If you were to be diagnosed with cancer, how do you think you would feel? It would depend on the type of cancer of course, but there’s a good chance that no matter the details, the word “cancer” would make the diagnosis much more frightening. Frightening enough, in fact, to do you as much harm, or more, than the disease itself.  There is no question that in many cases, we are cancer-phobic, more afraid of the disease than the medical evidence says we need to be, and that fear alone can be bad for our health. As much as we need to understand cancer itself, we need to recognize and understand this risk, the risk of cancer phobia, in order to avoid all of what this awful disease can do to us.

In a recent report to the U.S. National Institutes of Health (NIH), a panel of leading experts on prostate cancer, the second most common cancer in men (after skin), said;

“Although most prostate cancers are slow growing and unlikely to spread, most men receive immediate treatment with surgery or radiation. These therapeutic strategies are associated with short- and long-term complications including impotence and urinary incontinence.”

“Approximately 10 percent of men who are eligible for observational strategies (keep an eye on it but no immediate need for surgery or radiation) choose this approach.”

“Early results demonstrate disease-free and survival rates that compare favorably (between observation and) curative therapy.”

“Because of the very favorable prognosis of low-risk prostate cancer, strong consideration should be given to removing the anxiety-provoking term ‘cancer’ for this condition.”

Let me sum that up. Many prostate cancers grow so slowly they don’t need to be treated right away…the unnecessary treatment causes significant harm…and one of the reasons nine men out of ten men diagnosed with slow-growing prostate cancer accept, indeed choose these unnecessary harms, is because “cancer” sounds scary.

Consider more evidence for cancer phobia. In “Overdiagnosis in Cancer,” doctors at Dartmouth classified “25% of mammographically detected breast cancers, 50% of chest x-ray and/or sputum-detected lung cancers, and 60% of prostate-specific antigen–detected prostate cancers,” as “overdiagnosed,” which they defined as “1. The cancer never progresses (or, in fact, regresses) or 2. The cancer progresses slowly enough that the patient dies of other causes before the cancer becomes symptomatic.” The doctors described the negative health effects such patients suffer from a range of treatments that often involve radical surgery and noted; “Although such patients cannot benefit from unnecessary treatment, they can be harmed.”

Add to those harms the damage from stress caused by the diagnosis of cancer, or even the fear of getting it. Chronic stress raises blood pressure and contributes to heart disease. Even more directly as regards cancer, chronic stress weakens the immune system, the very system our bodies need to help prevent, fight, or recover from, the disease itself. and beyond these harms to individual patients, consider the cost of cancer phobia at the societal level.

Rates of diagnosed prostate cancer were higher after regular screening was
instated in 1987, but there was no increase in prostate cancer deaths, and
20-year follow-ups showed that only 5% of these men died of prostate cancer.

The basic biological mechanics of what causes both cancer and heart disease are still inadequately understood and need fundamental research. But the U.S. National Institutes of Health spend about four times as much on cancer research as on heart disease research, despite the fact that heart disease kills about 10% more people (60,000 each year, 25 per day), than cancer. We are spending far more on the second leading cause of death than we are trying to figure out what is much more likely to kill us.

Despite all the progress we’ve made on cancer, a recent Harris poll found that cancer is the most feared disease in the U.S., 41% to Alzheimer’s 31%. (Only 8% of American are most afraid of the leading cause of death in the U.S., heart disease). In August 2011, Cancer Research UK found 35% of Britons feared cancer most, followed by Alzheimer’s at 25%. And this fear is hardly new. 40 years ago the U.S. National Cancer Act of 1971, which declared “War on Cancer“ said “…cancer is the disease which is the major health concern of Americans today.”

Cancer phobia goes even further back. The term itself was coined in an article by Dr. George Crile, Jr., in Life magazine, in 1955, “Fear of cancer and unnecessary operations.” His insights describe conditions today as accurately as they did then: “Those responsible for telling the public about cancer have chosen the weapon of fear, believing that only through fear can the public be educated. Newspapers and magazines have magnified and spread this fear, knowing that the public is always interested in the melodramatic and the frightening. This has fostered a disease, fear of cancer, a contagious disease that spreads from mouth to ear. It is possible that today, in terms of the total number of people affected, fear of cancer is causing more suffering than cancer itself. This fear leads both doctors and patients to do unreasonable and therefore dangerous things.”

Unfortunately, Dr. Crile overlooked the key truth about our fear of cancer: Cancer phobia is hardly just the product of zealous health and environmental advocates magnified by media alarmism. It comes from the innate way we perceive all risks, a process that relies not only the statistical and medical facts, but on how those facts feel. Risk perception is a blend of conscious reasoning and subconscious instinct, and neuroscience suggests that between the two, instincts and emotions have the upper hand. While we’ve been busy studying cancer, we have also learned a lot about the specific psychological characteristics of cancer that make it particularly frightening.

