Husband has large nodes above collar bone weight loss fatigue and bloating . won't go to dr. if its something serious how fast would it progress?

Serious: Should not be ignored-i will be glad to discuss with your husband; however, the symptoms you describe require immediate medical evlauation.

Potentially: Must be seen for evaluation. The longer you wait, the issue may become worse and more difficult to evaluate and treat. Best wishes!

Serious!: Lymph nodes above the collar bone are very concerning, and are often a sign of a serious disease, such as lymphoma or gastric or pancreatic cancer. It is difficult to say how quickly it would progress without a tissue diagnosis (he would need a biopsy). The longer he waits to get a diagnosis, the more likely he is to have a poor prognosis and fewer treatment options.
