Hi Danielle, sounds like I have the same treatment as you, although I also had axillary dissection as the initial biopsy found lymph node involvement. I just had my first chemo treatment last Monday...so far, so good: the steroids and anti-nausea meds and I worked for a few hours yesterday, first day back since surgery 5 weeks ago. FYI I am still a little tender and swollen from the surgery.
For what it is worth....
Even though I developed mastitis in the breast I had the lumpectomy within 24 hours of having the first treatment (opportunistic infection) I am not concerned about the side effects of the chemo killing me....I had a training session on how to look after myself, they coach you at the treatment, they give you contacts to call if you have any symptoms, they give you letters to take to work about what you can and can't do...I know I am likely to get sick at some point in the six months, maybe very sick but I do have faith that the team caring for me know how to get me through it. I am clinging to the hope I will be one of the lucky ones who don't get sick, and taking all precautions but realistically I understand that I am putting my body through a lot.
Hope this helps you think hunk about your own situation, all the best x
