Alternative medicine and cancer survival (Part 2)

My last blog post was about alternative medicine in cancer treatment. That piece was about patients who refuse all other treatment, and thankfully that is still a relatively rare occurrence. Usually, patients use alternative medicine alongside their regular treatment. As a result, studying patients who refuse all regular treatment isn’t necessarily the most informative thing.

Because of this distinction, researchers from Yale decided to have a look at patients who do this, and they published their results this month. It is not encouraging reading. Continue reading

Alternative medicine and cancer survival

I often wonder just how much I annoy people when the topic of alternative medicine (alt med) comes up. In general, if someone says something I don’t agree with, I let it slide. When it comes to alt med, however, I don’t seem to have the same restraint. It’s unfortunate really, as it comes up surprisingly often, and my position comes across as pretty extreme.

People ask “What’s the harm?”, and point out that “Even if it doesn’t do anything, people feel better having tried it”. I empathise with this position, but completely disagree. The point I try to make is that if we accept the use of alt med, we legitimize it, making people more likely to choose it over conventional medicine.

Alt med banner smaller

The focus of this post is cancer patients who put all their trust in alt med. While it’s true that most people use alt med alongside real medicine, the popularity of, and belief in, the alt med movement means that it is inevitable that some people will ignore mainstream medicine in favour of alternatives.

Unfortunately this does happen, and it happens regularly enough for us to study it. A few months ago, researchers from Yale published a paper looking into the outcomes for cancer patients who chose alt med over conventional treatment.

Disparities in cancer survival

In my last post I published some good news about cancer survival rates, so I thought it was important to highlight a big problem with our recent success against this disease. This issue is flagged up in a study published at the end of January.

It addresses the fact that the gains we have made in cancer diagnosis and treatment are very unevenly spread around the world. To analyze this is greater detail, the scientists studied the differences in survival in different countries, and the results are somewhat predictable.

If, for example, you are an Australian or American with breast cancer, you have a 90% chance of surviving. If you are Indian however, you only have a 66% chance.

Are cancer rates rising?

Cancer is so prevalent in life now that it is easy to think that the rates are skyrocketing. However, the numbers don’t back this up. In actual fact, we are slowly but surely advancing our response to the disease, and recently published data underlines this progress.

The publication was the annual report of the American Cancer Society. In that article, they compile all the recent data to see what trends there are in cancer rates and deaths.

The report delivers some good news.

Ultra-processed foods and cancer

This story was all over the news today:

“Ultra-processed foods may be linked to cancer, says study”

The Guardian, 15th Feb. 2018

The news comes from a French study that looked into whether cancer was associated with highly processed foods. As usual, the question is whether the actual results of the study warrant the hysteria currently playing out in the media? (Spoiler: the answer to that is almost always an emphatic NO!)

Anti-obesity campaigning and stigmatization

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.

Eggs, cancer, and motivated reasoning

The following headline in the The Daily Express caught my attention this week:

“Ovarian cancer – could EGGS be the cause of disease? Vegan charity research REVEALED”

Express.co.uk 14th March 2017

The article goes on to explain that a Bristol based charity called Viva! Health has urged consumers not to eat eggs, claiming that one egg a week increases cancer risk by up to 70%. According to their own website, Viva! Health is a science-based health and nutrition charity, and being “science-based” you would expect them to have sufficient evidence to make a claim as eye-catching as the one above. So is this the case?food-eggs
