I met a patient recently, a lady I'll call Lisa, who was in her mid-50's and previously completely healthy. She had noticed a lump growing on the right side of her neck, about the size of a tangerine. A few days later, a lump developed on the left.
She was quickly referred to an ear, nose, and throat doctor, who also noticed a growth on her tonsil. A biopsy of the tonsil and one of the lymph nodes in the neck showed a type of cancer called squamous cell carcinoma.
Special testing revealed that Lisa's cancer was caused by the human papillomavirus (HPV). HPV causes a few other types of cancer (including cervical cancer in women), but HPV-related throat cancer is becoming increasingly common. These types of throat cancers often develop between the ages of 50 and 75. Historically, the risk factors for throat cancers have been mainly alcohol and tobacco, so to find a throat cancer in a non-smoker and non-drinker used to be uncommon. That is no longer the case.
The good news for Lisa is that HPV-related cancers are very curable. With a combination of chemotherapy and radiation (a common approach in Canada), or sometimes surgery with radiation afterward (a common approach in the US), cure rates approach 90% in patients like Lisa. In this business, a 90% cure rate is excellent. (Side note: we have just completed a trial comparing the US and Canadian approaches - results next year).
But Lisa was very hesitant for any treatment. She shared that she'd seen a naturopath prior to visiting us, and the naturopath had told her that the cancer was incurable. She was told that standard treatments could 'hold the cancer' or cause it to shrink 60% of the time, but that eventually it would grow and cure was not possible. Lisa's husband, who also came to both appointments, confirmed what the naturopath had said.
Having delivered that information, the naturopath then sold her some 'treatments' that really don't do anything against cancer, including high-dose vitamin C. Understandably, having been led to believe that her cancer was incurable, Lisa was hesitant to try the treatment recommended by our head-and-neck cancer team.
Sometimes people think that alternative treatments are harmless, but there is the real potential for harm here. Lisa's cancer is curable now, but it might not be curable in a few months. If it spreads to other parts of her body, it will be incurable and would then end up taking her life.
The naturopathic industry has become a Wild West of inaccurate medical claims. For some stories of what goes on behind the scenes, check out a website run by a former naturopath (Britt Marie Hermes) who was shocked by what she saw and is now trying to get the word out (www.naturopathicdiaries.com). These wild medical claims harm our patients: they provide false information, they sell expensive treatments that don't work, and in some cases (like a patient who is misled into abandoning curative treatments) can cost lives.
We need oversight of naturopaths. As a stark contrast, let's consider what would happen to me, as an oncologist, if I told Lisa the same thing that her naturopath reportedly said:
And these would all be reasonable punishments for such a serious transgression.
Why do we have a double standard, where a doctor would be seriously punished for actions that seem common in some naturopathic offices?
After a long, honest discussion, Lisa has opted to undergo treatment. We won't know if she's cured for five years. But her chances are excellent. If she had listened to her naturopath, we might have lost our chance at a happy ending.
Naturopaths are profiting by proving false medical information that harms our patients, but helps their own bottom line. No one is stepping in to stop them. We need our government and health regulators to step in and provide oversight in the Wild West of alternative treatments.

The following is an excerpt from Taking Charge of Cancer: Chapter 6 - Is Your Doctor’s Recommendation Best for You?
For many types of cancer, the best treatment approach is well-established. Sometimes surgery is the #1 choice. This is true for early-stage breast and colon cancers. Other times, it's radiation as the top choice. This is the case for some head and neck cancers. When the best approach is clear, there is very little debate.
But in some scenarios, the debate is intense. Let’s consider a patient with stage I lung cancer. Stage I means that the lung cancer is small - 5 cm (2 inches) or less - and hasn’t spread to any other parts of the body. These cancers are highly curable. The disagreement over how this patient should be treated illustrates some of the biases inherent to medicine.
For more than 50 years, the standard treatment in this situation has been surgery, giving the best chance of cure. Radiation has been the second-choice treatment option, used mostly for patients who were too unwell to undergo surgery.
