multiple choice question
often when a cancerous tumor is surgically removed from a patient, surrounding lymph nodes are removed as well. why?
cancers that metastasize will travel to nearby lymph nodes first.
cancer always forms in lymph nodes first.
lymph nodes, like your appendix, serve no real function.
cancers found in lymph nodes are the most deadly.

Explanation:

Cancer cells often spread (metastasize) to nearby lymph nodes first. Removing them helps check for and prevent further spread. Cancer doesn't always form in lymph nodes first, lymph nodes have important immune - related functions, and not all cancers in lymph nodes are the most deadly.

Answer:

Cancers that metastasize will travel to nearby lymph nodes first.
