According to the latest statistics, one in eight women will develop breast cancer in her lifetime. Luckily with new advancements in treatment, the mortality associated with breast cancer has decreased. Still the disease claims over 40,000 lives a year in the US alone, so knowing how to reduce your risk of breast cancer is an important asset.

What Causes Breast Cancer?

Breast cancer is the result of DNA mutations, which is characterized by a solid tumor that originates in the tissue of the breast. There are a few different factors that can cause this DNA mutation. The majority of them are acquired later in life. The most common age of diagnosis is 65. Age is the main risk factor for breast cancer simply because the longer you live, the more opportunity there is for the DNA in your breast to develop a mutation.

Sometimes these DNA mutations are inherited at birth, like the BRCA1 or BCRA2 gene. If your family has a history of breast cancer, it is important to go through screening and genetic treatment early, as sometimes preventative treatment is recommended. (NY Daily News)

Your breast cancer risk is also tied to certain other health issues, which is where our 9 ways to reduce your risk come in. Some recent studies have found that there are in fact some changes you can make and habits you can work on to reduce your odds of getting breast cancer:

  1. Be mindful of your weight. Becoming overweight or obese (especially after menopause or later in life) increases breast cancer risk. This is because after menopause, most of your estrogen comes from fat tissue. Having more fat tissue increases your chance of getting breast cancer by raising estrogen levels. Women who are overweight also tend to have higher levels of insulin, which is another hormone. Higher insulin levels have also been linked to other cancers.
  2. Exercise regularly. A few different studies have found that exercising regularly can improve your chances of avoiding breast cancer. One particular study from the Women’s Health Initiative found that as little as 1.25 to 2.5 hours of brisk walking per week reduced a woman’s risk by 18%. The American Cancer Society recommends that you don’t try to cram this into one long workout, but instead spread it out over the course of the week.
  3. Limit time spent sitting. A study from the American Cancer Society showed that women who spent more than 6 hours a day sitting when not working had a 10% greater risk for invasive breast cancer compared with women who sat less than 3 hours a day.
  4. Limit your drinking. Research has shown that women who have 2 to 3 alcoholic drinks a day have about a 20% higher risk compared to women who don’t drink at all. Women who have one drink a day have a very small increase in risk as well. Excessive drinking has been found to increase your risk of other cancer types as well. (American Cancer Society)
  5. Don’t smoke. It’s no surprise that smoking is bad for your health. However, accumulating evidence suggests that there’s actually a link between smoking and breast cancer risk, particularly in premenopausal women.
  6. Breastfeed. According to the Mayo Clinic, breast-feeding may play a role in breast cancer prevention. They suggest that the longer you breastfeed, the greater the protective effect. (Mayo Clinic)
  7. Avoid or limit hormone replacement therapy. Hormone replacement therapy (or HRT) was used in the past to help control some symptoms of menopause like night sweats and hot flashes. Researchers now know that postmenopausal women who take the combination of estrogen and progestin may be more likely to develop breast cancer. Breast cancer risk appears to return to normal within five years after stopping this treatment. (American Cancer Society).
So instead, talk to your doctor about other options to control your menopause symptoms. If you do decide that HRT is the right choice for you, it’s best to use the lowest dose you can for the shortest possible time.
  1. Avoid exposure to radiation and environmental pollution. While environmental pollution can be difficult to protect yourself against, there are steps you can take to reduce your exposure to radiation. Medical-imaging methods, such as computerized tomography, use high doses of radiation that may be linked with developing breast cancer. Reduce your exposure by having a conversation with your doctor to make sure every test is absolutely necessary before they’re done.
  2. Receive annual mammograms starting at age 40. Since most of the time breast cancer does not cause symptoms until the disease is quite advanced, it is important to detect it long before symptoms appear. For most women, starting at age 40 is early enough, but higher risk patients (like women with a mother or sister who had cancer at an early age) may need to start getting mammograms much earlier.

Understanding the Mammogram Procedure

Posted on
by Oncologic Advisors

Approximately 252,710 American women will be diagnosed with invasive breast cancer in 2017. Breast cancer is the second deadliest form of cancer in women, and of those who are diagnosed around 40,610 are predicted to die. The good news is that early detection radically increases a woman’s chances of survival, and advanced screening techniques (including the mammogram procedure) combined with new, personalized therapies are creating stronger, more effective ways for doctors and their patients to fight the disease ([1] American Cancer Society).

You probably know that the mammogram procedure is one of the most common ways that doctors screen patients for breast cancer. But how do you know if you should get one? And what should you expect if you’ve never had a mammogram procedure before?

Don’t let fear of the unknown prevent you from utilizing this potentially-lifesaving measure. Here we’ll demystify some important facts about mammograms, and talk through what you need to know about standard mammogram procedure before you get one.

SHOULD I GET A MAMMOGRAM?

A mammogram is an X-ray of the breast that is used to screen for and diagnose cancers and other breast diseases that may not be visible from the outside or detectable by touch (Johns Hopkins).

