Lack of investigative tools and cultural beliefs which detest autopsy hamper correct statistics of lung cancer cases in Nigeria. However, recent studies have revealed an increasing incidence of this lesion in the country. 42 percent of the males who were detected with lung cancer in research that was conducted had a history of smoking cigarettes. Moreover, these cases were predominantly adenocarcinoma of the lungs where treatments are largely palliative. High prevalence of cigarette smoking among Nigerian males calls for generating awareness about risk factors causing lung cancer. Moreover, lack of treatment facilities providing lung cancer surgery, radiation therapy and chemotherapy have also contributed to the extent of the problem as such.
Lung Cancer is a Major Killer Disease
According to figures let out by World Health Organization (WHO), there is about 1.4 million deaths worldwide occurring every year due to lung cancer. Moreover, there is an increase in cases of lung cancer in developing countries due to increase of use of tobacco. It is also a recognized fact that mortality worldwide due to lung cancer bears a significant history of smoking, especially among men above 50 years of age. Moreover, it has also come to notice that while incidence of lung cancer has been declining in men over the last couple of decades, there are more cases nowadays which have been recorded among women.
Smoking is a Leading Risk Factor for Lung Cancer
While link between lung cancer and smoking tobacco cannot be overemphasized, studies have revealed that cigarette smoke contains more than 73 well known carcinogens including 1, 3-butadiene and benzopyrene. This is why smoking, including passive smoking amounts for almost 80 to 90 percent of lung cancer cases. Moreover, since passive smoking is equally vulnerable, if not more, people living with smokers have 20 to 30 percent increased risk of developing lung cancer when compared to others. In order to curb the menace of lung cancer among passive smokers, most countries have banned smoking in public places. WHO has additionally, called upon governments across the world to place a complete ban on advertisement of cigarettes and tobacco-products.
Signs and Symptoms of Lung Cancer
Respiratory signs and symptoms produced by lung cancer include cough which is sometimes also accompanied by blood and chest pain. Airflow may also be obstructed and cause difficulty in breathing if lung cancer has grown into the airways. Systemic symptoms among lung cancer patients include fatigue, fever, poor appetite and weight loss. However, it is also important to note that almost 10 percent of lung cancer patients fail to show any signs and symptoms at the time of diagnosis while the disease is only discovered during routine chest radiography.
Treatment Options for Lung Cancer
Most common treatment options for lung cancer include lung cancer surgery, chemotherapy, radiation therapy or palliative care. There are many types of lung cancer surgery. Lung cancer surgery which involves removing one lobe is known as lobectomy. Removing two lobes of lung during lung cancer surgery is known as bilobectomy and removal of the whole lung as pneumonectomy. Other types of lung cancer surgeries which are performed for patients include wedge resection, segmentectomy and sleeve resection. When lung cancer surgery also involves removal of associated lymph nodes, it is known as lymphadenectomy. Typically, chemotherapy is recommended after lung cancer surgery when lymph nodes are involved. Radiation therapy for lung cancer is becoming more common nowadays with development of advanced techniques. Radiation therapy like CyberKnife radiosurgery which can precisely deliver radiation on moving tumors without damaging the surrounding healthy tissue is preferred by many doctors and patients. Chemotherapy is an essential component of treatments in advanced stages of the disease. Lung cancer which has spread to other parts of the body from lungs requires systemic treatments like chemotherapy.
