I am a 23 year old male and have what appears to be an enlarged Right apical lymph node. Rubbery, definitely movable (can move it from subclavicular to supraclavicular), non-tender, about 2cm in diameter. I have a family history of colon cancer and have read the colorectal cancers can metastasize to the apical lymph, although nothing that i read has been specific on left or right.
Thanks for your question on Chat Doctor. Yes, you as right. Colorectal cancers can spread in cervical lymph nodes but not as a primary symptom.  It spreads somewhat late in the course of disease. First patient develops intestinal symptoms like pain, blood in stool etc. and then patient can have distant metastases like in lymph node. So in my opinion you should not worry much about malignant lesion as you are not having abdominal symptoms. But you should definitely get done biopsy of this lymph node to reach the diagnosis. You may have infective lymph node. So get done biopsy and don't worry about malignancy.
