Non-Hodgkin Lymphoma
1 medicine
Non-Hodgkin lymphoma is a group of more than 60 blood cancers that start in the lymphatic system, ranging from slow-growing subtypes managed by monitoring to aggressive forms treated with prompt chemotherapy.
Key facts
- Non-Hodgkin lymphoma (NHL) is an umbrella term for more than 60 types of cancer that start in lymphocytes, the white blood cells of the lymphatic system.
- Subtypes vary enormously: some grow slowly (indolent) and may only need monitoring, while others are aggressive and need prompt chemotherapy.
- Treatment is chosen by subtype and stage, ranging from a single alkylating agent like chlorambucil to combination regimens under specialist oncology care.
- Enlarged lymph nodes, unexplained weight loss, night sweats, or persistent fatigue warrant prompt specialist assessment.
What non-Hodgkin lymphoma is
Non-Hodgkin lymphoma is not a single disease. It is a group of more than 60 related cancers that arise from lymphocytes and, unlike Hodgkin lymphoma, share no single defining cell marker. That diversity means subtypes differ widely in how fast they grow, how they spread, and how they respond to treatment, so confirming the exact subtype and stage always comes before a treatment plan is set.
Symptoms to watch for
The classic warning signs are painlessly enlarged lymph nodes in the neck, armpit, or groin, alongside unexplained weight loss, drenching night sweats, and persistent fatigue. These symptoms overlap with many less serious conditions, but their combination, or their persistence over more than a couple of weeks, should prompt a specialist assessment rather than a wait-and-see approach.
How NHL is treated
Treatment depends heavily on subtype, stage, and how quickly the cancer is growing. Slow-growing (indolent) lymphomas are sometimes monitored without immediate treatment, since early intervention does not always improve outcomes in this group. Aggressive subtypes usually call for prompt chemotherapy. Alkylating agents such as chlorambucil have a long track record in indolent disease, particularly for older or frail patients where tolerability is a priority. More complex cases are managed under specialist oncology protocols that combine multiple agents with supportive care.
When to see a doctor
Seek specialist assessment as soon as enlarged lymph nodes, unexplained weight loss, drenching night sweats, or persistent fatigue arise. Earlier diagnosis generally means more treatment options and a better chance of durable remission.
