A wide range of diagnostic evaluations may be used to determine or confirm a lung cancer diagnosis. They include X-rays, lab tests, a CT angiogram, CT scan, biopsy, bronchoscopy, lung nodule analysis, PET scan and endobronchial ultrasound. Advances in technology have led to more accurate and thorough diagnostics for lung cancer and can help you develop an appropriate treatment plan for your type and stage of lung cancer. That is why it is important to find a doctor and facility with access to advanced diagnostic tools to evaluate the disease—before, during and after treatment.
