It is easy to romanticise about escaping to the country, with its clean air, green space, and idyllic views. But our latest research, a review of 39 studies from around the world, suggests the need for a bit of an adjustment: it turns out that people living in rural locations are less likely to survive cancer.

We previously found that people in the northeast of Scotland who live more than an hour away from a cancer treatment centre are more likely to die within the first year after their diagnosis.

We were interested in whether studies from other parts of the world also found differences between urban and rural cancer survival. We also wanted to understand reasons why people living rurally might be disadvantaged.

We examined studies that observed people with cancer over time. The studies calculated the risk of a person dying from cancer depending on whether they lived in urban or rural locations. One of the things that can complicate research comparing urban and rural living is that pockets of poverty can exist geographically, and poverty negatively affects cancer survival. For this reason, we only included studies that accounted for deprivation levels.

The 39 relevant studies that we found were all from developed countries, mostly the US, Canada, the UK and Australia/New Zealand. They covered a large variety of different cancer types and involved more than two million people. Thirty of these studies found a clear survival disadvantage for rural people compared to their urban counterparts.

We wanted to find out exactly how much of a disadvantage rural patients had and we were able to aggregate the results of 11 of the studies. This led us to conclude that rural people are 5% less likely to survive cancer than those living in urban areas.

Understanding why

The authors of the original studies suggested reasons why people living rurally might do worse after a cancer diagnosis. It is possible that they behave differently to city dwellers. They might be more likely to smoke or consume more alcohol, for example. It is also possible that rural people are more stoical, and might put off seeking help for symptoms.

Access to services is also likely to be important. Most developed countries centralise their specialist cancer services within major cities, and this could potentially lead to disadvantages for rural people.

Some studies suggest that patients who live far away from specialist centres might be treated differently – not receiving radiotherapy, for example. Travel burden, transport infrastructure, and the way that cancer services are organised are important considerations. It might be, for example, that people in rural areas are more likely to avoid long journeys to city hospitals for treatments that will only make small improvements to their life expectancy.

Whatever the case, more research is needed to determine exactly which factors are at play, and which are the most important. Equally, it raises questions about survival rates for other illnesses in people living in the countryside.

There are many advantages to living in rural areas, and we are certainly not suggesting that everyone should move to the city. The big question is what we could do to improve cancer outcomes in people who live far away from cancer centres. Recognising that there is a problem is a good starting point, and research to build a deeper understanding of the problem could be coupled with innovative strategies to reduce rural cancer inequality.

One area of promise is digital/communications technology, such as getting people to communicate with clinicians via the internet. Possibilities would include everything from more automated appointment reminders to apps that help people to examine themselves online. On the whole, however, we need to better understand the problem better before we start proposing solutions. Having established that there is a definite disadvantage to living in the countryside if you have cancer, we now need to get to the bottom of it.The Conversation

Editorial Review:

In her New York Times bestseller, Radical Remission: Surviving Cancer Against All Odds, Dr. Kelly A. Turner, founder of the Radical Remission Project, uncovers nine factors that can lead to a spontaneous remission from cancer—even after conventional medicine has failed.

While getting her Ph.D. at the University of California, Berkley, Dr. Turner, a researcher, lecturer, and counselor in integrative oncology, was shocked to discover that no one was studying episodes of radical (or unexpected) remission—when people recover against all odds without the help of conventional medicine, or after conventional medicine has failed. She was so fascinated by this kind of remission that she embarked on a ten month trip around the world, traveling to ten different countries to interview fifty holistic healers and twenty radical remission cancer survivors about their healing practices and techniques. Her research continued by interviewing over 100 Radical Remission survivors and studying over 1000 of these cases. Her evidence presents nine common themes that she believes may help even terminal patients turn their lives around.

Editorial Review: Now updated and revised, the definitive book on surviving prostate cancer from the world's leading authority on the prostate.

Each year, more than 230,000 men are diagnosed with prostate cancer, and 30-40% of patients who are diagnosed will eventually relapse. But the good news is that more men are being cured of this disease than ever before.

Now in a revised fourth edition, this lifesaving guide by Dr. Patrick Walsh and award-winning science writer Janet Farrar Worthington offers a message of hope to every man facing this illness. Prostate cancer is a different disease in every man--which means that the right treatment varies for each person. Public awareness for this disease has transformed treatment and opened up new avenues of research; rapid advances in knowledge are being translated in new recommendations for management. In this book, Dr. Walsh will address questions such as:
  • What causes prostate cancer? Your risk factors, including heredity, diet, and environment.
  • Can I prevent prostate cancer? How some simple changes in your diet and lifestyle can help prevent or delay the disease.
  • Does prostate cancer need to be treated at all? This hot-button issue is vital for men to understand.
  • How do I know if I have prostate cancer? An explanation of the recently refined and expanded recommendations.
  • How can my prostate cancer be treated? The pros and cons of new technologies and new information on focal therapy.

Editorial Review: Surviving Cancer offers hope and a strategy for anyone who has been diagnosed with a solitary tumor.



In reading these pages, you will learn that the body can continue living while accommodating a solitary cancer. There are actions you can take that may prevent it from spreading, even if there are complications.



Surviving Cancer explains how you can change your diet and lifestyle habits to survive cancer -- to keep it from metastasizing and spreading to other organs in your body. Most of all, it will explain how you can literally starve cancer cells... forcing them to disappear or die.



The main focus of this book will teach you that diet is perhaps the key factor in defeating cancer, especially avoiding grains. Grains create enormous amounts of glucose in your bloodstream--and cancer cells thrive on glucose to survive and multiply. High blood sugar levels also encourage the body to release insulin, and again, this is a great danger to your cancer. Insulin promotes cell growth, including cancer cells.



The book provides insightful information on the causes of cancer, how it forms, how it may spread, and what you can do to control the cancer and return to a healthy life. The chapters also contain specific advice on avoiding exposure to environmental toxins; the value of sleep, exercise, and stress reduction; the use of spices in cooking; building good bacteria in your gut; and many other factors you con control that may help prevent a cancer from spreading to other parts of the body.



This book is for anyone who has cancer localized to a single site and not yet colonized in another part of the body. It is also for anyone who believes they are at risk of cancer due to heredity, lifestyle, working conditions, or for any other reason.



Surviving Cancer is also especially important for anyone with Type 2 diabetes, with or without cancer, to learn about the link between the two.If you have diabetes, this is an important cautionary book to read to prevent yourself from developing cancer.
