T-Cell Lymphoma: What Is It?
T-cell lymphoma is a type of non-Hodgkin lymphoma, a cancer of the lymphatic system. It is caused by a mutation of the T-cell, a type of white blood cell that helps fight infection. This mutation leads to abnormal and uncontrolled growth of the T-cell, which can lead to tumors in the lymph nodes, spleen, and other organs.
Where Does T-Cell Lymphoma Start?
T-cell lymphoma typically starts in the lymph nodes, which are small, bean-shaped organs located throughout the body. They filter out bacteria, viruses, and other harmful substances. When T-cell lymphoma develops, the cancer cells can spread to other parts of the body, including the liver, lungs, and bone marrow.
How Is T-Cell Lymphoma Diagnosed?
T-cell lymphoma is usually diagnosed through a biopsy. During a biopsy, a sample of tissue is taken and examined under a microscope by a pathologist. The pathologist will look for the presence of abnormal T-cells, which indicate T-cell lymphoma. Other tests, such as a complete blood count and imaging scans, may also be used to diagnose T-cell lymphoma.