But the tides are shifting. A new type of precise radiation treatment has been developed, stereotactic radiation. The results have been very good, generally with few side effects. Some doctors are now calling for stereotactic radiation to replace surgery as the treatment of choice. Ideally, we would now have randomized trials to compare these two options, but we don’t. A few were tried, but not enough patients joined to allow for any strong conclusions. [You can read the report from two of the trials here].
Since we don’t have randomized data, the truth is that we don’t know for sure which of the two treatment options is better, because we have incomplete evidence. If you took a poll of doctors, some might favor surgery, some might favor stereotactic radiation, and some might be undecided.
The problem is that doctors’ beliefs are heavily dependent on what they do for a living. If you ask radiation doctors, 80 percent believe that surgery and radiation are equally effective in this situation. If you ask surgeons, the number is only 20 percent. And if you ask a neutral party (in this case, lung specialists who don’t do surgery or radiation), the number is almost exactly in the middle: 49 percent. 
Clearly, doctors are being swayed more by their profession than by the scientific evidence. We see the same pattern in the treatment of men with early prostate cancer: the large majority of surgeons believe that surgery is better, but the large majority of radiation oncologists think that radiation and surgery are equally effective. 
The same biases also arise when you ask doctors about side effects of treatment. Radiation oncologists predict worse quality of life after surgery than surgeons do, and surgeons predict worse quality of life after radiation than radiation oncologists do. 
It appears that doctors have a rosy view of the treatments that they provide themselves and a less rosy view of treatments provided by other specialties.
The Impact of Biases
Because of these biases, the type of doctor that a patient meets can have a big impact on the type of treatment that he or she gets. For men with early prostate cancer, a big determinant of treatment choice is the type of doctor the patient is seeing, whether it’s a radiation doctor or a surgeon.  If you see a surgeon, you are more likely to have surgery, and if you see a radiation doctor, you are more likely to have radiation. The type of physician seen is even more strongly associated with the ultimate treatment choice than the patient’s own preferences about side effects! This suggests that physician bias is spilling over into treatment decisions. We should be providing patient-centered care, where treatment is based on the beliefs and preferences of individual patients, but this data suggests that we are not. 
The bottom line is that specialists tend to favor whichever treatment they themselves provide. This bias, specialty bias, can be a major problem for patients. Patients rely on doctors to provide balanced information so that they can make an informed decision. If our opinion is skewed in favor of our own treatment—favoring our own specialty—can we really provide balanced information? Compounding the issue is that once the bias sets in, doctors may be less willing to do studies to test their own treatments, for fear that they may lose out.
Tom Treasure, MD is a British thoracic surgeon who has dedicated much of his career to undertaking rigorous assessments of surgery, including randomized trials, and challenging conventional beliefs. In discussing the debate about the optimal treatment of early lung cancer (the comparison of surgery and stereotactic radiation we discussed above), he states that “in an era when evidence is expected for treatments, the fact that these interventions have still not been properly assessed is shameful.” 
A big problem with these turf wars is that patients are caught in the middle, with no easy way to determine the best approach. “Trust me, I’m your doctor does not have the ring of truth,” continues Dr. Treasure, “when different doctors claim to know what is best while consistently failing to encourage trials to put their beliefs to the test.”

For a patient diagnosed with cancer today, there’s not time to wait for future trials to be completed. Here are some questions you can ask of your treatment team:

Insomnia is a common problem in cancer survivors. In women previously treated for breast cancer, for example, approximately one-third are diagnosed with insomnia. Sufferers of insomnia can have difficulty falling asleep, and they awaken often during the night, only to find themselves unable to get back to sleep. This can lead to tiredness, low energy levels, difficulty with concentration, and mood disturbances.
Insomnia is often treated with medications, but the best treatment has generally been considered to be cognitive behavioral therapy (CBT). CBT combines cognitive therapy (a type of psychotherapy where unhelpful thought patterns are challenged in order to change behavior) with better habits, including relaxation in the evening and avoiding stimuli. CBT is better than medications in treating insomnia, but CBT can be hard to access, due to cost and availability of psychotherapists.
