Ok. Its good you had the complete genetic panel.
Yes, have faith. Some are a bit resistant to taxanes, but the FEC / AC can do a lot of damage.
Just drink a ton of water, rest well, and believe. It's going to be fine.
Being scared is normal. But, you are getting more chemo and you have a fine medical establishment looking after you. TNBC is a hot research area and all you can do is believe and hit this hard with your current line of AC treatment. It's going to work and its going to melt. In the mean time, smile a ton, enjoy the day to day, rest well, and eat well while you can.
You're going to be fine. We are all together here. We are well-wishers. You're not alone. We all went through the same and are going through the same on a day to day basis.
good luck with the AC. Make sure you drink lots of water daily.
