Hodgkin lymphoma

Also called Hodgkin's disease

Hodgkin lymphoma is an uncommon cancer that develops in the lymphatic system, part of the body's immune system. It most often affects young adults and people over 75. The most common symptom is a painless swelling in a lymph node, usually in the neck, armpit or groin.

What it is

It is one of the most treatable types of cancer. Most people are cured.

Treatment usually involves chemotherapy, sometimes followed by radiotherapy. Long-term follow-up checks for late effects of treatment.

Common signs

  • A painless swelling in the neck, armpit or groin
  • Night sweats
  • Unexplained weight loss
  • High temperature
  • Itching
  • Persistent cough or breathlessness

How it is usually diagnosed

  • A lymph node biopsy
  • Blood tests
  • CT and PET-CT scans
  • Bone marrow biopsy, sometimes

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Biopsy and histology reports
  • Scan reports, including staging
  • Blood test results
  • Treatment summaries and follow-up letters

Questions to ask your doctor

  • What stage is my lymphoma?
  • What treatment do you recommend?
  • What late effects should I watch for after treatment?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • High fever or feeling very unwell during chemotherapy: call your cancer care team or 112 straight away