The more pain and suffering a risk involves, like cancer, the scarier it is.

The less control over a risk we feel we have, the scarier it is. Despite great medical progress, cancer is still something that too often can’t be controlled. It is still widely assumed that a diagnosis of cancer is a death sentence.

The more a risk feels imposed on us, rather than the result of something we did by choice, the scarier it is. Many people continue to believe that a majority of cancers are “done to us” by outside forces, despite the medical evidence that environmental cancers (beyond those caused by our lifestyle choices of diet and exercise) make up perhaps 10–15% of all cases.

The greater our “mental availability” about a risk—how readily the risk comes to mind—the scarier it is. Cancer is constantly in the news. And the very mention of the word “cancer” is instantly overwhelmingly negative, a psychological effect called stigmatization that makes it difficult for us to think about things objectively.

“Cancer” is no longer the automatic death sentence it was once feared to be. From 1990 to 2010 the overall death rate from cancer in the U.S.has dropped 22% in men and 14% in women. (Incidence in the U.S. has stayed about the same.) In the U.K., the male mortality rate has dropped 26% and the female rate has declined 16% since 1980, (even while the incidence rate in the UK have increased 22%).

We have learned an immense amount about cancer, allowing us to treat, or even prevent, some types that used to be fatal. But we have also learned a great deal about the psychology of risk perception and why our fears often don’t match the evidence. We are failing to use that knowledge to protect ourselves from the significant, tangible health risks of our innately subjective risk perception system. The proposal of the NIH panel to replace the “C” word with something else that is medically honest but emotionally less frightening is a tiny first step in the right direction to open a new front in the War on Cancer: the battle against cancer phobia.

    But fear is greatest motivator. The funding for cancer research needs that.

    I had cervical cancer years ago ad what I remember most clearly is the oncologist’s greeting to me upon our first meeting”This is a tragedy”. Up to that point I had not been that frightened.

    It is estimated over half a million people died from cancer in 2011 alone and 1.6 million people recieved the diagnosis. While yes there are 12 million survivors the odds of their cancer coming back is a reality. Surviving it doesn’t just end there. The treatments themselves can be deadly. If you do survive it your body is never the same and not just the part where the tumor was or just the scaring. The treatments affect so many different organs and bodily functions and at times put you at risk for developing another type of cancer altogether- ie breast cancer patients/survivors receive radiation to their chests this puts them at risk for developing lung cancer. In my opinion awareness, research and early detection needs much more attention. People should be fearful of the disease but hopeful that if diagnosed they will survive because of people like myself and so many others dedicated to advocating for these things. The reason survival rates increase is because of advocacy and awareness which drives research funding and early detection methods. I watched lung cancer and it’s treatments physically destroy my young father in a matter of months. This form of cancer is the number one cancer killer and receives the least. That’s pretty scary.

    How timely. I’ve got a PSA of 20+ (for the last three tests) so I’m headed off for a biopsy in a week. Naturally apprehensive. But the urologist, a funny lad from Yale, said that at 73 I had a chance of cancer of about 40%–and with a 20+ it was 50%. He said not to worry if I can live with the 10% difference for a few weeks. I’m not sure what he would have said or done if I said that I couldn’t live with it. The last couple of days I’ve had a flu-like headache so I naturally thought I’d die before the biopsy and it had come to do me in. But I feel fine today, not dead yet, and I’ll live to get rectally probed and snipped. So the article and study was right on target. (He also said my prostate was as big as he’d ever felt and he was surprised it wasn’t popping out I was sitting on it half the time. Oh well…

    When I was diagnosed with cancer, my doctor started to cry! It was awful, having to comfort him! Now I’m at 18 years cancer-free with a relatively short treatment period, and I do have to say my doctor over-reacted. I’ve also had a small basal-cell carcinoma and numerous other “scares” which turned out to be nothing. I sometimes wonder if the scare is meant to make you pay for more diagnostic procedures. Your whole body is pre-cancerous, since that means before cancer!!!! If someone tells me something is pre-cancerous, I don’t panic.

    This piece is utterly fascinating, and I’m thrilled to just come across it, as I recently published an post, backed by research, on cancer as the most feared illness in our society (come check it out at http://wp.me/p22afJ-CV to affirm the degree of cancer-phobia permeating our world). I’m about to go back to it and link to your article, to hopefully help people get more of a grip on the realities of cancer, and why it might be safe to feel less afraid. I believe your article can do much to soothe the masses. Thanks for your well-researched input. Candida
