Collection and usage attributes

Collection methods:Help on this term

For cancer registries, collection of this data item should only be from pathology reports relating to initial diagnosis and not for recurrent or metastatic tumour.

Comments:Help on this termSentinel lymph nodes are the first nodes that filter fluid draining away from the area of cancer. The presence of cancer cells in the lymph nodes indicates that cancer cells have already spread outside the primary site and may have spread to other areas of the body. This is important for cancer staging and treatment options.
