Diagnosis of neoplastic conditions often involves a combination of clinical evaluation, imaging studies, and biopsy. Imaging techniques such as X-rays, CT scans, MRI, and PET scans help visualize the location and extent of the tumor. A biopsy, where a tissue sample is taken for microscopic examination, is crucial for confirming the diagnosis and determining the histological type of the neoplasm. This information is essential for guiding treatment decisions.
