synchronous breast cancer
Synchronous breast cancers are two (or more) primary breast cancers that occur in either breast at the same time.
Epidemiology
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.
Radiographic features
Breast MRI
With MRI screening, there may be a 4-10% rate of contralateral breast cancers when a unilateral breast cancer is found .
Treatment and prognosis
The survival of women with synchronous breast cancers is worse than those with unilateral disease .
Differential diagnosis
Considerations include:
- metastasis to the breast from the opposite breast: unusual particularly if there is no other evidence of metastasis
