Non-Hodgkin’s lymphoma

In 2017 in Northern Ireland, 344 people were newly diagnosed with non-Hodgkin’s lymphoma. There are many different types of non-Hodgkin’s lymphoma. Some grow very slowly and may not need treatment for months or years. Other types grow quickly and need treatment soon after diagnosis. The various types of non-Hodgkin’s lymphoma are divided into high-grade (fast growing) and low-grade (slow growing). Overall, most cases of non-Hodgkin’s lymphoma are considered very treatable. 

Signs and symptoms

The most common symptom of non-Hodgkin’s lymphoma is one or more painless swellings in the:

  • neck;
  • armpit;
  • groin.

Each swelling is an enlarged lymph node. Other general symptoms include:

  • heavy sweating at night;
  • temperatures that come and go with no obvious cause;
  • losing a lot of weight (more than one tenth of your total weight);
  • some people may also have unexplained itching. 

If you have a swollen lymph node that does not go away after 6 weeks, you should see your doctor.
