[|Human|] I smoked for 5 years, then cold turkeyed it for 5 years, then smoked for 2 1/2 more years, and have just quit again. My lymph-nodes are swollen in my neck and I have canker sours in my mouth. It is also hard to swallow. I am 27 years old and a male. Should I be worried about cancer with these symptoms?
[|AI|]  Probably yes. The symptoms that you have indicated may be some warning signs of cancers or cancers per se. I would advise you to meet a physician nearby and get thoroughly checked for signs of cancers or associated diseases which may be termed as pre malignant conditions. I would strongly advise you to quit smoking and other ill habits and follow health diet and hygienic food with more vegetables. Furthermore, I hope this clarifies your queries and would be glad to answer more if any. Regards.
