HER2+ and need some buddies

Hi, all, well I’ve had my MRI, results probably about 2 weeks, had oncology appointment! I’m having docetaxel, carboplatin and phesgo, once every 3 weeks for 6 cycles. Waiting for start date now, i can have picc line or canula, what are opinions please? Also considering cold cap but not sure if it might be too much to cope with. X
