10 Breast Cancer Myths

Marisa Weiss M.D. is the president and founder of breastcancer.org.

What is your risk of breast cancer? What about antiperspirants and breast cancer? What you don’t know CAN hurt you. Misinformation can keep you from recognizing and minimizing your own risk of breast cancer or getting the very best possible care. Arm yourself with the facts.

Here are ten common myths about breast cancer:

1. Breast cancer only affects older women.
No. While it’s true that the risk of breast cancer increases as we grow older, breast cancer can occur at any age. From birth to age 39, one woman in 231 will get breast cancer (<0.5% risk); from age 40-59, the risk is one in 25 (4% risk); from age 60-79, the risk is one in 15 (nearly 7%). Assuming you live to age 90, the risk of getting breast cancer over the course of an entire lifetime is one in 7, with an overall lifetime risk of 14.3%.

2.If you have a risk factor for breast cancer, you’re likely to get the disease.
No. Getting breast cancer is not a certainty, even if you have one of the stronger risk factors, like a breast cancer gene abnormality. Of women with a BRCA1 or BRCA2 inherited genetic abnormality, 40-80% will develop breast cancer over their lifetime; 20-60% won’t. All other risk factors are associated with a much lower probability of being diagnosed with breast cancer.

3. If breast cancer doesn’t run in your family, you won’t get it.
No. Every woman has some risk of breast cancer. About 80% of women who get breast cancer have no known family history of the disease. Increasing age – just the wear and tear of living – is the biggest single risk factor for breast cancer. For those women who do have a family history of breast cancer, your risk may be elevated a little, a lot, or not at all. If you are concerned, discuss your family history with your physician or a genetic counselor. You may be worrying needlessly.

4. Only your mother’s family history of breast cancer can affect your risk.
No. A history of breast cancer in your mother’s OR your father’s family will influence your risk equally. That’s because half of your genes come from your mother, half from your father. But a man with a breast cancer gene abnormality is less likely to develop breast cancer than a woman with a similar gene. So, if you want to learn more about your father’s family history, you have to look mainly at the women on your father’s side, not just the men.

5. Using antiperspirants causes breast cancer.
No. There is no evidence that the active ingredient in antiperspirants, or reducing perspiration from the underarm area, influences breast cancer risk. The supposed link between breast cancer and antiperspirants is based on misinformation about anatomy and a misunderstanding of breast cancer.

6. Birth control pills cause breast cancer.
No. Modern-day birth control pills contain a low dose of the hormones estrogen and progesterone. Many research studies show no association between birth control pills and an increased risk of breast cancer. However, one study that combined the results of many different studies did show an association between birth control pills and a very small increase in risk. The study also showed that this slight increase in risk decreased over time. So after 10 years, birth control pills were not associated with an increase in risk. Birth control pills also have benefits:

  • decreasing ovarian and endometrial cancer risk
  • relieving menstrual disorders, pelvic inflammatory disease, and ovarian, and cysts
  • improving bone mineral density

As with any medicine, you have to weigh the risks and benefits and decide what is best for you.

7. Eating high-fat foods causes breast cancer.
No. Several large studies have not been able to demonstrate a clear connection between eating high-fat foods and a higher risk of breast cancer. Ongoing studies are attempting to clarify this issue further. We can say that avoidance of high-fat foods is a healthy choice for other reasons: to lower the “bad” cholesterol (low-density lipoproteins), increase the “good” cholesterol (high-density lipoproteins); to make more room your diet for healthier foods, and to help you control your weight. Excess body weight, IS a risk factor for breast cancer, because the extra fat increases the production of estrogen outside the ovaries and adds to the overall level of estrogen in the body. If you are already overweight, or have a tendency to gain weight easily, avoiding high-fat foods is a good idea.

8. A monthly breast self-exam is the best way to diagnose breast cancer.
No. Digital mammography or high quality film-screen mammography is the most reliable way to find breast cancer as early as possible, when it is most curable. By the time a breast cancer can be felt, it is usually bigger than the average size of a cancer first found on mammography. Breast examination by you or your healthcare provider is still very important. About 25% of breast cancers are found only on breast examination (not on the mammogram), about 35% are found on mammography alone, and 40% are found by both physical exam and mammography. Keep both bases covered.

9. I’m at high risk for breast cancer and there’s nothing I can do about it.
No. There are several effective ways to reduce-but not eliminate-the risk of breast cancer in women at high risk. Options include lifestyle changes (minimize alcohol consumption, stop smoking, exercise regularly), medication (tamoxifen, also called Nolvadex); and in cases of very high risk, surgery may be offered (prophylactic mastectomies, and for some women, prophylactic ovary removal). Be sure that you have consulted with a physician or genetic counselor before you make assumptions about your level of risk.

