Difference between a reoccurrence & secondary TNBC

Hi can someone tell what the difference is as my sister has just been diagnosed with a reoccurrence of TNBC which is incurable and has been told her next chemo will be indefinitely on going- I’m sorry I am so ignorant but I am trying my best to Understand what she is going through, hopefully some of you ladies can help. Her reoccurrence is with her chest wall in the nodes under her arm in the nodes. Is this mets?
Hoping for a reply xo
