New info on genes?

At the beginning of the year I did genetic testing and all was negative. Today I see in my chart this new info: BRCA negative PIK3CA positive, T p53 positive, MSI stable. AK T1, BRAF, ER B B2, ESR 1, PTEN negative I know my doc was waiting in the cTDNA testing results (Personalis test). Is this what that is from? T p53 was noted as negative from my earlier genetic testing, so I’m a little confused. Don’t know if I should be extra worried here, or just my normal amount of worry 😂. I am sure she will go over all of this when I see her, just wanted to see if anyone could explain to me in the interim.
