<s>[INST] I have completed my Radiation therapy for 35 days and for chemo cistapline for Cancer LA on 7 April 2010.  My Oncologists say that total effect of cure can be known after 2/3 months and has suggested me for a visit on 28 May 2010.  What do you say ? [/INST] Hello dear. The effect of treatment can be said only after 8 to 12 weeks of the treatment as in between this period radiation effect persist and can lead to false results. So do not worry and get evaluated after a gap of 2 to 3 months. Hope you understand. Take care </s>
