Synchronous breast cancer

Dr Henry Knipe and Radswiki et al.

Synchronous breast cancers are two breast cancers that occur in either breast at the same time. 

Up to 10% of all breast cancers may be synchronous (particularly found with the use of breast MRI). The occurrence of bilaterality is greatest with invasive lobular carcinoma.

With MRI screening, there may be a 4-10% rate of contralateral breast cancers when a unilateral breast cancer is found 1.

The survival of women with synchronous breast cancers is worse than those with unilateral disease 3.
