Breast cancer survivor  @coffeemommy (Stacey Tinianov) gave me permission to reblog the  article below, which she wrote following the #abcDrBchat tweetchat about lung cancer Tuesday December 10 2013.  She’s written an excellent clarification of the differences between cancer prevention, risk reduction, and screening.

Prevention vs. Risk Reduction vs. Screening
by coffeemommy

After a series of particularly frustrating exchanges, I have decided it will take more than 140 characters to not only explain the distinction between prevention, risk reduction and screening in ALL cancers but to also explain why a distinction is so critical.

Prevention: definition 1. To keep from happening

Reality check:

• The only way to prevent breast cancer is to not have any breast tissue.
• The only way to prevent lung cancer is to not have lungs.
• The only way to prevent skin cancer is to not have that
  useful covering over your flesh and bones.

You get the idea.

But wait! There’s this list you received from your doctor’s office, right? Certainly it’s titled something provocative like: “Prevent Breast Cancer” and includes some or all of the following:

• Eat a well-balanced, low-fat diet
• Exercise regularly
• Limit alcohol intake
• Maintain a healthy weight
• Annual mammograms beginning at age 40

I did all those.

And I was diagnosed at age 40 with two tumors of invasive ductal carcinoma, diffuse DCIS and lymph node involvement in my left breast. Did I misunderstand the rules for preventing breast cancer and do something wrong? No. I didn’t. I tried to reduce my risk and it didn’t work. The above list may be a compilation of helpful hints but, even collectively, they do not prevent breast cancer, they help reduce risk.

RISK REDUCTION

Risk reduction in the spectrum of the healthcare industry attempts to lessen our chances of receiving a diagnosis by removing potential harmful exposures and/or behaviors from our lives and, in some cases, replacing them with behaviors that can help fend off disease.

To use skin cancer as an example, we can use sunblock liberally but we are merely attempting to reduce our risk. Skin cancer is still a possibility and a combination of exposure and genetics may render our efforts utterly useless.

Never-smokers without lung cancer who may feel they can cross malignant non-small cell carcinoma off their worry list should meet Janet Freeman who “never smoked anything except a salmon.”

And there are tens of thousands more who followed the list of “prevention” tactics but were diagnosed anyway. Specifically, even if you are a never smoker, you may still have some of the following risk factors for lung cancer:

• Exposure to radon
• Exposure to air pollution
• Exposure to second-hand smoke
• Exposure to asbestos
• Exposure to carcinogens we don’t even know about yet
• Exposure to previous cancer treatments
• Genetic predisposition to lung cancer

Risk reduction is limiting exposure to the above but does not guarantee prevention. And a genetic predisposition is hard to shy away from.

SCREENING

If we refer back to the sage if woefully mis-titled “Prevent Breast Cancer” document above, I’d like to call out the last ‘prevention technique’ – the oft-touted annual mammogram.

People. People. People. Regular mammograms don’t PREVENT breast cancer OR reduce risk. EVER.

Mammograms are screening tools. Regular screening is encouraged so anomalies can be found as early as possible,be treated as quickly as possible and, hopefully, result in a better longer term outcome.

DISTINCTION is NOT A SEMANTICS ISSUE

This is not a tomato – tomato (c’mon, you’re supposed to pronounce those differently when you read them!) issue. Why is the terminology distinction important? Three reasons bubble to the top for me:

• Continued Diligence: Individuals must remain diligent in personal and professional screening even when they”do everything right” on the risk reduction list. Mammograms don’t “Save the ta-tas” they simply alert people as to whether or not their breasts are trying to kill them. I can personally attest to the fact that people who follow all the published rules for how to prevent breast cancer, and get a mammogram at 40, still get breast cancer.

• Removing Stigma and Eradicating Blame & Shame: According to anecdotal data, the most common question lung cancer patients field is, “How long did you smoke?” If you advertise risk reduction as prevention you are perpetuating a falsehood. Perpetuating the idea that cancers are preventable implies that, when a diagnosis is given, somebody did something WRONG.

• Redirecting Research Focus: While a list of ways to reduce risk for disease is helpful, such a list is not a magic bullet. Already genomic research is leading to personalized treatments. We need to expand efforts in this area. When the general public finally realizes that no one is “immune” to a cancer diagnosis, more focus can be applied in the appropriate areas.

Cancer sucks, no one “deserves” it. Please don’t propagate a false sense of security or imply wrongdoing by patients who are diagnosed by claiming cancer is preventable. Please choose your words wisely.