There is a new option that holds promise for treating insomnia, a form of Tai Chi called Tai Chi Chih (TCC). TCC combines slow, deliberate physical movements with relaxation and mediation, and is termed a 'movement meditation'. TCC has been shown to help with insomnia in older adults, and also improves depression and fatigue.
In a new study published last week, researchers from UCLA compared CBT (the current 'best treatment' for insomnia) with TCC in a group of breast cancer survivors with insomnia. This was a randomized study, where women were assigned at random to one of two groups: one group received CBT, and the other received TCC. Randomized studies are important in medicine, because they allow for the most unbiased comparison between two treatment approaches. The UCLA researchers used a special study design where they wanted to show that TCC was not worse than CBT. If successful, it would mean that there are two 'gold standard' treatments for insomnia, CBT and TCC.
The TCC approach used in the study was based on a TCC program described in the book T'ai Chi Chih! Joy Thru Movement by Justin Stone. It consisted of weekly sessions, two hours long, and lasted 3 months in total.
Ninety women entered the study and were allocated to one of the two groups. In the CBT group, 44% showed an insomnia treatment response by 15 months. In the TCC group, the corresponding number was 47%. The two groups showed similar improvements in other measures, such as sleep quality.
We can conclude that TCC is essentially just as good as CBT. Although this study looked only at breast cancer survivors, it's reasonable to assume that the benefits would be seen in survivors of other types of cancer, especially since TCC has been previously shown to be helpful in other settings.
If you are a cancer survivor suffering from insomnia, TCC might be worth a try.
Some alternative health websites promote conspiracy theories of 'hidden cures' for cancer. These conspiracy theories are false, and they are harmful to patients.
Let's look at two of these claims to see why they don't make sense. Then I'll explain why these conspiracy theories hurt patients.
Conspiracy Theory #1: There's a cure for cancer, but doctors are hiding it.
The premise with this statement is that since doctors make a living from treating cancer, if there was a cure, we’d all be hitting the unemployment lines. So we just clam up and keep the cure to ourselves.
There’s one obvious problem with this logic: doctors and their family members die of cancer too. I have known cancer doctors who died of cancer, and some of my colleagues have lost their spouses or children to cancer. If there were a cure that we were not sharing with the public, certainly we would use it for ourselves and our loved ones. Does it seem logical that an oncologist would let her child die, or die herself, just to keep a secret cure hidden? No sane person would do that.
The other problem with this theory is that doctors and researchers spend huge amounts of unpaid time working on cancer research, often in the evenings and on weekends, away from family and friends. Many of us also donate to cancer research. For my upcoming book, Taking Charge of Cancer, which focuses on helping patients get top-quality care, I've donated all the author royalties to cancer research. Why would we waste so much time and money if there was already a cure?
This idea just doesn't make sense.
Conspiracy Theory #2: Pharmaceutical Companies Are Hiding the Cure
In this version, the doctors are blameless, but the magic bullet is hidden by a greedy pharmaceutical company that wants to keep the real cure hidden so that instead, it can continue to sell drugs that don’t work as well.
Let’s consider the economics of this. We’ll imagine that a pharmaceutical company has a magic bullet, a single pill that will cure all cancers. Is it better to sell the single pill, or to sell less-effective treatments that patients have to keep taking for years?
Governments and insurers pay a lot of money for medical treatments. In many countries, the decision about how much to pay for a drug (or whether to pay for it at all) depends on its benefit compared to the cost. A drug that increases someone’s life span by 10 years is worth much more than a drug that gets only an extra month.
To calculate if a drug is worth paying for, health economists use a value called the quality-adjusted life year, or QALY. If a drug adds one year of high-quality time to your life (in other words, during that extra year, you are not sick with side effects or disabled), it adds one QALY. This allows payers to decide which medical treatments are worth funding. If one treatment costs $100,000 per QALY and another costs $500,000 per QALY, it makes sense to prioritize the cheaper one over the more expensive one.
