Final answer:
The prognosis for indolent lymphoma is fair, with many patients living many months to years untreated. Regular monitoring is necessary to determine if treatment is needed.
Step-by-step explanation:
The prognosis for indolent lymphoma, also known as low-grade or slow-growing lymphoma, is generally fair with many patients living many months to years untreated. Unlike aggressive lymphomas, indolent lymphomas tend to progress slowly and may not require immediate treatment. However, the disease may eventually transform into a more aggressive form, and treatment should be considered at that point. Regular monitoring by healthcare professionals is crucial to ensure timely intervention if necessary.
