Question: I have a couple of questions about my lymph node on my neck that is swollen. I have one swollen lymph node on my neck under my jaw. I found it a month ago and at first it was about 4cm in size. Now it is under 1.2 cm in size and i feel it s getting smaller. But I still worry about it everyday. During the first month of it I was so afraid it was cancer and measured it at least 50 times a day. I weighed myself constantly to see if there was any weight loss. THe first couple of weeks it was bad I thought for sure i had cancer. I didn't eat or anything. Now A few weeks later it got smaller and I calmed down a bit. But this week I started being self conscious and watching what I eat and realized that I have less of an appetite than I did before and I also started to weight myself more and my weight changes from 208 to 212 then back and forth. I'm scared again and feel like I have cancer. I have no insurance so I can't go to the doctors. I have an abscess in my tooth which I believe to be causing the swollen lymph node.

SO my questions are.
What are the chances this is cancer?
AM i just being paranoid about having cancer?
Should I be concerned about any of this?
How long is the lymph node going to stay?
Is it normal for the lymph node to make my neck look slight bigger on one side than the other since it is near my jaw and such?
Am I going to die?
Should i be afraid?
Am I being rational about all of this or just afraid?
Please answer all the questions.
