Introduction

Palpation, inspection, percussion, and auscultation are basic physical examination methods that can provide an initial assessment of pulmonary nodules. Chest X-ray can show the general structure of the lungs and detect obvious abnormalities, including larger pulmonary nodules. Compared to X-ray, CT scan provides images with higher resolution. Laboratory tests include sputum culture.

Physical exams can usually detect lung nodules, and it is recommended to undergo examinations under a doctor's guidance. If any physical discomfort occurs, it is advisable to seek medical attention at a hospital promptly and follow the doctor's instructions for treatment.

If your physical examination includes a chest X-ray or CT scan, especially a high-resolution CT scan, even small lung nodules have a high probability of being detected. These tests provide detailed images of the lungs and help in the early detection of abnormalities.

Is Maytenus effective for lung nodules?

Maytenus is a plant, and some traditional practices have mentioned its potential anti-inflammatory and mass-dispersing effects. However, these claims lack sufficient clinical evidence. Currently, there is no authoritative evidence indicating that Maytenus can directly reduce or eliminate pulmonary nodules, and it has not been included in standard treatment guidelines for pulmonary nodules. Its effects on nodules remain largely theoretical.
