![]() The outlook for cancer that has spread to lymph nodes will depend on the type of cancer.įor example, the American Cancer Society (ACS) defines the 5-year relative survival rate as follows for cancer that has regionally advanced, including spread to the nearby lymph nodes:Ī relative survival rate helps people understand what chance a person has of living of a certain number of years after receiving a diagnosis compared with those without the condition. This number provides additional information:Ĭancer cells in the lymph nodes usually indicate that cancer is spreading. When a doctor uses the TNM system, they will place a number after each letter. M refers to whether cancer has metastasized (spread).N refers to the number of nearby lymph nodes that have cancer cells.T refers to the size of the original tumor.In the TNM system, each letter refers to a different feature of the cancer: For some cancers, lymph node involvement occurs at stage 2, but in others it can mean cancer has reached stage 3.Īnother way of staging cancer is the TNM staging system. The staging will depend on the type of cancer. Healthcare professionals also break stages into further subcategories, using a, b, and c. Stave 4 is when cancer has spread to areas that are distant from the original tumor.The higher the stage, the larger and more extensive the cancer is. Stage 1, 2, and 3 indicate that cancer is present.Stage 0, or carcinoma in situ (CIS), is when abnormal cells are present but have not spread.There are different ways of staging cancer, for example: The stages of cancer indicate how far cancer has traveled from its original location. Research indicates that osteosarcomas, a form of bone cancer, only involve the lymph nodes in 4–11% of cases. Some spread quickly to the lymph nodes, while others develop and spread more slowly. ![]() The rate that cancer spreads to a person’s lymph nodes may depend on the type of cancer. When does cancer spread to the lymph nodes?
