Results
- There were a total of 1,167,783 screening episodes across Scotland over the 7 year study period. 3797 screening episodes had breast implants in situ (0.3%).
- 21 women with augmentation were diagnosed with breast cancer, giving a rate of 5.5 per 1000. This is significantly lower compared to the breast cancer detection rate for general population in Scotland (8.4 per 1000) , (p<.05).
- 18 out of 21 breast cancer women had standard and additional implant displacement views.
- 18 cancers were identified on standard views. 2 lesions were more obvious on the push back views. One occult lesion was not seen either standard or push back views.
- The breast cancer lesions presented in the form of focal mass (71%) or microcalcification (19 %); the size ranged from 4mm to 60mm.
- 6 types of breast cancers were detected among 21 patients (see table). 13 were invasive and 5 had nodal spread at the time of diagnosis.
