Jose….I understand your concern and hesitation, but you must know that people do respond favorably to chemotherapy. Why not your sister also? You have been a wonderful, supportive, brother to her all along therefore, continue to support her with her decision and think positive thoughts.
Intermittent scans and blood tests results will provide a fairly clear picture of response to treatment. Often time’s scans will be ordered following the 6th consecutive chemo dose although, at times and for various reasons, the physician may order scans after the 4th dose.
Either way, I am expecting to hear good news soon.
Hugs,
Marion
