Test on Lung Cancer: Overview, Diagnosis, and Treatment

Question 1: The majority of lung cancer patients experience significant constitutional symptoms such as anorexia and weight loss when the disease is still in its early stages.

A. Ano

B. Ne

Explanation: Constitutional symptoms like anorexia, weight loss, and weakness are usually indicative of advanced disease, not early stages.

Question 2: According to the provided study materials, which of the following is identified as a significant risk factor for lung cancer?

A. Exposure to high levels of radon

B. Chronic Obstructive Pulmonary Disease (COPD)

C. Frequent consumption of processed foods

D. Second-hand smoke

Explanation: The study materials list radon (high levels found in basements), COPD (an independent risk factor), and second-hand smoke as risk factors for lung cancer. Frequent consumption of processed foods is not mentioned as a risk factor.

Question 3: A solitary pulmonary nodule is typically first discovered through a Chest CT scan.

A. Ano

B. Ne

Explanation: Solitary pulmonary nodules are usually discovered incidentally on a CXR performed for another reason. Chest CT is then performed as the test of choice for diagnosis after initial discovery.

Question 4: A solitary pulmonary nodule is commonly found incidentally during a chest X-ray performed for a different medical purpose.

A. Ano

B. Ne

Explanation: The study materials state that a solitary pulmonary nodule is 'Usually discovered incidentally on a CXR performed for another reason'.

Question 5: According to the study materials, which calcification pattern in a solitary pulmonary nodule suggests malignancy?

A. Dense, central calcification

B. Eccentric asymmetric calcification

C. Homogeneous peripheral calcification

D. Laminated calcification

Explanation: The study materials state that 'Eccentric asymmetric calcification suggests malignancy,' while 'Dense, central calcification suggests benign lesion.'
