The "War on Cancer" might finally be making good progress -- certainly more progress than most of the wars around the world today. We are making real strides in terms of learning about the causes of cancer, the risks and benefits of various tests used to screen for cancer, and new possibilities for how to cure it.
We're falling short, however, on communicating what we know to patients and their family members. Better communication about treatment options will help millions of people avoid ever developing cancer, and also prevent unnecessarily radical and harmful treatments for those who are diagnosed with cancer.
I got involved in this issue two decades ago when I realized how often the treatment for cancer can be worse than the disease. At the time, I was shocked by how often medications aimed at treating one type of cancer could cause a different type of cancer. And I was also shocked that so many women were undergoing mastectomies they did not need. The research was clear: Those women would live just as long by undergoing a lumpectomy, a far less radical surgery.
My perhaps Pollyannaish solution was to start a nonprofit organization that would bridge the gap between the expensive and extensive research being conducted and what patients understood about which treatments were likely to work best for them.
I soon learned that there were a few well-known cancer charities that were attracting all the donations (from millions of people and every company in the country), and unfortunately, they seemed more focused on organizing highly publicized events rather than actually helping patients get the best treatments. Their well-funded PR staff helped them control what "everyone knows" about how to prevent or cure cancer -- including information that was just plain wrong.
Although over-treatment and misinformation are especially obvious when it comes to breast cancer (for example, there is absolutely no evidence that monthly self-exams save lives), men receive equally confusing messages about prostate cancer. The similarities are uncanny: In both cases, adults without symptoms are strongly urged to get annual prostate or breast cancer screenings that frighten them into thinking they have potentially fatal cancer. In both cases, the diagnosis is less likely to be fatal compared to many other cancers.
And in both cases the treatment can be traumatizing for many (women losing their breasts, men becoming impotent or incontinent), amplifying fear in the general public of even the earliest markers and least lethal forms of these cancers. And so, the cycle continues: People with the earliest or least conclusive diagnoses often opt for the most aggressive treatment, unnecessarily harming their body or body image in ways that the cancer might never have.
There is good news for newly diagnosed patients: persuasive evidence that a sizable percentage of men and women who were diagnosed and treated would have lived just as long (perhaps longer) without treatment, or with much less radical treatment. For women with what used to be called "Stage 0" breast cancer -- and for men with a very slow-growing prostate cancer -- surgery, radiation, and other radical treatments often do more harm than good.
Research has clearly shown that for a substantial minority of patients, "active surveillance" -- no surgery, no radiation, but just regular screening -- is a very safe alternative to treatment. Many doctors know this. But many patients do not, because most doctors are not very good at communicating this kind of complicated "we're not exactly sure what will happen if you don't have surgery" information. And despite billions spent by our government, companies, and charities on finding a cure for cancer, almost nothing is spent on how to explain the risks and benefits of different treatments or "active surveillance" to patients so that they truly understand it.
There's a saying that to carpenters most problems can be solved with a hammer, and to surgeons most problems can be solved with a knife. So I was surprised when an older and very distinguished cancer surgeon said to me, "If patients are choosing unnecessary surgery it means we're not explaining it well."
That's why I like to talk to patients and ask them how best to explain complicated medical information, so that every individual can have the information he or she needs to make the best decisions for him -- or herself. At Cancer Prevention and Treatment Fund, we understand that patients' decisions are based on what they hope and fear and need, not just what they know. So, I'd like to hear from you! Here are our booklets for DCIS patients and prostate cancer screening. I hope these will be helpful to you or anyone you know who might be struggling with these difficult decisions.
