This blog post is a follow on from this post I wrote about cancer survival, and is about some really interesting quirks we encounter when we try to study it. These problems arise when we increase our ability to detect the cancer at earlier stages. Continue reading
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.
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.
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!)

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.
