Get it checked out! Watch it closely, and if you feel that there has been a change GET IT CHECKED OUT! If you can get a biopsy, do that. The only definite way to know what something on the inside of your body is....take it out... Try not to stress too much over this, but pay attention to your body. If you haven't already done so, read a few good books on cancer, and steps you can take to help reduce the risk. A big one is eat more fruits and vegetables, cut back on white sugar and processed and fried foods. But remember, it could be nothing. The only way to know is to check it out. And when the tests show that it is nothing to worry about, if it changes in the future, check it out! Don't just let it go without following it up. I had squamous cell carcinoma of the head and neck. Mine started with a sore throat, flu like symptoms, and then a lymph node on the side of my neck grew to the size of a grapefruit. I have never been a smoker, so the doctors thought it was just my lymph nodes making white blood cells to kill the infection. I kept going back to the doctor (saw several) over a 5 month period before I finally saw a doctor that said it was not normal and sent me to ENT, who immediately did a biopsy. It came back cancer, and a week later I had my first surgery. The point is, I kept going to the doctor to check it out. I am alive because of my persistence and God's grace. So, it is your body. Check it out. Good luck and God bless.
