Hello, I have a swollen left lymph node located along my jaw line about a centimetre from my ear. it has been swollen for around two months, staying around the same size, and im worried as to what it could be. I am 15 years old, and have a history of cancer in the family, while I myself have chronic bronchitis , but haven t experienced any symptoms for some time. I was just wondering as to if this could be related to that problem or if it could be cancerous?