10. A breast cancer diagnosis is an automatic death sentence.
No. Fully 80% of women diagnosed with breast cancer have no signs of metastases (no cancer has spread beyond the breast and nearby lymph nodes) when first diagnosed. Furthermore, 80% of these women live at least five years, most longer, and many live much longer. Even women with signs of cancer metastases can live a long time. Plus promising treatment breakthroughs are becoming available each day.

Delightfully Wrong

It makes me smile to think of just how good it can feel to be wrong about something. I was very wrong when I did a blog post referencing the first presidential debate, calling for Barack Obama to quit being "Mr. Nice Guy."

In yesterday’s debate, Obama was firm and thoughtful — and centered. It was perfect. In retrospect, it was perfect of him to let McCain’s condescending approach in the first debate fall unopposed like rain.

When I consider what it will take to have peace on earth become a reality, I am clear that it will be through individuals transformed in critical mass as Deepak would say. For my own part, I see my transformation as a journey barely begun. This is particularly true when there is an opportunity to witness the calm Obama displays while under pressures I cannot begin to comprehend.

Obama’s grace in both debates, his presidential bearing and intelligence are very inspiring. Last Saturday I was lucky enough to see Obama speak in Virginia.

I’ve been fortunate enough to see Barry Goldwater, Ronald Reagan, John Kerry (twice!) and now Barack Obama. Obama’s presence is the most impressive to me of all of these. This is a man of great strength and amazing calm.

And I couldn’t be happier to be wrong.

When Spiders Attack


On my way home from work last Friday I noticed an ache, a pain in my leg. I was driving, so I reached down and felt a blazing heat emanating from my shinbone and felt as though my tennis socks were cutting off the circulation to my leg.

Upon arriving home it became clear that I had been a mid-day snack for an opportunistic arachnid! I figure

No More Backaches

Balancing the upper back/chest area is important for anyone who sits at a desk, hunched over a computer (or anything else) for a good portion of the day. If you’re wondering why that area between your shoulder blades frequently bothers you, consider this explanation.

Why do I hurt?

Think of the position your body is in. Your shoulders are rounded forward, your belly is loose, and your neck and head are forward slightly. Spend a lot of time in this position and the pectoralis muscles (i.e. the pecs) that go from your sternum (breast bone) out to your shoulders become shorter than they would be if you sat up straight all the time. In essence, they’re tight. The pecs need to be lengthened to keep your upper body in balance.

If your chest/pecs are tight, it’s a good bet that the muscles between the shoulder blades are a little too long (i.e. loose or weak) and need to be strengthened. And, with the weight of your head jutting forward, it creates some tension in the upper back muscles that have to hold your head out like that, versus if your head were in better alignment with your spine and could (more or less) rest itself right on top with little effort.

What can I do about it?

Let’s not make this more complicated than it has to be:

• Loosen/open/stretch out the upper chest (Expose your heart to the world!)
• Strengthen/tone the upper back
• Optional: massage (Because it feels good, and it’s good for you.)

To loosen/stretch the upper chest
If you have a partner, you can do Press Open the Chest. Otherwise, interlace your fingers behind your back, press your palms together, straighten your elbows as much as possible, press your shoulders down (away from your ears) and at the same time lift your arms as close to horizontal as you can. There’s another great pectoralis stretch you can do by yourself, which I wrote up in my book Massage in Minutes, but copying it would make this column way too long this week. (If you have the book, it’s on page 101.) But use your intuition. Think about opening up and expanding your chest. It’s not rocket science – you can do it!

To strengthen/tone the upper back
Squeeze your shoulder blades together and hold for a 2 or 3 seconds, then release. Do 10 – 15 repetitions every one or two hours while you’re working. It doesn’t have to be more difficult than that.

Recommended massage
Grab a partner and try any of these techniques from the archives. You don’t need to get undressed, and you could do them right in your cubicle!

Want it?……Be it!

All this talk about Enlightenment, Oneness and Christ Consciousness, seems like some are and some aren’t. But who is really and what makes it so?

Here’s the answer: Everyone is, because everyone is being.
Everyone is enlightened. Enlightenment is your natural state. You seek it, but can’t find it. Why? Because in order to find it..it would have to be separate from you. Enlightenment has to be realized. Meaning, it has to be your conscious awareness.

Let’s say you are a man believing to be a dog. You are walking on all fours and barking. You come to me and say, I want to be a man. I would look puzzled at you, because I see you are a man and I ask myself, why does he not see it?

You want to be a man? Simply stop being a dog.

So it is too with Enlightenment. You want Enlightenment, but you already have it. You already are everything you ever hoped to be right now.

Now, you may ask, but why am I not experiencing enlightenment (Bliss: Peace, Love and Joy all at the same time)? In order to experience anything you have to be aware of it. It is not your awareness, because you focused your attention on seeking it.

Everything we believe to be true has to be demonstrated in action, in order for it to become our experience. The action of seeking is the demonstration of "not having", so "not having" becomes your experience.

As with Enlightenment so with everything in your life. Want it? Be it!
