I have two lumps that came up at the same time week ago today. One is pea sized and located under my chin (directly in the middle). It started off much larger but is now shrunk down to pea size. The other one is on my neck slightly off to the right of the adam's apple. The one on my throat is about about an inch around and is bigger on some days than others. My sister passed of pancreatic cancer in 2001. Can someone please help me? I am very concerned.
