You can find prostate cancer news all over the internet. I have been searching for the latest prostate cancer news and this is what I found out. "Thanks to the blood test PSA (prostate specific antigen), for 23 years we can diagnose early stage prostate cancer," explained Martin Sanda, professor at the Faculty of medicine of Harvard University, lead author of the study.

PSA (prostate specific antigen) is a protein produced by prostate and its level increases when the prostate is increased or when there is cancer. "This test allows the detection of small tumors in the prostate, which are not dangerous in the short or long term," added Martin Sanda. The test allows doctors to offer much earlier treatment and with a higher success rate instead of those various aggressive treatment of prostate cancer cases.

The authors analyzed the findings of an extensive study provided data on 51,529 men who participated, who were monitored since 1986. Of these, 3331 were diagnosed with cancer during 1986 to 2007. Furthermore, the study revealed that 342 of the volunteers diagnosed with cancer, representing about 10%, have decided to delay starting treatment with at least one year.

At 10 years of diagnosis, half of the volunteers who have decided to wait, have not yet started any treatment. The study authors analyzed medical data for all patients, eight years after diagnosis, and comparisons were made between those who opted for aggressive treatment (surgery, radiotherapy or hormonal therapy) and those who have decided to delay their treatment.

"We found that the mortality rate was very low among men suffering from prostate cancer of small risk," said Martin Sanda. Analysis showed that only 2% of men suffering from this form of cancer of the prostate and the delayed start of treatment had died, compared with 1% of patients suffering from a similar form of cancer that started treatment early, the researchers explained American, which indicated that such differences are unimportant in terms of statistics.

According to this study, most men diagnosed with low risk prostate cancer who deferred to start with, on average, eight years - or even 20 years - still feel good. They thus avoided and frequent inconvenience caused by cancer treatments. According to experts, there are three types of cancer prostate cancer with large tumors, which grow at a rapid pace, medium-sized cancer tumors, small tumor cancer that develops slowly.

According to another study, published in the Journal of the National Cancer Institute, PSA test led to a "supra diagnosis" of prostate cancer in the past 23 years. After the launch of this test on the market, in 1986, about 1.3 million men were diagnosed with prostate cancer; these are cases which were not previously detected. Of these, one million were treated for cancer and suffered "unnecessarily inconvenience this treatment - the financial consequences and the anguish caused by this experience," explained the authors. After 1986, the number of men diagnosed with prostate cancer has tripled among patients aged 50 and 59 years and increased over seven times in patients who have not yet reached 50 years.
