Biopsy
To diagnose lymphoma you will need a biopsy. A biopsy is a procedure to remove part, or all of an affected lymph node and/ or a bone marrow sample. The biopsy is then checked by scientists in a laboratory to see if there are changes that help the doctor diagnose lymphoma.
When you have a biopsy, you may have a local or general anaesthetic. This will depend on the type of biopsy and what part of your body it is taken from. There are different types of biopsies and you may need more than one to get the best sample.
Core or fine needle biopsy
Core or fine needle biopsies are taken to remove a sample of swollen lymph node or tumour to check for signs of lymphoma.
Your doctor will usually use a local anaesthetic to numb the area so you don’t feel any pain during the procedure, but you will be awake during this biopsy. They will then put a needle into the swollen lymph node or lump and remove a sample of tissue.
If your swollen lymph node or lump is deep inside your body the biopsy may be done with the help of ultrasound or specialised x-ray (imaging) guidance.
You might have a general anaesthetic for this (which puts you to sleep for a little while). You may also have a few stitches afterwards.
Core needle biopsies take a bigger sample than a fine needle biopsy.
Excisional node biopsy
During this procedure, a surgeon will remove the whole lymph node or lump and send it to pathology for testing. You may have a general anaesthetic which will put you to sleep for a little while, so you stay still and feel no pain.
You will have a small wound with a few stitches, and a dressing over the top.
Stitches usually stay in for 7-10 days, but your doctor or nurse will give you instruction on how to care for the dressing, and when to return to have the stitches out.
Excisional node biopsies are more reliable than fine needle or core needle biopsies for diagnosing lymphoma.
Blood tests
Blood tests are taken when trying to diagnose your lymphoma, but also throughout your treatment to make sure your organs are working properly and can cope with our treatment.
Results
Once your doctor gets the results from you blood tests and biopsies they will be able to tell you if you have lymphoma and may also be able to tell you what subtype of lymphoma you have. They will then want to do more tests to stage and grade your lymphoma.
