Surgical biopsy in lymphoma

The term 'lymphoma' describes malignant lymphoproliferative diseases that originate from B- and T-cells in the lymphatic system. The majority of lymphomas arise from lymph nodes, while some may originate in extranodal sites. Lymphoma is a common cancer, affecting approximately 4000 people in Australia per year, and constituting 4% of newly diagnosed cancers. Lymphoma is primarily a disease of adults, and is the sixth most common cancer in men, after prostate, colorectal, lung, melanoma and bladder, and the fifth most common cancer in women, after breast, colorectal, melanoma and lung.
