i noticed some guilt there dont feel guilty please actually a lot of doctors when they find swollen lymph nodes they dont get alarmed because most of the time are not dangerous even though you had it checked this could have have the same outcome  for example i dont know if i could have cancer ive had 1 swollen lymph node since 2019 and doctor assumed that it was because of an infection after treatment the lymph node is still there they did an ultrasound of it and even though it looked ok sometimes an ultrasound cant show whether is benign or not you need to take a sample of it and that is pretty pricey so some doctors dont even ask you to do it until you have other symptoms so 1 year after im okay lymph is there i was sent home telling me sometimes they just stay there im just trusting the docs   this could have been you a lot of people dont realize they have cancer even if they do everything as they should dont feel guilty please we do the best we can
