World Lung Cancer Day Trivia Quiz

A persistent cough is a common symptom of lung cancer. This is because lung cancer can cause irritation or blockage in the airways, leading to a chronic cough that does not go away. Other symptoms such as fatigue, headaches, and abdominal pain are not typically associated with lung cancer. It is important to note that these symptoms can also be caused by other conditions, so it is always best to consult a healthcare professional for a proper diagnosis.

Smoking tobacco is the leading cause of lung cancer. Numerous studies have shown a strong association between smoking and the development of lung cancer. Tobacco smoke contains numerous harmful chemicals, including carcinogens, which can damage the cells in the lungs and lead to the formation of cancerous tumors. The more cigarettes a person smokes and the longer they smoke, the greater their risk of developing lung cancer. Quitting smoking is the most effective way to reduce the risk of lung cancer and improve overall health.

Lung cancer screening with low-dose CT scans has shown a reduction in lung cancer mortality in high-risk individuals. This screening method allows for the early detection of lung cancer in individuals who are at a higher risk due to factors such as smoking history or exposure to certain substances. By detecting lung cancer at an early stage, it is possible to initiate treatment earlier, leading to improved outcomes and reduced mortality rates. This intervention has been proven effective in reducing lung cancer deaths and is recommended for individuals at high risk.

The TNM staging system is commonly used to determine the extent of lung cancer. TNM stands for Tumor, Node, and Metastasis, and it assesses the size and spread of the tumor (T), whether the cancer has spread to the lymph nodes (N), and whether it has metastasized to other parts of the body (M). This system provides detailed information about the stage of the disease, which helps in determining the appropriate treatment and prognosis for the patient. The SEER staging system is a database used to collect cancer data, while the AJCC staging system is a classification system that incorporates the TNM system. The GGO classification system is not specifically related to lung cancer staging.

Small cell lung cancer is most commonly associated with smoking because it is strongly linked to tobacco use. This type of lung cancer is highly aggressive and spreads quickly, making it more likely to be diagnosed in heavy smokers. Small cell lung cancer is often found in the central areas of the lungs and is typically caused by the inhalation of carcinogens present in tobacco smoke. It is important for smokers to be aware of the increased risk of developing small cell lung cancer and to take steps to quit smoking and reduce their chances of developing this deadly disease.

Computed tomography (CT) scan is commonly used for lung cancer diagnosis because it provides detailed images of the lungs, allowing doctors to detect abnormalities such as tumors or nodules. CT scans can show the size, shape, and location of a lung tumor, as well as whether it has spread to nearby lymph nodes or other organs. This imaging technique is particularly effective for detecting small lung cancers that may not be visible on a standard X-ray. MRI and PET scans can also be used in lung cancer diagnosis, but CT scans are generally the preferred choice due to their higher resolution and ability to provide more accurate information.

The primary treatment approach for early-stage non-small cell lung cancer is surgery. Surgery involves the removal of the tumor and surrounding tissue. It is often the first-line treatment for early-stage lung cancer because it offers the best chance of cure. Chemotherapy, radiation therapy, and immunotherapy may also be used in combination with surgery or as alternative treatment options depending on the specific characteristics of the tumor and the patient's overall health. However, surgery remains the primary treatment approach for early-stage non-small cell lung cancer.

Adenocarcinoma is the correct answer because it is a type of lung cancer that commonly occurs in nonsmokers. It is more likely to develop in the outer regions of the lung and is associated with genetic mutations rather than smoking. Adenocarcinoma is the most common type of lung cancer overall and is often diagnosed at an advanced stage. It tends to grow slower than other types of lung cancer and has a better prognosis.

Exposure to radon gas is a major risk factor for developing lung cancer besides smoking. Radon is a naturally occurring radioactive gas that can be found in soil, rocks, and water. When it is released into the air and inhaled, it can damage the cells in the lungs and increase the risk of developing lung cancer. Radon gas exposure is a significant concern, especially in areas with high levels of radon, such as in homes with poor ventilation or in underground mines. It is important to test homes for radon levels and take necessary measures to reduce exposure to this harmful gas.

TP53 mutation is commonly associated with small cell lung cancer. TP53 is a tumor suppressor gene that helps regulate cell division and prevent the formation of cancerous cells. Mutations in this gene can disrupt its normal function, leading to uncontrolled cell growth and the development of cancer. Small cell lung cancer is known to have a high frequency of TP53 mutations, making it a common molecular alteration in this type of cancer.
