October is Breast Cancer Awareness Month, which is an annual campaign to increase awareness of the disease.
Women urged to become ‘breast dense’ aware following release of new research
Dense breasts is linked to a significant increased risk of breast cancer yet a new national survey shows more than three quarters of women, 78 per cent, don’t know if they’re among the two million women with the known risk factor.
The survey, commissioned by health organisation Pink Hope, also shows two-thirds of women had no idea density can obscure a lesion or lump on a mammogram.
Professor Mary Theresa Rickard, Chief Radiologist at Sydney Breast Clinic says the risks associated with density fall second only to those due to known gene mutations.
Women cannot tell if they have dense breast by the look or feel, it’s only the mammogram that can show the density, Prof Rickard said.
“When we talk about density we talk about how white is the breast on the mammogram. The whiter the mammogram the greater your risk of getting breast cancer,” explained Prof Rickard.
“Our chances of finding a cancer on a dense breast are not as good as they are on finding it on a fatty breast, so greater chance that your cancer will be missed if you have a dense breast,” Prof Rickard said.
The radiologist says women need to be their “best breast advocate” and ask the question at their next mammogram.
“If you know that your density is high then you can make sure that your breast cancer screening is personalised and tailored to your risk,” said Prof Rickard.
It’s something cancer advocate Connie Johnson campaigned for heavily during the last few years of her life — she died earlier this month after a lifelong battle with cancer — urging women to get their breasts checked.
Currently, women everywhere, except in Western Australia, have to ask the radiologist at the time of a mammogram if they have dense breasts, says Cancer Council Australia CEO Professor Sanchia Arnada.
“There’s a bit controversy in Australia at the moment whether BreastScreen should provide that information to women, currently they do only in WA and not in the other programs and partly this is because we don’t actually know what the evidence-based advice would be,” Prof Aranda said.
Because of this, Pink Hope is calling on the federal government to better-equip the healthcare community with the necessary tools, information and guidelines to ensure a unified and consistent approach to breast density diagnosis and treatment.
“We know that women are being referred to their GP, but that GPs — as a result of Australia’s lack of consistency on breast density — currently lack the established guidelines on breast density needed to best-support them,” Kyrstal Barter, Pink Hope CEO said.
“In many states in America, women during a mammogram, they have to by law be told they have dense breast tissue, there are systems in place overseas and they may not be exactly what we need here but at least they are doing something proactive,” said Ms Barter.
6 Surprising Things That May Improve Breast Cancer Treatment
Here are some strategies recommended by experts—and others that are still being explored—which may help improve the effectiveness and symptoms of treatment.
Physical activity
“Exercise is one of the best things women can do for themselves,” says Dr. Ann Partridge, director of the Program for Young Women with Breast Cancer at Dana-Farber Cancer Institute . “It doesn’t mean marathons or hot yoga, but walking three to five times a week can make a huge difference it terms of energy, stamina and how you feel during treatment.” Partridge says that while exercising during treatment won't be easy for every woman with breast cancer, it can be worthwhile if there days during treatment cycles where women feel up to it.
The benefits extend not just to the body, but also to the brain. A new pilot study of 87 breast cancer survivors found that women who did a 12-week exercise program more than doubled how fast they were able to take in information, as measured by cognitive tests, compared to women who weren't in the exercise group and who just received emails about health topics.
Moving more is good preventative medicine, too. Several studies have found that physical activity can lower a woman’s risk for breast cancer, and some studies found that the most active women have about a 25% lower chance of developing the disease than the least active women. A 2015 study found that the more fit women were, the lower their risk for developing the disease.
“The exercise guidelines were developed with [heart disease] outcomes in mind,” said study author Christine Friedenreich, scientific leader of cancer epidemiology and prevention research at Alberta Health Services, in 2015. “So at that level, they can have an effect on blood pressure, cholesterol levels and waist circumference. But for cancer prevention, we may need to exercise at higher volumes.”
Healthy eating
A diet high in fruits and vegetables has been linked to a lower risk of breast cancer. Studies have shown that following a mostly plant-based diet can reduce risk of developing breast cancer (by about 15%, according to one). When researchers in a 2016 study asked a large group of women what they had eaten as teenagers, they found that those who reported eating about three servings of fruit a day as teens had a 25% lower risk of developing breast cancer than those who ate less.
Eating well throughout treatment is also helpful, says Partridge. “I don’t mean you have to start juicing or eating organic, but take care of your temple,” she says. “Don’t overdo it with carbs or comfort foods.”
Yoga
Up to 80% of women with breast cancer in North America use complementary or integrative therapies, and one of the most studied is yoga. Researchers have found that practicing yoga has a host of health perks, including lowering a person's risk for heart disease, type 2 diabetes, depression and hypertension. There's also evidence that yoga may help the side effects of cancer treatment. In one 2017 study, doing yoga twice a week improved the levels of fatigue and quality of life for men being going through radiation treatments for prostate cancer.
It may also help people recover after cancer treatment. A study from researchers at Ohio State University looked at 200 breast cancer survivors who had completed treatment in the last three years and were either assigned to 12 weeks of yoga classes or no yoga. The researchers found that the women who practiced yoga had lower fatigue and markers of inflammation than women who did not do yoga.
Sleep
Sleep is a critical part of good health, and experts recommend that adults get between seven to nine hours each night. Accumulating research also suggests that the amount of sleep a woman gets is linked to better survival from breast cancer. In a 2016 study researchers found that women who slept less than five hours a night on average before they were diagnosed with breast cancer were nearly 1.5 times more likely to die from their breast cancer than women who reported sleeping seven to eight hours. The study only found an association between more sleep and greater survival, but the poor health outcomes related to insufficient sleep are well established.
Treatment timing
Research is still in the very early stages. But in 2014, researchers at the Weizmann Institute of Science in Israel found evidence in mice suggesting that cancer treatment might be more effective in the evening, thanks to certain bodily processes that happen at night. In a study published in the journal Nature Communications, they reported that a mouse’s daytime production of steroid hormones in the body hindered the effects of certain receptors that are targeted by cancer drugs. Since the study was in mice, scientists don’t know yet whether nighttime therapy works better in humans, but it’s not the first study to suggest that the body may be receptive to treatment at night.
Meditation
“Beyond taking care of your body, it is also important to take good care of your mind,” says Partridge of Dana-Farber Cancer Institute . “When you are emotionally not doing well, you feel things more physically.” Partridge says that when people feel tired, stressed or upset, they may perceive their physical symptoms of cancer as worse.Partridge recommends adopting practices like mindfulness meditation. A 2014 review of available research found that meditation is effective when it comes to treating symptoms of mood disorders that are common among women with a recent breast cancer diagnosis.
