Authors' conclusion

Compared with those of matched controls, the incidence of osteoporotic fractures among lymphoma patients within 18 months after lymphoma diagnosis was significantly greater. The risk was especially increased in the 51-60-year age group.

Major osteoporotic fracture (MOF) and hip fracture risk · 15 years postdiagnosis

Risk among lymphoma patients nearly equivalent to that of the general population
