Screen-detected mucinous breast carcinoma: Potential for delayed diagnosis

Although mammographically benign appearances of mucinous carcinoma caused a delay in diagnosis in 38% of the present cases, mucinous breast carcinomas have a favourable prognosis, as they are often low-grade tumours and rarely metastasize. Delay in diagnosis for these tumours in a screening programme may not lead to a significant adverse outcome for most women.
