Cancer is found (1) throughout one or more organs that are not part of a lymphatic area (lymph node group, tonsils and nearby tissue, thymus, or spleen) and may be in lymph nodes near those organs; or (2) in one organ that is not part of the lymphatic area and has spread to organs or lymph nodes far away from that organ; or (3) in the liver, bone marrow, cerebrospinal fluid (CSF), or lungs (other than cancer that has spread to the lungs from nearby areas).
