There is opinion saying Radiotherapy and Chemotherapy treatment are not actually killing the cancer cells but the cells are kept [or maybe deactivated] for a period of time... It will strike back. At that point of time, we may be able to do the same treatment/s, but the attack usually more severe than the first. Possibly, the patient may have no energy to go through the second episode of treatment (due to age and/or tiredness and/or cost incurred). If you are not lucky, the second cancer will strike due to the treatment itself. So, instead of killing the cancer cells the treatment may create second cancer. Appreciate comments please
