Hey, is it normal for both of my occipital lymph nodes to be immovable? i've read online that this is a sign of having cancer... but my nodes have not changed and they have both remained pea sized for 2 months. i am also 16 and quite slim?

Lymph nodes are normal benign structures present in several area including sub-occipital area. The nodes can enlarge due to many conditions such as infections of the skin. On rare occasions the nodes can become canerous or cancer can spread into nodes from other sites in the body. Lymph nodes are considered benign unless they are growing in size. They require attention if their size is 1Cm or more

You may feel the nodes every couple of weeks, if any of the lymph glands doubles in size, becomes painful, ulcerates, or other nodes become enlarged, or you develop fever, or lose weight, you should see a doctor. Wish you good health!
