actions to contain or cure this deadly disease. Early effective medical intervention increases the percentage of an early cure from the disease.
Lung cancer is a disease caused by uncontrolled cell growth in the lungs. Smoking is the number one cause of lung cancer, accounting for about 87% of all lung cancer cases diagnosed. Cigarette smoke contains over 60 carcinogens which included the harmful and addictive nicotine. Prolonged exposure to the cigarette smoke (whether as an active or a passive smoker) can lower your body's immune systems to fight the malignant cancer growth tissue. In addition to smoking, there are other causes of this disease like radon gas from the earths crust, asbestos and various viruses like the human papillomavirus, JC virus, simian virus 40 (SV40), BK virus and cytomegalovirus.
The specific noticeable lung cancer symptoms include the dyspnea or shortness of breath, hemoptysis or coughing up blood, chronic coughing, wheezing, chest or abdominal pain, weight loss, fatigue, and difficulty in swallowing. Cancer cells may grow in our airway, obstructive airflow and cause dangerous breathing difficulties. This can result in the cancer patient getting pneumonia which in turn causes muscle weaknesses and other symptoms. Surprisingly, lung cancer is often diagnosed after the patients going in thinking they have pneumonia.
There are also many non-specific symptoms of lung cancer as well. These symptoms include bone pain, fever and weight loss. Lung cancer often spread to other parts of the body as well, including the bone, spinal cord, liver and the brain. This act of the cancer spreading is known as metastasis.
Being one of the most common forms of cancer, it is incredibly important for us to be informed of the many lung cancer symptoms. It is also important for us to know what causes lung cancer so that we can take necessary precaution to reduce our chances of getting it. Obviously smoking is a horrible decision, not only for the cancer related reasons but also for our general health and well-being as well. But also knowing the other causes like radon gas, asbestos and the other various viruses is just as important as well. If you feel you have been exposed to any of these causes and have the lung cancer symptoms listed above, it is important that you consult your doctor early so that necessary diagnostic tests can be carried out to ascertaining your health condition.
