Be seen today
If you have already been diagnosed, contact your lymphoma team promptly about new lumps, worsening symptoms or treatment side effects.
During chemotherapy or other immune-suppressing treatment, fever, chills or feeling suddenly unwell requires urgent advice because infection can become serious quickly.
Follow the temperature threshold and contact instructions provided by your team.

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you have a painless lump that persists or grows, repeated unexplained fevers, drenching night sweats, unplanned weight loss or ongoing symptoms that concern you.
These symptoms often have causes other than lymphoma, but they should be assessed.
Every sign above is quoted from the sofidex article on Non-hodgkin lymphoma. If you are not sure, err upward — it is always reasonable to be checked.
