Dear Dr Sumeet, My mother has been diagnosed with Right CA Breast since last Oct, 2013 and has under gone Mastectomy with Chemo Therapy of CEF X 3 completed on 13.12.2013 and SA Docetaxel X 3 completed on 19.02.2014 along with Herceptin for One Year started on 03.01.2014. She has already completed the 15th dose of Herceptin and the 16th and 17 th dose will be administered in November & December 2014. Our Oncologist is now saying that the doses of Herceptin will not be required post December and the Chemo therapy will be over in December, 2014. However, What I learn from Internet that at least 18 dosage of Herceptin is required and further the last dose (17th Dose) is stated to be on 17.12.2014, whereas the One year is to expire on 03.01.2015. Since the said medicine is given at the interval of 21 days the 18 th dose if allowed will be on 07.01.2015. Is it Okay to have the medicine till 17 th dose or the Oncologist may kindly be requested for the last dose on 07.01.2015. Please Suggest.
