Question: How close are you to finding a cancer cure?

From the viewpoint of a physicist, using beams of accelerated protons or heavier ions such as carbon, oncologists can deliver cell-killing energy to precisely targeted tumours without causing extensive damage to surrounding healthy tissue, eliminating the major drawback of conventional radiation therapy using x-rays. It could cure a very high percentage of tumors if we could give sufficiently high doses of radiation, which still needs a lot of research. As for curing all kinds of cancer, I think it still has a long way to go.
