Further tests for non Hodgkin lymphoma
If lymphoma cells were found in the lymph node you had biopsied your doctor will want you to have more tests. These tests are to find out whether the lymphoma has spread. The doctors will need to know which parts of your body are affected.
Tests occasionally used in lymphoma
Some people have one or two other tests, as well as the ones above. You may have
After the tests
Waiting for results is a very anxious time for most people. While you are waiting it may help to talk to your clinical nurse specialist or a close friend or relative about how you are feeling. Or you may want to contact a cancer support group to talk to someone who has been through similar experiences.

If there are lymphoma cells in the lymph node you had biopsied your doctor will want you to have more tests. These tests are to find out whether the lymphoma has spread. The doctors will need to know which parts of your body are affected.

These tests will be repeated every so often during your treatment to check how you are doing.
Throughout your treatment you will be asked to have blood tests. These are to check
- Blood cell levels
- How well your liver is working
- How well your kidneys are working
- Blood levels of substances such as calcium and proteins
LDH stands for lactate dehydrogenase. This is a normal substance in the blood but it is at higher than normal levels in some types of cancer.
You may have a CT scan of your chest, abdomen or pelvis. This is a type of X-ray that takes pictures from different angles. These feed into a computer and form a detailed picture of the inside of your body. The scan shows up any lymph nodes affected by lymphoma. The scan technician or doctor may ask you to drink a liquid called contrast medium before the scan. The liquid makes the scan pictures of your gut clearer. But unfortunately, it may give you diarrhoea afterwards. For more information about having a CT scan, look at the cancer tests section.
PET scans are a newer type of scan. PET scans are not useful for all types of lymphoma. Your doctor can tell you more about this. But they are being used more often these days for people with high grade lymphoma. They are useful for staging lymphoma and seeing how well treatment has worked. They show the difference between tissues that are actively growing (like cancer) and an old injury or scar. A CT scan can show an enlarged lymph node. It may not be enlarged because of cancer, but with fibrous scar tissue from an infection. A PET scan can also show if any remaining lumps are lymphoma that has not responded to treatment. There is more information about having a PET scan in the cancer tests section.
This test is to see whether there are cancer cells in your bone marrow. The doctor takes a tiny sample of bone marrow cells to look at under a microscope. The test only takes a few minutes and you can have it as an outpatient. There is more about having a bone marrow test in the cancer tests section.
As well as the tests above, some people need one or two other tests. You may have any of these tests
Your doctor may ask you to have a test called a lumbar puncture. This is to see whether there are any lymphoma cells in your cerebrospinal fluid (CSF). The CSF is fluid that circulates around your brain and spinal cord. There is more about having a lumbar puncture in the cancer tests section.
This is a test to look inside the body. An endoscope is a long thin bendy tube with a camera and a light inside it. You can have an
- Endoscopy of the stomach and food pipe (oesophagus)
- Endoscopy of the upper airways
- Endoscopy of your bowel and back passage (rectum)
The doctor puts the tube into your mouth and down your throat. The doctor examines the inside of your food pipe and stomach. If necessary, the tube can look into your small bowel as well.
This test is usually done while you are awake. But to make you comfortable you may have a local anaesthetic sprayed onto the back of your throat. You may also have a sedative and will probably not remember the test afterwards.
This is also called a bronchoscopy. If you have enlarged lymph nodes in your chest, your doctor may want to look inside your airways using an endoscope. This test is usually done while you are awake. But to make you comfortable you may have local anaesthetic sprayed onto the back of your throat. You may also have a sedative beforehand and will probably not remember the test afterwards. The tube goes up your nose or into your mouth. The doctor looks at the inside of your airways and takes samples of tissue (biopsies) if necessary.
Endoscopic tests of your bowel have different names depending on which part of the bowel is being looked at. A proctoscopy just looks at the back passage, a sigmoidoscopy looks at the lower part of the large bowel, and a colonoscopy looks at the whole of the large bowel.
You shouldn't need a sedative for a proctoscopy or a sigmoidoscopy. But you will probably have sedation before a colonoscopy, because this is more uncomfortable. Your doctor will ask you to lie on your side and will pass a flexible tube into your back passage and up into your bowel. As the tube bends easily, it can pass around the curves in the bowel. The light inside the tube helps the doctor to see any problem areas or swelling. Your doctor can take photographs and biopsies of the bowel lining during the test.
There is more detailed information about having these tests in our bowel cancer tests section.
These scans may be done to give the doctor a clearer idea of where the lymphoma is in your body. MRI scans can sometimes show up soft tissue more clearly than CT scans.
You will have to go back to the hospital when your test results have come through. But this will take a little time, maybe a week or so. This is a very anxious time for most people. While you are waiting for results, it may help to talk to your clinical nurse specialist or a close friend or relative about how you are feeling. Or you may want to contact a cancer support group to talk to someone who has been through similar experiences.
