A national bestseller! Breast cancer surgeon Dr. Kristi Funk offers a comprehensive and encouraging approach to breast care and breast cancer. Empower yourself with facts and strategies to understand your breasts, reduce your cancer risk, and open your eyes to interventions and treatments.

Most women don't want to hear about breast cancer unless they have it and need to make some decisions, but these days news about breast cancer—the number one killer of women ages twenty to fifty-nine—is everywhere. Chances are you know someone who has had it. But did you know that choices you make every day bring you closer to breast cancer—or move you farther away? That there are ways to reduce your risk factors? And that many of the things you've heard regarding the causes of breast cancer are flat-out false?

Based on Dr. Kristi Funk's experience as a board-certified breast cancer surgeon, she knows for a fact that women have the power to reduce breast cancer risk in dramatic ways. Many women believe that family history and genetics determine who gets breast cancer, but that's not true for most people. In fact, 87 percent of women diagnosed with breast cancer do not have a single first-degree relative with breast cancer.

This book will help you:

• Learn the breast-health basics that every woman should know
• Reduce your cancer risk and recurrence risk based on food choices and healthy lifestyle changes backed by rigorous scientific research
• Understand the controllable and uncontrollable risk factors for breast cancer
• Outline your medical choices if you're at elevated risk for or are already navigating life with breast cancer

There have been few solid guidelines on how to improve your breast health, lower your risk of getting cancer, and make informed medical choices after treatment—until now. With her book available in 10 languages and in more than 30 countries, Dr. Funk is passionate about her mission of educating as many women as possible about what they can do to stop breast cancer before it starts.

BREAST HEALTH BASICS

CHAPTER 1

Breast Care ABCs

Take it from someone who’s around breasts all day, every day, and has been known to dream of them at night—women can have very emotional associations with their breasts. It takes a strong sense of self, which I hope we all strive to achieve, to say, “I am not my breasts,” because breasts connect in undeniable ways to femininity, sexuality, body image, and womanhood. Our feelings about our breasts run the gamut from pride in their shape and size, to awe over their milk-producing and life-affirming function, to trepidation and dread that someday they may give us cancer. To this last point, despite our fears, there have been few solid guidelines on how to improve your breast health, lower your risk of getting cancer, optimize your outcomes if you’re faced with a diagnosis, and make informed medical choices after treatment—until now.

I’d like to start off here with a few basics about breast health: the parts and functions of your breasts, surprising facts about the “girls,” and how to take good care of them so you live a long, vibrant life. Understanding the breasts you’re caring for will ultimately go a long way to reducing their cancer risk. While you can’t control all your risk factors—some, like being a woman and getting older, are nonnegotiable—you can influence and reduce more than you may know by recognizing the factors that are under your control and then adjusting your life choices accordingly.

BREASTS 101

When it comes to your chest’s general anatomy, breasts remind me of a funky Jell-O fruit salad. Imagine one of your breasts as many bunches of grapes that you’re holding by the top of the largest stems (at the nipple). As you picture these bunches, see all the tiny connecting stems as the tubes that carry milk out of the nipple during lactation (they exist whether you ever get pregnant or not). The stems all connect to grapes, which represent the milk-producing lobules of your breast. The entire breast has fifteen to twenty lobes (grape bunches), and all the stems coalesce toward the nipple, with eight to twelve milk ducts opening on your nipple’s surface.

Now, push that entire bunch of grapes and stems, which together comprise what we call glandular tissue, into a mold of Jell-O that’s shaped like your breast and sits on top of your chest wall muscles. (By the way, imagine if Tupperware actually made breast molds. They’d make a killing at “bye-bye breast” parties—or as one of my patients called hers, “Ta-ta, ta-tas!”) The Jell-O represents the supportive structures that surround the breast gland, composed of stroma (a kind of connective tissue), adipose tissue (fat), ligaments, lymphatics, and blood vessels. The lobules and ducts, or grapes and stems, are usually what become cancerous (milk ducts alone are responsible for 75 percent of all breast cancers), but the Jell-O rarely does. For example, a Mayo Clinic review of all breast cancers in women over fifty-nine years old showed that a stromal-based breast cancer, called primary breast sarcoma, accounted for only 0.0006 percent of breast malignancies.¹

