The lymphatic system is part of the immune system which defends the body against infection. A clear fluid called lymph flows through the lymph vessels and it contains white blood cells called lymphocytes. Lymphoma is a general name for cancer of the tissue of the lymphatic system where there is a large number of abnormal clones of lymphocytes causing swelling of lymph nodes or involvement of other organs. This can disrupt the immune system and reduce a person’s ability to fight infections. The lymph nodes can also become swollen, forming painless lumps or tumours.

• Past diagnosis of certain severe viral infections that suppress your immune system.
  • For example, the Human Immunodeficiency Virus (HIV) and the Epstein-Barr Virus (EBV).
  • A suppressed or weakened immune system can lead to a higher risk.
• Patients with organ transplants and on immuno suppressive drugs.
  • A suppressed or weakened immune system can lead to a higher risk.
• A history of cancer and prior cancer treatment with chemotherapy or radiation therapy.
• Frequent exposure to radiation or chemicals such as:
  • Pesticides
  • Solvents
  • Fertilisers
• A family history of lymphoma.

• Painless and enlarged swelling of the lymph nodes in the neck, armpit, groin or abdomen.
• Unexplained fevers.
• Drenching night sweats even in cool weather.
• Unexplained weight loss.
• Patchy red skin and itching without an obvious cause.

Most lymphoma patients do not have any known risk factors. The symptoms may be caused by a number of other unrelated medical problems and may not indicate the presence of cancer, but if any of the above symptoms persists or is bothering you, do consult your doctor.
