My dad is awaiting his second surgery in 6 months for oral cancer. Today he discovered a small lump, similar to the size of a pimple under his right armpit. I know this area has many lymph modes which makes me worry about spread. He was recently diagnosed with a second primary on his right back oral tongue with some possible node involvement (he already had a neck dissection for surgery number 1 in May). Should I schedule him to see the doctor? Is this something we should we concerned about? Im just worried because its the right side and he has a new cancer on the right side. I should note he got a flu shot on Thursday.

Does the concern ever end?