Breasts range in size from absent, as seen in a rare disease called Poland Syndrome, to ones that swing down to your knees. Cups go from AAA to L—with the average American cup size being a D; Russia, Sweden, Norway, and Finland have cup sizes larger than D; Australia, France, Italy, the UK, Canada, and South America average a C; in Africa and Asia, women are A/B. Few women have a perfect match. In most, the left breast is up to 20 percent larger than the right (sudden one-sided changes in size are not normal, so if that happens, see your doctor). Your breast size and “perkiness” mostly come from a genetic patchwork of markers handed down from both of your parents to you, plus nutrition and the influence of estrogen, progesterone, insulin, and growth factors during your early years, puberty, pregnancy, lactation, and menopause. Fatness, exercise, aging, skin quality, and hormone use also influence size and shape. Since your breasts contain a genetically predetermined amount of fat, your breasts expand when you do. And contrary to what you may have heard, there’s no direct connection between the size of your breasts and your risk of getting breast cancer.

Your actual breast takes up more space on your body than you probably realize—a point to keep in mind when you do your breast exam every month, as I’ll discuss next. The girls aren’t limited to the two fleshy mounds nestled into your bra. Each breast technically goes all the way up to your collarbone (the clavicle superiorly), centrally to your breastbone (the sternum medially), down to the curve you associate with being the bottom of your breast (the inframammary fold inferiorly), and off to the side of your chest wall (the anterior border of the latissimus dorsi muscle laterally). Another bit of breast tissue extends like the point of a teardrop toward the armpit, called the axillary tail, located just beneath the hair-bearing part of your axilla. Sometimes this tissue actually extends into the armpit itself, which is called axillary accessory breast tissue. When rather pronounced, it bulges out, covered by skin. Depending on whether this happens on one or both sides, you might feel as though you have three or four breasts. An axillary accessory nipple could even connect that breast tissue to your skin, and yes, this means you could actually breastfeed from your triple nipple one day.

All breasts are lumpy, not just cancerous ones. Who in the world ever referred to breasts as melons? Did that person ever feel a breast before? Melons are uniformly firm, round, and very smooth—and they don’t budge when you poke them. The natural terrain of the breast is more like a mountain range with peaks and valleys covered in a blanket of snow (fat) and then wrapped in skin. When you run your fingers across that skin, the snow feels soft until you push deep enough to feel a mountain peak, and with a valley on both sides, that peak sure feels like a lump. The only way to trust that that’s a mountain and not a malignant intruder is to either see a doctor, or to know that it’s been there forever and it’s just your normal anatomy. All breasts have lumps, breasts are lumps, and they feel lumpy. The denser your tissue, the lumpier you feel. Genetics determine breast density, as do the estrogen levels in your body.

Lastly, there’s the surface of the breast. Arteries and veins circulate blood flow to nourish the breast skin, and in lighter-skinned ladies, sometimes we can see the veins rather clearly; also, conditions that increase blood flow will dilate those veins, making them more apparent— especially after exercise, or during pregnancy, or in certain cancers. Nipples can be dark or light, smooth or textured, pointing out, level, or inward, and range in size from flat to a pencil eraser or sugar cubes—it’s all normal. The colored skin around the nipple base is called the areola, and its diameter varies from dimes to saucers, generally 1.5 inches to 4 inches (4–10 centimeters). Some people have additional nipples, called supernumerary nipples, located along two vertical “milk line” arcs from the armpits to the normal nipples to the left and right groin. Occurring in 1 per 8,000 people, these either look like flat moles or have a raised bump.² Celebs with extra nipples include Mark Wahlberg (three) and Harry Styles (four), so no shame there.

