1. Pre-operative Evaluation: The patient undergoes a series of tests, including blood work and imaging studies, to ensure they are fit for surgery.
2. Anesthesia: Depending on the location and size of the tissue to be sampled, either local or general anesthesia is administered.
3. Tissue Removal: The surgeon makes an incision and removes the suspicious tissue. In some cases, the surgeon might also remove nearby lymph nodes to check for the spread of cancer.
4. Closure: The incision is closed with stitches and covered with a sterile dressing.
