Sir, Chemo Radiation of Capacitabine tablets and Proton Radiation is finished at Apollo Proton Care, Velachery Chennai for Neuro Endocrine Tumour (Colon Rectal Cancer) Now Chemo has to start. She has been asked to wait for 3 weeks for radition effect (soft skin) to go. My query is what will happen now - with no radiation or capacitabine tablets. Will cancer cells grow or continue to die or remain at a level. Her CEA has fallen from 26 to 13.