If you zoom in on the areola, there’s so much more to see. All women have hairs that grow at the areolar edge coming from hair follicles. We have fifty million follicles on our skin, so sometimes a few unwelcome strays grow right there. They usually show up in response to hormone changes: puberty, pregnancy, menstruation, menopause, or birth control pills. You can safely tweeze them out or get electrolysis. Tweezing sometimes leads to ingrown hairs, which then cause tiny raised pimples and white sebum to collect. Makes you wonder why you thought tweezing would make the area more attractive. Areolar bumps called Montgomery glands are tiny sebaceous glands whose function is to lubricate the nipple (per textbooks), but since that seems like a fairly useless function and doesn’t even make sense anatomically since they are not on the nipple, I just tell people they are normal and benign and won’t go away no matter how much you squeeze them. You can also get tiny blackheads at the edge of the areola; just wash the area and occasionally exfoliate as you would do to your face at night. If you notice an itchy, scaly, flaky rash on your nipple or areola, call your doctor.

MORE NIPPLE FUN FACTS!

• Some people are born without nipples, which is called athelia. There are about seven thousand diagnosed cases worldwide.

• Nipple stimulation and genital stimulation affect the same part of the brain. One-third of women can reach orgasm solely through having their nips caressed.

• If you use a magnifying glass to examine the areola, you will find hairs growing on the areolar border of all adult living human beings.

• When supernumerary nipples occur outside the milk line, they’re called ectopic, and can be as far from your chest as the sole of your foot.

• Why do men have nipples? Because we all start out as girls! Nipples show up in utero before sex organs do. And then they just stick around (and out).

GET HANDSY IN THE NAME OF HEALTH

Healthy breasts require regular at-home breast exams, but don’t let them stress you out. The goal here is to get a lay of the land and learn what all your lumps feel like. This way, if you develop something new or different, you’ll be the first to find it. Next to risk reduction, early detection ranks second as our best defense against cancer. I suggest starting a self-exam routine in your teens and doing one every month. Teenagers virtually never get breast cancer, but it helps them later to be familiar with their breasts now. Whatever your age, time exams to one week after your period since that’s when they’re the least lumpy, tender, and confusing. If you don’t menstruate anymore, make the first day of every month your exam day. The whole exam should take three minutes, and it may just be the most reassuring part of your day. If anything seems out of the ordinary, trust your intuition and see your doctor. Ready?

1. First, give your breasts a good stare. Disrobe from the waist up, stand in front of a mirror, and then scrutinize the breasts peering back at you. Visually scan them for shape, size, or contour changes, plus skin alterations like thickening, redness, dimpling, retraction, and bulging out. Your nipples should be pointing the way they always point—straight ahead, left, right, naturally inverted, or headed south checking for spare change on the floor.

2. Next, check to see if your breast tissue dimples or bulges out while watching your breasts in the mirror in two different positions. In the first posture, put your hands on your hips and push in so that you’re flexing your chest muscles. Any funny dents or bumps? In the second pose, raise both hands overhead like you’re getting arrested. All clear?

3. Exam time! Either reclining on your bed or standing in the shower—whatever is comfortable for you—put a little lotion or shower gel on your fingers to help them glide across the breast tissue. Pick one of the following four patterns to trace over your breast tissue: (1) up and down the length of the breast vertically, (2) left to right across the breast like words on a page, (3) concentrically in circles like a target sign, or (4) radially like spokes on a wheel. Whatever pattern you choose, the results will be the same—just be sure to use the same technique every month so your fingers develop an unconscious memory of the tissue.

4. Start with your left breast, and raise that left arm behind your head to flatten the tissue as much as you can (I know—some breasts are way too floppy to flatten). Use the fat pads of the three middle fingers on your right hand to do the exam. You’re feeling for a new lump or thickening. Start in your armpit, then transition to the upper outer part of your breast and make tiny circles gliding across the breast until you’ve evaluated the entire breast in whatever pattern you chose from number 3 above. Don’t ever lift your fingers off your breast skin as you do this. Repeat the entire exam three times—first with a light touch, then medium, then deeper still.

5. Gently squeeze your...
