Does Tdap Vaccination Cause The Lymph Nodes In Neck To Swell?

How likely is it that a tdap vaccine could cause a supraclavicular lymph node as well as another lymph node about an inch higher toward the neck to swell and become palpable? I noticed them because the area was sore about 4-5 days later and I rubbed it and that s when I noticed but could it just be coincidence? They were not notceable last year during an exam. They are both about the size of a pea/raisin, but depending on the direction I touch them from they can seem slightly larger than this. The location makes also me wonder/worry if it is related to the injection at all or possibly (hopefully) an unrelated infection, or worse, a sign that some sort of cancer is in the nodes. What are the risks of waiting for a few months before getting an excisional biopsy assuming it were to turn out to be cancer? However slim or common the percentages may be I want to know the impact waiting would have on treatment and recovery prognosis assuming it were cancer.
