T-cell lymphoma is a type of non-Hodgkin's lymphoma, a type of cancer that affects the lymphatic system. It is usually diagnosed through a combination of physical examination, imaging tests, and laboratory tests.
Physical examination is typically the first step in the diagnosis of T-cell lymphoma. The doctor will examine the patient for swollen lymph nodes, lumps, enlarged organs, and other physical signs of the disease.
Imaging tests such as X-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI) scans are used to detect any abnormalities in the body. These scans can show if the lymph nodes, organs, and bones are enlarged or if any tumors are present.
Laboratory tests are also used to detect T-cell lymphoma. Blood tests can show if the patient has an elevated white blood cell count, which is usually present in people with this type of cancer. A bone marrow biopsy can also be done to determine if T-cell lymphoma is present.
Finally, a lymph node biopsy is often necessary to confirm the diagnosis. During the biopsy, a sample of tissue is taken from the lymph node and examined for the presence of cancerous cells.
Once the diagnosis of T-cell lymphoma is confirmed, the doctor will proceed with the appropriate treatment plan. Treatment typically includes chemotherapy, radiation therapy, and/or targeted therapy, depending on the stage and severity of the cancer.
