What is a common symptom of Non-Hodgkin lymphoma?

Swollen lymph nodes are a common symptom of Non-Hodgkin lymphoma due to the nature of the disease, which originates in the lymphatic system. The lymphatic system is an integral part of the immune system and is made up of lymph nodes, vessels, and organs. In Non-Hodgkin lymphoma, malignant lymphocytes proliferate, causing lymphoid tissues to swell and the affected lymph nodes to become enlarged and palpable. This swelling can occur in various areas, including the neck, armpits, or groin, often without pain.

This symptom is critical as it signals that something is amiss within the immune system. Early detection of these swollen lymph nodes is vital for diagnosis, leading to appropriate medical intervention. Other symptoms of Non-Hodgkin lymphoma may include fever, night sweats, and unexplained weight loss, but swollen lymph nodes are often the most visible and identifiable sign of the disease during physical examinations.