Women over 40, women with a personal or family history of breast cancer, and women who have tested positive for certain genetic markers associated with an increased risk for the disease appear to derive the greatest benefit from mammograms. Age is an important factor in determining when a woman should begin to use mammograms as a method of screening: younger women tend to have a lower incidence of breast cancer, and tend to have denser breast tissue that makes mammography less reliable as a preventative strategy.(UpToDate).

You and your doctor must work together to determine if mammograms are an appropriate screening strategy for you. Your doctor may order a mammogram as part of a regular, precautionary regimen (a “screening mammogram”), or if a lump or other anomaly is discovered during a previous mammogram or breast exam (a “diagnostic mammogram”). If so, your doctor will refer you to a radiology facility or clinic that is equipped to perform the procedure. You may also get a referral for a mammogram through Planned Parenthood (Planned Parenthood).

Mammograms are often an outpatient procedure, though your doctor may also order one as part of your treatment while you are in the hospital (Johns Hopkins). Your doctor may recommend mammograms in combination with other screening and diagnostic methods such as clinical breast exams (palpation or examination by touch), ultrasound or MRI imaging, and genetic testing. Modern techniques mean the radiation exposure a woman receives from a mammogram is considered to be negligible (UpToDate).

MAMMOGRAM PROCEDURE: WHAT TO EXPECT

Mammogram procedure may vary slightly from facility to facility, and from woman to woman. That said, there are several basic steps that you should take in order to prepare for your mammogram no matter where you go.

If you are visiting a mammogram facility for the first time, always bring your medical records with you or arrange to have them delivered to the clinic. ([2] American Cancer Society). Always inform the facility if you’ve had any kind of medical procedure performed on your breasts in the past, including previous mammograms, biopsies, breast implants, enhancements, or breast reductions. Always inform your technician in advance if you have breast implants, if you are pregnant, or if you are currently breastfeeding. Women with implants can (and should) still receive mammograms, though your facility may need to take extra measures to in order to ensure the most accurate results. Silicone or saline implants will obscure part of the breast tissue that is visible on a mammogram, and so additional imaging is typically required for women who have them. ([3] American Cancer Society). You may need to arrange for a technician or facility experienced in screening women with implants, so don’t be afraid to ask questions when you make your initial appointment (Johns Hopkins).

Be sure to remove any nipple piercings or jewelry on or near your breasts prior to your visit. Don’t wear antiperspirant, deodorant, skin creams, or powders on or near your breasts the day of your mammogram: many of these products contain metallic substances (like aluminum) which may appear on the mammogram as a white spot or calcification (Johns Hopkins).

When you arrive, your technician (also called a radiologic technologist) will talk you through the details of the mammogram procedure. Be sure to mention any lumps, changes, or unusual symptoms you may have noticed at this time, in addition to any hormonal treatments you may be taking or changes (like menopause) you may be experiencing.

Before your mammogram, your technician will ask you to remove your bra and clothing from the waist up and provide you with a gown. The technician will then have you stand in front of a mammography machine, which compresses each breast between two plates in order to take an X-ray picture. “Flattening” the breast in this way allows your technician to obtain a more accurate image, and also reduces the amount of radiation required for the procedure. This compression may be uncomfortable, but it shouldn’t be painful; scar tissue or recent surgery may cause greater discomfort for some women, and many women find it helpful to avoid scheduling their mammograms immediately prior to or during menstruation when breasts are more likely to be tender. (Johns Hopkins). Don’t be afraid to speak up and tell your technician right away if something is painful!

Your technician will scan each breast one at a time, repositioning the breast on the X-ray plate between each image. Typically, he or she will take two images per breast for women without implants, and four images per breast for women with implants, though the exact number of images may vary from woman to woman ([3] American Cancer Society).

All in all, the whole procedure should take 20-30 minutes. (Johns Hopkins)

WHAT NEXT?

After a radiologist has read and analyzed the X-ray films, the mammography clinic will send the results to the doctor who referred you. The clinic will also mail a summary of these results directly to you ([2] American Cancer Society). You may be asked to go back in for additional imaging after your initial mammogram. Remember that getting called back is quite common, and does not necessarily mean you have cancer. As the American Cancer Society notes, “less than 10% of women called back for more tests are found to have breast cancer.” ([4] American Cancer Society).

You may have heard about instances of “false positive” results from mammograms, or read about the risk of  “overdiagnosis” and “overtreatment” associated with mammograms as a method of screening: that is, sometimes a mammogram may detect a lump or other disease that would typically be benign if it went undetected, leading to unnecessary treatment. The good news is that more specific, “personalized” screening measures – like using genomic testing to determine if a woman is at increased risk for breast cancer, and thusly more likely to benefit from mammograms – are helping doctors to reduce the incidence of false positives, keep costs down, and make the best possible use of mammograms as a screening and diagnostic tool (STAT).

Remember that it is often difficult to tell how aggressive a cancer or other disease may be through mammography alone, so always talk to your doctor about your options for further testing and treatment if your mammogram does come back with abnormal results. Don’t be afraid to ask questions if you have trouble understanding something, or to get a second opinion if you have any doubts or concerns about your results or treatment.

Above all, remember that mammograms are just one of the many resources women have at their disposal to make better, more informed choices about their health. And in the fight against cancer, a little knowledge can be a lifesaving thing.