Some countries draw a line in the sand dictating the maximum they will pay per extra QALY. A cost of $100,000 per QALY is a reasonable line. If a new drug comes along that costs $500,000 per QALY, it would not be funded with that cutoff. Some countries have higher or lower cutoffs or no cutoff at all.
If we were willing to pay $100,000 per QALY, we can calculate the value of that magic bullet hidden by a drug company. If you give the magic bullet to a 30-year-old patient who is about to pass away from a terminal cancer, she would be cured and might be expected to live to age 80. As long as she has good quality of life, you’ve given her 50 extra QALYs, and the drug company could reasonably charge $5 million ($100,000 per QALY x 50 QALYs). If, instead, the drug company offered a series of drugs that kept the patient alive for five years, the most it could get under this system would be $500,000.
With those numbers, the economic value of a magic bullet would be staggering. Keeping a magic bullet locked away in a safe would be the worst business model of all time.
How Conspiracy Theories Harm Patients
These conspiracy theories often include a statement that there is a hidden alternative cure for cancer, perhaps related to diet or vitamins. This is also untrue. Click to read an article from a former naturopath debunking many alternative cancer remedies.
The problem is that for many patients who have a curable cancer, the window of time to cure that cancer is not very long. If too much time passes without treatment, the cancer can spread and no longer be curable. If a patient decides to forgo conventional treatment and instead pursues alternative treatments, the cancer can become incurable in that time. There is no going back.
In my experience as a cancer doctor, only a small minority of patients choose to forgo a potentially curative treatment because of beliefs in a conspiracy theory or an alternative cure. But for those who have made that decision, the consequences I have seen have been tragic. In some cases, patients have changed their mind after it became clear that the cancer had grown, wanting to pursue treatment then, but the chance of cure was gone.
These conspiracy theories are not harmless.
What can we do to fight these conspiracy theories? It can be difficult to stamp out fake health information, as we've seen in the battle against false vaccine claims. But one way to start is by standing up for the truth. When we are faced with a claim like one of the ones above, we need to say - or post - that the claim is false and harmful to patients.
We protect our families against all sorts of household dangers. But many of us don't check our houses for radon gas, even though radon causes thousands of cases of lung cancer every year.
You Can't Smell or See Radon
Radon is a radioactive gas formed by the breakdown of uranium, which is naturally found in rocks and soil. Radon has no color, smell, or taste, making it undetectable to our senses.
Radon gas can enter a house through any small gaps where the house touches dirt. These gaps can include construction joints, cracks in the foundation or floor, and the spaces around pipes. Radon can also come from some sources of water, and from certain building materials that contain small amounts of uranium. In the outdoors, radon isn't a problem, since it is diluted by fresh air. But in a house, radon can accumulate to high levels.
Radon gas naturally breaks down into radioactive particles that we breathe in. Those particles settle in our lungs and deliver radiation to our healthy lung tissues. That radiation can cause lung cancer.
A Significant Risk of Cancer
Lung cancer is responsible for more deaths than any other cancer, and radon itself causes one out of every six lung cancer deaths.
According to Health Canada, if you are a non-smoker who is exposed to high levels of radon, your lifetime risk of lung cancer is about one-in-twenty. For smokers, the risk is substantially higher. A smoker who is exposed to those high levels of radon has a lifetime risk of lung cancer of one-in-three.
It is estimated that about 400 Americans and 40 Canadians die of radon-related lung cancers each week.
Testing is Recommended
Some geographic regions are more likely to have higher levels of radon, based on the underlying amount of uranium in the earth in that area. But even in low-radon areas, some houses can have high levels of radon, and the only way to know is to check.
Home radon testing is recommended by both the U.S. Environmental Protection Agency and Health Canada. Testing can be done by purchasing a do-it-yourself test kit, or by hiring a radon testing service. The do-it-yourself tests provide a kit that you send back to a laboratory once the testing is complete. Setting up the test kit takes only a few minutes.
