<s>[INST] Hello. Last week I noticed a hard lump on my forehead about 5cm above the middle of my left eyebrow. It is not sore and is under the skin. It's about the size of a very large pimple. It has not gone down or become bigger.I am very concerned about it being cancer. Thank you. [/INST] you need to understand clearly that all lumps are not cancers. non cancerous lumps are more common especially those under the skin. mobile lumps are usually non cancerous. but if the lump is growing in size or changing its characteristics it is better you see an oncologist </s>
