Did you know? 20% of Asian women over the age of 50 have osteoporosis and 52% have bone loss; compared to 7% of men with osteoporosis and 35% with bone loss. The incidence of osteoporotic fractures in women exceeds that of breast, ovarian and endometrial cancers combined. The vast majority of patients with osteoporosis go undetected and undiagnosed.
