Hi @CarrieP,
Sorry to hear you are feeling anxious.
Chemo side effects vary from person to person. Ive just finished Ac and taxol. I think after the first chemo it tends not to be very dramatic.
Dont worry if you arent having nail changes or hair is not falling. Your hair will probably fall out but it is individual. You will think nothing is really happening then all of a sudden movement.
I think at about my second taxol i asked the oncologist how he knew it was working and he said it would be in the months and years to come. I found this very unsatisfactory as an answer but id already had surgery and i had yet to understand that the drugs are really given as a program which they figure will do the required job. In my case apart from blood results presumably to check how my body was coping there were no tests throughout chemo. The programs are given based on your scenario and what they know will best hit the cancer cells. Hope that kindof helps. Try not to worry. Some people dont get many side effects others like me get plenty. I hope you are one who gets few. Regardless it is manageable.
In terms of the biopsy, it sounds lije they traumatised the area a little. Try not to worry but if it doesnt get better go to your gp or whoever is looking after you and have them look. No query is silly and it will allay your fears.
Sending you hugs
Michele
