Tomorrow, I will be getting my biopsy results but am curious both my older sister and I are CHEK 2 positive and my sister is currently Stage 4, I found out that she is boHer2 positive and Her2 negative. How common is it with someone who has the same genetic mutation to be diagnosed with the same type of cancer ? I probably wrote it incorrectly just learning a lot of new stuff lately
