What is retroperitoneal lymph node biopsy by needle aspiration?
The doctor may suspect that your retroperitoneal lymph nodes are not working well or may have cancer in them. Lymph nodes are oval-shaped organs found throughout the body that make lymphocytes and monocytes, which are cells in the lymph fluid. They filter the lymph fluid, keeping bacteria out of the bloodstream. They may also trap cancer cells and develop cancer themselves, called lymphoma. An alternative would be to choose not to have treatment, recognizing the risks of your condition. You should ask your doctor about this choice.
