November 12, 2018 16:33

The medical world is an ongoing debate about the extent to which regular diagnostikana breast cancer actually improves a person's chances of survival. New study tries to solve this debate.

Breast cancer is the most common type of cancer diagnosed in women, and the National Cancer Institute estimates that by the end of 2018 266,120 new cases will be diagnosed in the United States.

For information on how to carry out the treatment of breast cancer in Israel, the best specialists of the country, leave a request and we will contact you shortly.

According to the World Health Organization (WHO), more than 508 000 women died in 2011 alone due to causes related to breast cancer.

However, most forms of breast cancer are highly treatable, and usually the assumption is that the sooner he will be diagnosed, the more effective the treatment will be.

Recently, experts of Queen Mary, University of London in the United Kingdom, Falun Central Hospital in Sweden and many other research institutions around the world have decided to establish the importance of screening for breast cancer in order to improve survival after diagnosis.

The study, which took into account the health information of more than 50 000 women, it was found that breast screening is very useful. Research paper is now available in Cancer, the journal of the American Cancer Society (ACS).

60 percent risk of death

In his study, a team of scientists analyzed data collected from 52,438 women aged 40 to 69 years. Some of these participants were screened for breast cancer within a 39-year period in 1977-2015 years in Dalarna, Sweden.

To improve the assessment of how to organize the initiative of screening on breast affect health outcomes, experts who conducted a recent study used a new method, which includes the calculation of the annual incidence of breast cancer leading to death within 10 years and over 20 years after diagnosis.

The researchers found that women who have joined the organized screening program for breast cancer had a 60 percent risk of death within 10 years after the diagnosis of cancer. They also had 47 percent risk of death within 20 years after diagnosis of breast cancer.

All participants who have been diagnosed with breast cancer, the investigators point out, have received appropriate treatment at the stage of the cancer, they experienced, according to the latest national guidelines at the time.

The researchers suggest that screening allows specialists to detect cancers at an early stage, which means that the tumor can be treated before, and they are the best response to therapy.

"Recent improvements in treatment have led to a reduction in mortality from breast cancer," - says senior study author Professor Stephen Duffy of Queen Mary University of London.

"However, these new results demonstrate the vital role played by the screening that gives women a much greater benefit from current treatments. We must ensure that participation in breast screening programs has improved, especially in the socio-economically disadvantaged areas. "

"Our results - the exact data on an individual basis, spanning 6 decades, the need to provide women and their physicians confidence that participation in a regular high-quality mammography - the best way to reduce the risk of premature death from breast cancer," the study authors conclude in the published article .
