A biopsy is a minor procedure where your doctor removes a small sample of tissue (e.g., a skin mole, a lymph node, or a polyp) so it can be analyzed by our expert pathologists. This test is the gold standard—the only way to get a definitive diagnosis for many conditions. Our experts will examine the tissue's cellular structure under a microscope to identify the precise cause of the issue, whether it's inflammation, an infection, a benign (non-cancerous) growth, or a malignancy. This is the single most important step to move from uncertainty to a conclusive, actionable answer, ensuring you get the exact treatment you need.
