According to the CDC (the centers for disease control and prevention) some of the most common cancers among men are – prostate, lung and the colorectal cancers. Prostate cancer is also the second common cause of death among white, African American, American Indian/Alaska Native and Hispanic men, and the fourth most common cause of death from cancer among Asian/Pacific Islander men. It is the most common malignant cancer with the increased incidence over the last decade. About 1 in 7 men are diagnosed with prostate cancer in their lifetimes. It is a form of cancer that forms in the tissues of the prostate (a gland in the male reproductive system that lies below the bladder and in front of the rectum). It is more likely to occur in older men but can concurrently occur at any age. An estimated new cases and deaths from prostate cancer in the United States in 2014 is about 233,000 and 29,480 respectively. However, cancer is slowly but surely becoming more common in the elderly because of the increase in life expectancy. It usually is a very slow growing cancer, often causing no symptoms until it is in an advanced age. Most of the men with prostate cancer die because of other reasons and many do not even know if they have the disease. But the cancer becomes dangerous once it begins to grow and spread outside the prostate. Risk Factors for Prostate Cancer About 80% of men who fall captive to prostate cancer are 65+ years of age. Fortunately about 85% of the American men with prostate cancer are diagnosed during early stages thus leading to good prognosis since at an early stage it can be treated and chances of survival are very high. But in the cases where it spreads beyond the prostrate viz. bones, lymph nodes or lungs, it becomes incurable. Some of the risk factors for the disease in the elderly are: - Age: The older a man is, the greater his risk for getting prostate cancer. - Family history and genetics: Genes that people inherit from their parents can be a risk factor for the disease. Currently there is no single gene that can surely raise or lower the risk of getting prostate cancer. But if someone has his father, brother or son with prostate cancer then it is two or three times more likely for him to develop the disease as well. Experts estimate that the hereditary form of prostate cancer accounts for just 5% to 10% of all cases. - Race: Prostate cancer is more common in some racial and ethnic groups as compared to others. Although the medical experts do not have any explanation for that as of now. - Diet: Researchers suggest that high dietary fat is also one of the factors responsible for prostate cancer. The disease is much more common in countries where meat and dairy products are dietary staples compared to countries where the basic diet consists of rice, soybean products and vegetables. - Not exercising also makes prostate cancer more likely to happen to anyone. Although prostate cancer can be a serious and a debilitating disease but most men who have it cancer do not die from it. More than 2.5 million men in the United States who have been diagnosed with cancer are still alive today. Even though it is one of the most common cancers to occur in men, the modern radical prostatectomy techniques are associated to deal with it have a rather low perioperative morbidity and thus excellent clinical outcomes.

PROSTAT KANSERİNE NEDEN OLABİLEN RİSK FAKTÖRLERİ NELERDİR ? Farklı kanserlerin farklı risk faktörleri vardır. Araştırmacılar, bir erkeğin prostat kanserine yakalanma riskini etkileyebilecek çeşitli faktörler bulmuşlardır. Yaş Prostat kanseri 40 yaşından genç erkeklerde nadir olmakla birlikte, prostat kanseri olma olasılığı 50 yaş sonra hızla yükselir. Prostat kanserli 10 olgunun yaklaşık 6’sı, 65 yaşından büyüktür. Irk Prostat kanseri özellikle Amerika’da yaşayan siyah derili erkeklerde sık gözükmektedir. Ülkemizde erkeklerde prostat kanseri daha az sıklıkta görülür. Bu ırk ve etnik farklılıkların nedenleri kesin olarak bilinmemektedir. Coğrafya Prostat kanseri Kuzey Amerika, kuzeybatı Avrupa, Avustralya ve Karayip adalarında yaygındır. Asya, Afrika, Orta Amerika ve Güney Amerika'da daha az sıklıkta görülür. Bunun nedenleri kesin olarak bilinmemektedir. Aile Öyküsü Ailesinde (baba, erkek kardeş vb.) prostat kanseri bulunan erkeklerin prostat kanserine yakalanma olasılığı, diğer erkeklere (ailesinde prostat kanseri olmayan) göre daha yüksektir, Fakat çoğu prostat kanseri ailesinde herhangi bir prostat kanseri olmayan erkeklerde gözükmektedir. Kişinin babasında veya bir erkek kardeşinde prostat kanseri olması, bir erkeğin bu hastalığa yakalanma riskini iki kat artırır (Özellikle erkek kardeşinde prostat kanseri olanlarda bu risk daha fazladır). Eğer kişinin birden çok yakını genç yaşta prostat kanseri olmuş ise o kişinin prostat kanser olma ihtimali çok yüksektir.
