I have small flexible lump under chin. my doc said its just a swellen lymph node. but i am worried about cancer. plz help. i have phobia of cancers?

If you have a: Fear of cancer that is impacting your quality of life would encourage you to consider cognitive behavioral therapy or psychotherapy.

Watch it for changes: The lumps are not worrysome if they are small(less than 2cm/ or half inch) in size. If they are bigger or grow in size while you watch them for 1 to 2 months, then you have to get suspicious and show them to you doctor. An increase in size by 50% would be of concern, small changes are not of much concern. So check it and estimate/measure the size once every 2-3 weeks and you will know what to do.
