2002

Abstract Background : Nonpuerperal mastitis may mimic breast cancer but the incidence of noninflammatory cancer among such patients is unknown. Aim : To estimate the risk of breast cancer in patients with nonpuerperal mastitis within 12 months of treatment. Study design : Two hundred seventy-seven patients with nonpuerperal breast inflammation were prospectively screened for breast cancer within 1 year after mastitis was diagnosed. The age-related standardized breast cancer incidence ratio of the female population was calculated. Results : Five women (35, 43, 47, 61, and 72 years, respectively) were identified as having noninflammatory breast cancer independently, and at a location distant …
