Biopsy Principles in MSK Oncology
Biopsy is critical for diagnosis but must follow strict oncological principles. Plan biopsy with final surgery in mind; incision should be longitudinal and in line with resection. Avoid contamination of uninvolved compartments and neurovascular structures. Prefer core needle/incisional biopsy; excisional only for small superficial masses. Send adequate tissue for histopathology, culture, cytogenetics.
