Fine particulates sulfate aerosols which are usually released in car exhaust fumes and other outdoor air pollutants account for roughly 1.5% of lung cancer cases. Other causes include, asbestos exposure, exposure to radon gas, ionizing radiation, some toxic gases, rubber production and crystalline silica dust.
The symptoms that you can use to identify lung cancer are divided into two. They are Respiratory symptoms and Systemic symptoms. The former includes, cough, coughing up blood, or blood-colored phlegm, recurrent respiratory infections (bronchitis or pneumonia), wheezing, shortness of breath.
The systemic symptoms can include tiredness, unexplained weight loss, fever, or clubbing of the fingernails. The cause of these symptoms can range from the direct effect of the primary tumor, the effect of metastases, to hormonal disturbances.
After the symptoms have been identified, lung cancer can be diagnosed using five investigative steps. A chest radiograph can be performed to see the exact cause of the symptom. However, CT imaging is necessary to provide additional information about the type and disease extent. Next, bronchoscopy, or in some cases, CT-guided biopsy will be used to sample the tumor for histology.
Since tobacco smoking accounts for majority of the cases of lung cancer, the obvious step would be to find a way of smoking cessation through some form of policy intervention. Regular screening is also a good idea.
Lung cancer can be managed through surgery, radiotherapy, chemotherapy. The preferred treatment depends primarily on the cancer’s specific cell type, the patient’s performance status, and how far the cancer has spread.
