Professor Karol Sikora, one of the world's leading cancer experts - an oncologist for 44 years and a past director of the WHO Cancer Programme - talks about his experience of treating cancer over the last four decades, and  explains what cancer patients really need to know. He believes those who take an active interest in their care are in the strongest position to get the best treatment, so knowing how to navigate the health care system effectively can make a huge difference.
He talks about his experience in the UK's NHS, but much of his advice will be useful to patients in many other countries too.
