  • To understand a diagnosis of mantle cell lymphoma, it is helpful to briefly consider where in the body it develops. (moffitt.org)
  • Mantle cell lymphoma develops in the B lymphocytes. (moffitt.org)

  • As with other forms of cancer, lymphoma is a malignancy caused by abnormal cell growth. (moffitt.org)
  • In the case of mantle cell lymphoma, the cancer starts in the outer edge of a lymph node follicle, an area known as the mantle zone. (moffitt.org)
  • What are the common symptoms of mantle cell lymphoma? (moffitt.org)
  • Many people with mantle cell lymphoma have no symptoms during the early stages of the disease. (moffitt.org)
  • When symptoms begin, they are often similar to those caused by a wide variety of other health conditions, which makes mantle cell lymphoma somewhat challenging to diagnose. (moffitt.org)
  • Perhaps the most telling sign of mantle cell lymphoma is the persistent, painless swelling of lymph nodes in the neck and throat areas. (moffitt.org)
  • What causes mantle cell lymphoma? (moffitt.org)
  • How is mantle cell lymphoma diagnosed? (moffitt.org)
  • If a diagnosis of mantle cell lymphoma is confirmed, the doctor will determine what stage the cancer is in. (moffitt.org)
  • Because patients with this type of lymphoma often display no symptoms or have symptoms that are similar to those of other health conditions, mantle cell lymphoma is often diagnosed in its late stages. (moffitt.org)
  • How is mantle cell lymphoma treated? (moffitt.org)
  • For patients who are diagnosed with a less aggressive form of mantle cell lymphoma, physicians may recommend a short period of "watchful waiting"-or monitoring the cancer progression before starting active treatment. (moffitt.org)
