Mammography reduces death from breast cancer by up to 30%

Study published in the journal Radiology finds that mammography, in fact, significantly reduces mortality from breast cancer. In the follow-up, 133,065 women were randomly divided into two groups - one who only did the mammographic screening, and the first two mammographic screening tests. examination and others who received the usual medical care. At the end of the study, there were 30% fewer deaths from this type of cancer among women who had a mammogram. Women between the ages of 40 and 49 were examined on average every 24 months, and women aged 50-74 were tested on average every 33 months. This phase of testing lasted approximately seven years.

For the current study, almost three decades after the start of the first tests, the researchers analyzed the original data and follow-up data to estimate the long-term effect of mammography on the mammogram. mortality from breast cancer.

The analysis of death cases at follow-up showed a reduction in mortality from breast cancer similar to the first studies. The absolute benefits related to saved lives grew over time: in the 29 years of study, the estimated number of women who passed the examination every two or three years over a seven year period and whose deaths were avoided thanks to it was 414 to 519.

According to the researchers, the assessment of the actual impact of mammography requires follow-up of 15 to 20 years because the number of deaths from breast cancer prevented increases over time. They further state that most avoided deaths occur more than 10 years after the start of screening, indicating that the long-term benefits are more than twice those seen in the short-term. Every 1,000 to 1,500 mammograms, one death from breast cancer is prevented.

Prevent

The second leading cause of death among women, breast cancer, can be diagnosed and treated early, which greatly increases the chances of survival of the patients. Women can and should be actively involved in this detection by conducting regular mammograms and clinical breast exams and even by daily and / or monthly self-examination.

It should be remembered that a monthly self-examination does not replace screening mammography or clinical breast exams performed by a health care professional in women over the age of forty.

A screening mammogram is the best tool available to detect early breast cancer even before the onset of symptoms. Studies have shown that screening mammography decreases the risk of death from breast cancer.

Taking many medicines at the same time raises the risk of erectile dysfunction

According to a study published in the British Journal of Urology International, the use of many medications at the same time is associated with an increased risk of erectile dysfunction (ED). The survey looked at 37,712 men of various ethnicities in Southern California, United States, and is part of the California Men's Health Study, which encompasses men ages 46 to 69.
