People have an undying love for coffee. Around the world, it’s estimated that 2 billion cups are drank every single day. Lots of people can’t start the morning without one, and there’s now a coffee shop on every corner in every city.
Last year Cancer Research UK launched the latest campaign aimed at reducing obesity related cancers. This is an important issue, with obesity now being recognised as the second biggest preventable cause of cancer, behind only smoking. The evidence for this is extremely solid, and it is expected to cause an additional 15,000 deaths in the UK from cancer this year alone. And the numbers are increasing steadily. In the 20 years from 1993 to 2013, the number of people classed as overweight or obese in the UK increased by 6 million.
There are many scam artists around nowadays proclaiming the benefits of their particular unproven stem cell therapy, for anything from curing cancer to making paralysed people walk again. It’s not surprising really; stem cells are a pool of cells in every organ that are almost eternally youthful and can regenerate themselves and all other cells in the organ. They sound almost magical. However, last year the FDA (the US Food and Drug Administration) had to move to crack down on these clinics, citing the of lack of evidence that any of them work and a number of serious complications reported following treatment. Complications including patients in Florida dying, a woman developing bone fragments in eyelids following a stem cell facelift, and another developing nasal tissue in her spine after a doctor promised to cure her paralysis with stem cells.
It is a field ripe for abuse partly because it is one with so much potential. Stem cells do have fascinating possible applications, and there is a lot of research going in to them at the moment. Unfortunately, most exposure people have with them is in science fiction or alternative medicine. Which is why it was very interesting to see a study published last week that underlined how much real potential this field of research has. The study used mice instead of humans, so is still at an early stage, but is very promising nonetheless. Continue reading
You may have seen a frankly terrifying headline this week:
“Hot drinks probably cause cancer, warns World Health Organisation”
Telegraph, 15th June 2016
Almost every news source carried this story, and the headlines were universally similar to the one above. This story comes from a report by the WHO, which looked at the association between coffee and mate (a South American herbal tea) and various forms of cancer. In short, they found that there was no association between coffee or mate and cancer, but that the temperature of the beverage may be linked to oesophageal cancer. Continue reading
A few months ago I wrote here about the rise of e-cigarettes. In that post I pointed out that e-cigarettes are far less harmful than tobacco, and should be marketed as a safer alternative to smoking. There has been an interesting update on this topic today, with the Royal College of Physicians (RCP) recommending that all smokers be offered and encouraged to use e-cigarettes. Continue reading
It’s a simple fact that the most effective thing we can do to cure more cancers is to catch them earlier. If we find bladder cancer at an early stage, the five year survival is 88%; if we catch it at a late stage, when it has started spreading around the body, it drops below 15%. This is why we screen for certain diseases, including breast, bowel and cervical cancer. These large-scale screening programs are the best hope we have for majorly reducing the toll cancer takes on our lives. Continue reading
I’ve seen this story pop up on my newsfeed a few times recently, so I thought I’d have a look and see if there is much to it.
It is an article about some new guidelines in Sweden regarding arsenic in rice products. They state that due to high levels of arsenic, some rice products can be harmful to children, and that many of them should be rationed, or even avoided altogether.
In case you don’t want to read the rest of this blog post, I’ll give you my take on it first. Continue reading
