For ladies aged fifty in order to 64 years that have heterogeneously otherwise most dense bust, the fresh new RR try step 1.29, and people aged 65 so you can 74 age, it is 1.31. 7 But not, lady which have heavy breasts which establish breast cancer don’t possess a greater chance to possess passing away about disease, shortly after modifications getting phase, procedures, particular identification, and other chance circumstances, according to studies about BCSC. fifteen
