It’s easy to forget how common breast cancer is.
The disease has overtaken the lung as the leading cause of cancer death worldwide.
Yet in many cases, there’s nothing that you can do to stop the disease.
Breast cancer is so rare and difficult to detect that it often goes undiagnosed.
Even if you do have the disease, there are no treatments, tests or cures.
The only way to know that you have it is through your symptoms.
In a new study published in The Lancet, researchers at Harvard Medical School found that people who have breast cancer have an easier time getting tested for it, which is why they are more likely to develop the disease and die.
“It’s a very rare disease,” said study co-author Dr. John K. Leung, the director of the Harvard Cancer Center.
“We have the world’s best screening technology and we can identify people early enough to make a difference.”
The team used data from the World Health Organization’s National Breast Screening Program to track about 2.5 million cases of breast cancer.
The researchers compared the screening data with the cancer death rate in the United States.
In other words, what’s more likely?
The answer: People who have more breast cancer in their family, or those who have had more tests.
The results showed that people with a family history of breast cancers were more likely than those without.
That’s because a lot of people with breast cancer don’t have any tests for the disease yet, so they may be less likely to test.
The same holds true for people who had more than one breast cancer, which could mean they have a higher risk of developing cancer in the future.
It’s the same for people with more than three tumors.
And the data also showed that the more tests a person had, the more likely they were to have cancer in future.
The most common risk factor for breast cancer was the presence of a genetic mutation, and people who were also women had a higher chance of developing the disease than men.
Researchers found that the risk of cancer for women was higher than that for men, but they found no relationship between the two.
In fact, the only time a genetic risk was significantly higher in women was among those with the mutation.
“This is really exciting because it shows that there are many genes that are involved in breast cancer,” said Dr. Pauline K. Schumacher, a breast cancer researcher at Johns Hopkins University.
“The question is, why are women more likely, than men, to develop cancer?”
The study suggests that breast cancer screening should be done before menopause.
Women have more than twice the risk for breast tumors in their lifetime than men do, and the increased risk is highest among women who are older than 60, who tend to have a more advanced cancer.
However, screening before menopausal age has been shown to be a strong preventive strategy, and studies have shown that women are less likely than men to develop breast cancer if they don’t get screened at all.
But there’s a problem: the World Cancer Research Fund said it was too soon to say whether screening before age 60 will be a preventive strategy.
So the researchers used data on the National Breast and Cervical Cancer Screening Project to look at whether screening is an effective strategy to reduce breast cancer deaths.
The data showed that, for women, the risk reduction was significantly lower when screened early.
But in men, screening early was not enough.
“There’s a lot we still don’t know about this disease,” K.M. Schubert, a senior scientist at the National Cancer Institute, said.
“It’s been a long time since we’ve had good evidence about breast cancer survival.”
The study also looked at the age at which women and men are diagnosed with the disease; men were more than four times more likely at the time they started the study.
“If we want to reduce deaths, we need to stop screening at any age,” Kieke M.M., the lead author of the study, said in a statement.
“In a few years, we’ll know whether or not it’s the case that there is a biological or genetic risk that’s associated with breast cancers.
In the meantime, the goal is to prevent death, which will require early detection and early intervention.”
The research team is now looking at ways to test for cancer in more people.
For example, screening women and getting them tested at their homes and in the community could help prevent cancer and save lives.
But the new study suggests more research needs to be done to understand why certain genes are associated with increased risk.
For now, the team is focusing on screening older women who have a mutation that could affect their ability to detect breast cancer and how to better understand how this mutation affects cancer risk in women.
