Lung cancer is a serious and life threatening disease, which starts in thelungs, two spongy organs located in the chest. The lungs are a part ofthe respiratory system in the humans and have the main role to inhale oxygenand exhale carbon dioxide in the breathing process. In many countries, it is a principal cause of death in men, as well as inwomen. The people who are smokers are at the highest risk to develop this devastatingdisease and therefore, smoking should be quitted in order to decrease thechances of developing it.
Symptoms of lung cancer
In the first stages, the lung cancer usually does not show any symptoms but the signs appear when the cancer has already progressed considerably. Sudden new persistent cough, coughing up the blood and shortness of breath, as well as wheezing, hoarseness and pain in the chest are the most typicalsigns of this serious lung disease. Furthermore, the people who developed thelung cancer may also experience bone pain, headache and unexplained weightloss.
Nowadaysthe medicine has significantly advanced so that the treatment of the lung canceris made possible. The procedures used in the treatment of the lung cancer aresurgery, chemotherapy and radiation.
Lungcancer survival rate
Thetreatment of the lung cancer is more difficult than the treatment of othercancers because diagnosis of the lung cancer is difficult. In the majority ofcases, the lung cancer is diagnosed in the progressive stages when it isalready too late and when it is fatal for the patient. For that reason, the survival rateamong the patients with the lung cancer is considerably low if we compare itto the survival rate among the patients with some other type of cancer.
Whatwill be the lung cancer survival rate depends on the stage at which the lungcancer is detected and this disease has four different stages. Furthermore,the lung cancer survival rate also depends on the type of the cancer, as well ason the general health of the patient since the survival rate decreases if thepatient already suffers from some other disease as well.
Whenthe cancer is detected in the first stage, the survival rate is about 10 yearsin almost 90% of the cases. The survival rate among the patients with the secondstage of lung cancer is five or more years in almost 50% of cases. Furthermore,the lung cancer survival rate when it is detected in the third stage is about13%, while in the fourth stage of the lung cancer, the survival rate is onlyabout 2%.
