🔸 Introduction: Mantle cell lymphoma affects the blood and understanding it can aid in symptom management and treatment.

🔸 What is MCL?: Often termed MSL, it’s a form of non-Hodgkin lymphoma in white blood cells. Around 70 non-Hodgkin lymphomas exist, with MSL identified as such by WHO in 1992.

🔸 Prevalence: MCL accounts for roughly 6% of all non-Hodgkin lymphoma cases. Annually, about 4,200 people are diagnosed with MCL in the U.S., making it relatively rare.

🔸 Causes: The exact cause remains unidentified, but mutations in the B lymphocyte or B cell might play a role, causing them to produce excessive protein and lead to lymphoma.
