Study: Aggressive breast cancers more likely to hit black and younger women

Study: Aggressive breast cancers more likely to hit black and younger women These cancers are also less responsive to treatment, researchers said.

Black and white women get breast cancer at roughly the same rate, but black women are more likely to die from it. The key question researchers are still trying to answer is: Why? “ Likely a person’s own biology along with factors such as physical activity and sedentary behavior play a role

A new study by the American Cancer Society revealed both good and bad news about breast cancer in America. Although deaths from breast cancer continue to fall, they're declining at a slower rate than in previous years and the number of cases we're seeing is on the rise. The research also found that black women are significantly more likely to die from breast cancer than white women.

"Well, first of all, 40% decrease [in deaths] over the last three decades in breast cancer — that's great news. The problem is, women are still dying of this horrible disease," CBS News medical contributor and cancer expert Dr. David Agus told "CBS This Morning."

Breast cancer risk reduced by swapping red meat for poultry, study finds

Breast cancer risk reduced by swapping red meat for poultry, study finds Heads up, ladies: Consider swapping chicken for red meat the next time you have the choice, as doing so may reduce the risk of breast cancer, a new study suggests. © Provided by Fox News Network LLC The study, published in the International Journal of Cancer, followed the “meat and meat cooking practices” of more than 42,000 women for an average of roughly eight years. By the end, researchers women who ate the most amount of red meat had an estimated 23 percent higher risk of developing breast cancer than those who ate the least amount of red meat.

Even though black and white women have similar mammogram screening rates and black women have a lower overall incidence of breast cancer , black women are more likely to die from the disease. In explaining the disparity, one oncologist described a "perfect storm" of scientific and social

Compared with white women , black women had lower rates of getting breast cancer (incidence rates) and higher rates of dying from breast cancer (death rates) between 1999 and 2013. Breast cancer was more likely to be found at an earlier stage among white women than among black women .

One in eight women will be diagnosed with breast cancer in her lifetime and more than 3.8 million women living in the U.S. have a history of breast cancer.

Part of the rise in cases, according to Agus, can be attributed to obesity rates and the fact that more women have not had children.

"So being large or obese increases the rate of breast cancer, as does not having children," he said. "The actual reason — we don't know. Hormone levels are different because of both of them. Somehow the hormonal milieu of us, one portends for more breast cancer, one portends for less. These are important observations. Obviously as our norms in the country change, we're seeing that increase."

Scientists Turn Breast Cancer Cells Into Fat, Stops Disease From Spreading, Report Says

Scientists Turn Breast Cancer Cells Into Fat, Stops Disease From Spreading, Report Says Their research found that treating the test subjects with a diabetic drug (rosiglitazone) and a cancer treatment (trametinib) triggered the amazing cell change.

Breast cancer is actually less common in black women than white women . However, black women are more likely to be diagnosed with triple-negative It can also manifest in feelings of fear or distrust when you have to travel far from your neighborhood for treatment, said Gehlert, not to mention the

The U.S. has a problem with maternal mortality, especially for women of color. Black infants are more than twice as likely to die as white infants; black

But we are getting better at treating the disease, which has translated to far fewer deaths. Treatment options have also advanced dramatically over the last decade.

"We have the ability to target molecules or switches within the breast cancer, and I think importantly we can block the 'don't eat me signal' on the cancer, allowing your own immune system to attack the cancer. So chemotherapy has gotten better, together with molecularly targeted therapy and immunotherapy. There is real hope for continuing to lower the death rate," Agus said.

While early detection remains key in surviving the disease, Agus also points to advancements in genetic testing and recommends everyone get tested for the BRCA gene, a mutation that means you have a much higher risk of developing breast cancer. The tests, once thousands of dollars, are now far more affordable.

"To me, knowledge is power. Man or woman should have this test. You should know if you're at risk for this breast cancer, ovarian cancer, other cancers associated with these genes, and also whether your children or parents are at risk. Knowledge to me is really key to knowing what to do," he said.

The research also found that race plays a major factor in surviving breast cancer. Black women are seven times more likely to die from the disease than white women.

Agus said part of the reason may be that black women, on average, tend to have a higher body mass index, and obesity correlates with a higher breast cancer death rate. "And in addition, the biology may be different," he said.

But unequal access to care might be the key.

"The interesting thing is in the state of Massachusetts, where there's care for everybody, the death rates are similar between white women and black women. So I think there's a lesson there that we have to increase access to care so we all get these remarkable advances that have happened in the treatment of breast cancer."

This is the Amount of Alcohol That Increases Breast Cancer Risk .
When it comes to breast cancer prevention, drinking less alcohol and exercising more may help. Alcohol has long been linked to a higher risk of breast cancer, but how much is enough to make a difference? It seems even a moderate intake—drinking one glass of wine, beer, or any other type of alcohol a day—may raise your risk of breast cancer, according to the American Institute for Cancer Research (AICR) and the World Cancer Research Fund.
