If you want what I consider to be an honest appraisal of the ongoing cancer situation just take a look at the news pages on the UK's cancer research website.
An individual now has a much greater chance of surviving cancer than they did, say, 30 years ago, and that is a fact.
There's a lot of tosh spouted about, particularly on the internet about radiotherapy and chemotherapy being bad things and that a changed diet and/or turmeric, bananas, broccoli will cure cancer. Oh yeah? Just try it and you'll probably end up deceased.
Likewise lots of people have this idea that the large pharmaceutical companies suppress certain drugs that will cure cancer just to make profits which I believe to be complete rubbish. Your biggest enemy in this field is the government.
Remember - they (The NHS) cured me of cancer - twice. And I am not a remarkable human being, just Joe Average so I figure I'm living proof nobody is out to get you.
Mind you, the energy alternatives? I'm not so sure about that, all the time oil makes a few individuals rich I do think it's likely we won't see that many alternative energy sources emerge.
