Is there a good chance my swollen lymph node is not cancer? Please help?

Hi Gold Diamond, I believe you will be fine. The sides of the neck have several usually small lymph nodes that are not noticeable. ANYTHING that causes an infection in the nose or throat or head area commonly causes inflammation. Rarely is it cancer, especially in a young woman such as you. Each lymph node contains many protective lymphocytes which rapidly increase and are the body's protective response. As the lymphocytes increase, they stretch the tight capsule of the node and often cause pain with enlargement. As the infection begins to disappear, the nodes will slowly shrink again, often taking 6 to 8 weeks, Cancer does not "shrink" as you have experienced. Hence I believe you have a slowly shrinking, returning to normal lymph node. You probably know that lung conditions such as asthma and bronchitis can easily lead to infection from time to time.
