###Human: Kindly tell me if there is any alternative to bronchoscopy to get tissue for testing cancer. ###Assistant: Hi. Confirmation of any form of cancer is by biopsy only when the malignant cells are visualized under a microscope and reported to be positive. Rest of the radiological test like HRCT and MRI are highly sensitive but not specific. I am assuming that the cancer was either diagnosed by cytology or radiology in her case and they did a bronchoscopy to get the tissue they suspected of being malignant. Usually, broncoscopy is done under anesthesia and does not cause any complication. Probably the cancer had been more advanced in this case or the patient's physical condition was poor but anyhow there is no other way than broncocopic tissue examination to confirm the diagnosis.
