Question

Quizplus · Accepted Answer

The majority of women diagnosed with breast cancer do not have an inherited genetic risk. Only a small percentage of breast cancers (5-10%) are caused by inherited genetic mutations, such as BRCA1 and BRCA2. The majority of breast cancer cases are sporadic, meaning they occur due to a combination of environmental and lifestyle factors, as well as random genetic mutations.
