question: Hi,I've had a lump above my collarbone that I can move around for the best part of 4 years. It's never caused me any pain, I have never had any symptoms and it's exactly the same size now as when I first noticed it. Is it likely to be a Lipoma or Lymphoma? How quickly can a cancerous node grow? am I right in thinking that if it was cancerous it would have grown considerably in 4 years?Christ
