Hi doctors. i have back and groin pain. i also have gas. i have had a ct scan done in sept. they found swollen nodes in my chest. lymphoma?

DDx: Some symptoms -- eg "gas", back pain are common and occur in the majority of the population. Enlarged lymph nodes can be from a variety of causes including lymphoma and many non-cancerous causes. It needs evaluation to develop a differential diagnosis (ddx).

Hard to say...: The diagnosis of lymphoma is very complex and relies on a constellation of clinical signs and symptoms including unexplained weight loss, night sweats, lack of appetite, fatigue, progressively enlarging lymph nodes, progressively enlarging liver and/or spleen, etc. Ultimately, a lymph node biopsy is necessary in order to confirm or rule out the diagnosis. Consulting your physician is recommended.
