It might also have spread to other nodes that are on the same side of your diaphragm. In general the results of imaging tests such as PETCT scans are the most important when determining the stage of the lymphoma.

How do they stage lymphoma. In general the results of imaging tests such as PETCT scans are the most important when determining the stage of the lymphoma. When PETCT is available it is used for staging. PETCT scans combine CT and PET or positron emission tomography to find out how far the cancer has spread and how big it has become.

For other subtypes the disease has often spread throughout the body by the time it is diagnosed. The Ann Arbor System is the most widely used system for describing stages of non-Hodgkins lymphoma except in the case of Cutaneous T-Cell Lymphoma - Mycosis Fungoids - Sezary Syndrome which has a separate staging system. If either of the following is present it means the disease is stage I.
Lymphoma is called stage IIE if its in one organ and the nearby lymph nodes. It might also have spread to other nodes that are on the same side of your diaphragm. Stage III NHL is in lymph nodes.
Fight anxiety with knowledge. A diagnosis of stage 4 lymphoma might be difficult to accept. But its important to know that some types of stage 4 lymphoma may be curable.
Lymph nodes and what they do. Lymph vessels send lymph fluid through nodes throughout the body. Lymph nodes are small structures that work as filters for foreign substances such as cancer cells and infections.
They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid. Stage 4 lymphoma occurs when cancer has spread to a distant part of the body outside of the lymphatic system such as the spinal cord lungs or liver. They can provide a diagnosis using tests like blood panels biopsies and more.
You might also need additional tests to determine the stage of your lymphoma. Stage 1E lymphoma means that the lymphoma started in a single body organ outside the lymphatic system and is only in that organ. This is called extranodal lymphoma.
Stage 2 Stage 2. Two or more groups of lymph nodes affected all on the same side of the diaphragm either above or below. The stage is determined by.
The number and location of lymph nodes affected Whether the affected lymph nodes are above below or on both sides of the diaphragm the large dome-shaped muscle under the ribcage that separates the chest from the abdomen Whether the disease has spread to the bone marrow or to other organs such as the liver. Lymphomas are graded as low intermediate and high depending on the kind of lymphoma cells present and how they affect lymph nodes and chromosomes. Some lymphomas grow faster and require specific treatment.
Classifying them is complex because many kinds of lymphocyte cells can be involved. It is common for dogs with lymphoma to have lymph nodes 3-to-10 times their normal size. These swellings are not painful and feel like a firm.
