Radiation therapy is commonly used in prostate cancer treatment. It may be used instead of surgery or after surgery in early-stage prostate cancer (adjuvant radiotherapy). Radiation treatments also can be combined with hormonal therapy for intermediate risk disease, when surgery or radiation therapy alone is less likely to cure the cancer.
In males, researchers suggest that the overall reduction in cancer death rates is due in large part to a reduction in tobacco use over the last half century, estimating that the reduction in lung cancer caused by tobacco smoking accounts for about 40% of the overall reduction in cancer death rates in men and is responsible for preventing at least 146,000 lung cancer deaths in men during the ...
The radiation does not affect the back passage (rectum, blue) at all. When LDR prostate brachytherapy (seed or polymer source implantation) is carried out, an ultrasound probe is inserted into the rectum (back passage), and images from this probe are used to assess the size and shape of the prostate gland. This is done so that the doctor can ...
Annual estimates of life expectancy are provided by the World Health Organization. [3] According to the WHO, healthy life expectancy (HALE) in Russia in 2019 was 64.2 years: 60.7 for men and 67.5 for women. [4] Also according to the WHO, Russia, Ukraine and Belarus exhibit the world's highest difference in life expectancy between women and men. [3]
1940. Overall life expectancy: 62.9 Women: 65.2 Men: 60.8 The United States began the ’40s on an upswing, with life expectancy up sharply from 58.5 years in 1936, when the nation was still ...
The life expectancy in some states has fallen in recent years; for example, Maine's life expectancy in 2010 was 79.1 years, and in 2018 it was 78.7 years. The Washington Post noted in November 2018 that overall life expectancy in the United States was declining although in 2018 life expectancy had a slight increase of 0.1 and bringing it to ...

The therapeutic effect of all three types is based on local deposition of radiation dose by high-energy beta particles. All three types of microsphere are permanent implants and stay in the tissue even after radioactivity has decayed. 90 Y, a pure beta emitter, has half-life 2.6 days, or 64.1 hours.
