Age: 60 years and over

Healthy Volunteers:

This study is NOT accepting healthy volunteers

Inclusion Criteria:

* • Histologically confirmed mantle cell lymphoma with cyclin D1 (BCL1) expression by immunohistochemical stains and/or evidence of CCND1 rearrangement or t(11;14)(q13;q32) as confirmed by the enrolling center (such as by fluorescence in situ hybridization \[FISH\], polymerase chain reaction \[PCR\]/sequencing, karyotype). Patients with cyclin D1 and/or t(11;14) negative mantle cell lymphoma with an expression profile suggesting a diagnosis of mantle cell lymphoma \[MCL\] such as SOX11 expression are also eligible * Any stage allowed (stage I-IV) * Patient must have at least one objective measurable disease parameter by PET or CT. Measurable disease in the liver is required if the liver is the only site of lymphoma OR bone marrow involvement by MCL * Steroids for management of mantle cell lymphoma are allowed up to a dose of prednisone 100mg/day (or equivalent) for up to 7 days prior to registration * No prior systemic treatment for mantle cell lymphoma * No prior radiation treatment for stage I MCL * No prior exposure to a BTK inhibitor or anti-CD20 monoclonal antibody * No prior stem cell transplant * Age \>= 70 years OR age \>= 60 to \< 70 years with comorbidities precluding autologous stem cell transplantation (autoSCT) including at least one of the following: a) cardiac ejection fraction (EF) \<= 45%, b) diffusing capacity for carbon monoxide \<= 60% predicted; c) creatinine clearance \< 70 but \>= 30ml/minute (min); d) Eastern Cooperative Oncology Group (ECOG) performance status of 2, which poses an unacceptable risk of toxicity for high-dose therapy and stem cell transplantation; or e) Cumulative Illness Rating Scales (CIRS) total score \> 6 * ECOG Performance Status 0-2 * Absolute neutrophil count (ANC) \>= 750/mm\^3 (without growth factor support within 7 days) * Platelet count \>= 75,000/mm\^3 (or \>= 50,000/mm\^3 if thrombocytopenia is due to lymphoma) without growth factor support or transfusion within 7 days * Creatinine clearance \>= 30 mL/ min determined by either: a) Estimation using the Cockcroft-Gault equation or b) Measurement by nuclear medicine scan or 24 hour urine collection * Total bilirubin =\< 1.5 x upper limit of normal (ULN) (unless documented Gilbert's syndrome) * Aspartate transferase (AST) / alanine transaminase (ALT) =\< 3 x ULN * Patients should not be considered candidates for stem cell transplant or must have declined a stem cell transplant strategy * No clinically significant cardiovascular disease including the following * Unstable angina within 3 months before registration * New York Heart Association class III or IV congestive heart failure * History of clinically significant arrhythmias (eg, sustained ventricular tachycardia, ventricular fibrillation, torsades de pointes) * Known QT correction formula (QTcF) \> 480 msecs based on Fredericia's formula (unless pacemaker in place) * History of Mobitz II second-degree or third-degree heart block without a permanent pacemaker in place * Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial * No active Hepatitis B or Hepatitis C infection. Patients with prior hepatitis B virus (HBV) exposure (positive HBV core antibody and/or surface antigen) are eligible if they have no detectable viral load, and are taking appropriate prophylactic antiviral therapy to prevent reactivation. Patients with history of hepatitis C virus (HCV) are eligible if they have an undetectable HCV viral load * Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial * No history of severe bleeding disorder such as hemophilia A, hemophilia B, von Willebrand disease, or history of spontaneous bleeding requiring blood transfusion or other medical intervention * No history of stroke or intracranial hemorrhage within 6 months prior to registration * No disease significantly affecting gastrointestinal function such as malabsorption syndrome, resection of the stomach or small bowel, bariatric surgery procedures, symptomatic inflammatory bowel disease, or partial or complete bowel obstruction. Patient must be able to swallow pills * Potential trial participants should have recovered from major surgery * No vaccination with a live vaccine within 35 days prior to registration * No hypersensitivity to zanubrutinib or rituximab or any of the other ingredients of the study drugs * Patients on strong CYP3A4 inhibitors must discontinue the drug for 14 days prior to registration on the study. * Patients on strong CYP3A4 inducers must discontinue the drug 14 days prior to registration.
