There should be serious research and studies on the effectiveness of chemotherapy. Now there are few voices against it but it is not enough to reject it. Chemo have to develop further to increase its accuracy. Most of the solutions in modern medicine is evolved by years by increasing the effect and decreasing the adverse. Like that chemo will also evolve. It is foolishness to say that all chemo treatment is bad. I am an Ayurveda Doctor, but still i support chemo for later stages of cancer. There is no other assured solutions even though chemo is risky.
Also there should be serious study on the society about the causes of cancer and why it is rapidly increasing among us. We do not know whether is a side effect of something which we adapted in recent era. It can be any food, medicine or other. There should be advanced statistical analysis. There were cancer cases from ancient times, but they are not this much wide spread.
