Im a 13 year old boy with a lump or knot above my left collar bone. Is this a sign of cancer?
Hello! A lump is not necessary a sign of cancer. A lot of times can be fat tissue, a swollen lymphonode, simple things. But there is also the chance of being something worse. every time you have a lump it means you need to let it be checked by a md. And always as soon as possible. Big chance that it will be something not serious, but we don't take any risks with lumps. Also surfing on internet won’t solve the problem and will make you more worried. The consistence, mobility, exact location of the lump needs to be felt by a physician. Take care.
