I have noticed some tumours on my body (on my hand and my back) which are not properly visible, but I can feel that when I touch on that. I went to a surgery Dr. and he said that it's a cholesterol thing and no need to worry and if I want I can remove it by a surgery. Those tumours are neither aching nor growing. I happened to read an article which says tumours like this are symptoms of cancer. What am I supposed to do now? Dr. says its cholesterol. But I'm still scared.
