Teacher: Now, understand the problem? Solve this instance: Question: Is a prior diagnosis of breast cancer a risk factor for breast cancer in BRCA1 and BRCA2 carriers?
Answer: In a woman with a BRCA1 or BRCA2 mutation who is diagnosed with breast cancer, the risk of cancer in the contralateral breast depends on the first diagnosis. That observation supports the hypothesis that there are important genetic or non-genetic modifiers of cancer risk in BRCA carriers. Discovering risk modifiers might lead to greater personalization of risk assessment and management recommendations for BRCA-positive patients.
