Dal, you have joined a great site. There is lots of support on here from people who know what you are going through. Some may have had the same chemo but we all seem to get different side effects. I myself, had 4 rounds of TAC chemo and two of AC. I too had a large tumour which was 9 cm. Took up my whole breast practically. The first lot of chemo shattered the tumour into pieces which made it easier for the surgeon to remove. Unfortunately for me I developed lung problems from the TAC and that is why it was changed to AC. I managed to get through it all by taking one day at a time. I set myself goals. Firstly to get through chemo, secondly to get over my mastectomy and thirdly, radiation. I did it and so will you. Any queries you may have, however small you think they may be, ask on here. Someone will give you a guiding hand. I wish you well in your treatment.
big hugs to you,
Linda xx
