Adult Non-Hodgkin Lymphoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Adult Non-Hodgkin Lymphoma
For pregnant women with non-Hodgkin lymphoma, staging tests that protect the fetus from the harms of radiation are used. These include MRI, bone marrow aspiration and biopsy, lumbar puncture, and ultrasound, which do not use radiation. An ultrasound exam is a procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram.
There are three ways that cancer spreads in the body.
The three ways that cancer spreads in the body are:
- Through tissue. Cancer invades the surrounding normal tissue.
- Through the lymph system. Cancer invades the lymph system and travels through the lymph vessels to other places in the body.
- Through the blood. Cancer invades the veins and capillaries and travels through the blood to other places in the body.
When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer.
Stages of adult non-Hodgkin lymphoma may include E and S.
Adult non-Hodgkin lymphoma may be described as follows:
- E: "E" stands for extranodal and means the cancer is found in an area or organ other than the lymph nodes or has spread to tissues beyond, but near, the major lymphatic areas.
- S: "S" stands for spleen and means the cancer is found in the spleen.
The following stages are used for adult non-Hodgkin lymphoma:
Stage I adult non-Hodgkin lymphoma. Cancer is found in one lymphatic area (lymph nodes, tonsils, thymus, or spleen). In stage IE (not shown), cancer is found in one organ or area outside the lymph nodes.
Stage I adult non-Hodgkin lymphoma is divided into stage I and stage IE.
- Stage I: Cancer is found in one lymphatic area (lymph node group, tonsils and nearby tissue, thymus, or spleen).
- Stage IE: Cancer is found in one organ or area outside the lymph nodes.
Stage II adult non-Hodgkin lymphoma is divided into stage II and stage IIE.
Stage II adult non-Hodgkin lymphoma. Cancer is found in two or more lymph node groups, and both are either above (a) or below (b) the diaphragm. Stage II: Cancer is found in two or more lymph node groups either above or below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen).
Stage IIE adult non-Hodgkin lymphoma. Cancer is found in one or more lymph node groups either above or below the diaphragm and outside the lymph nodes in an organ or area on the same side of the diaphragm as the lymph nodes with cancer (a). Stage IIE: Cancer is found in one or more lymph node groups either above or below the diaphragm. Cancer is also found outside the lymph nodes in one organ or area on the same side of the diaphragm as the affected lymph nodes.
