Every male is at a potential risk in contracting prostate cancer. It is said that about one in six men will develop prostate cancer in his lifespan though only one in thirty-six of them result in dying from the disease. For men who approach the age of 80, about 80 percent of them have cancer cells in their prostate. The purpose of prostate cancer screening is to detect cancer in the early stages. If you have the knowledge and awareness of the risk factors, it helps you to determine a suitable prostate screening appointment with your doctor. Who exactly could have these risks and why?
Ever heard of the saying that age is just a number? Unfortunately, age and numbers matter the most in determining a diagnose for prostate cancer. The greatest risk factor in this debilitating disease is the age. White men after the age of 50 whose family have no prostate cancer history and black men after the age of 40 who have a close relative with the disease are at greater risk. Two thirds of men at the age of 65 and older are diagnosed with prostate cancer. The cancer acts less aggressively the older the patient is, usually when they are above 70 years old.
Family history plays an important risk factor in the development of prostate cancer. If a man has a relative in the family who had prostate cancer, the risk is weighed to be quite high. The American Society submits that the risk to getting prostate cancer is more than twice if the man’s father or brother has the disease. There is more heightened risk for having a brother that has prostate cancer than a father who is afflicted with it. If there are numerous family members affected, the risk is even much bigger. It is recommended that screening be done at age 40 for such men. There are studies showing that prostate cancer has hereditary genes that increase the risk of prostate cancer. Only about 5 to 10 perecent make the heredity forming prostate cancer in all of the cases according to some experts.
Another risk factor is race, where African American men have 60 percent more chances of getting prostate cancer than white American men. The cancer tends to be more advanced when diagnosed too. For Japanese and African males who reside in their home country, prostate cancer is very much less prevalent. However, once they immirgate to the U.S, these statistics take a hike discernibly. Arican American males at the age of 40 make them the second group of men to be screened and tested. Diets that are high in fat, environmental issues, lack of contact with sun, heavy metal exposure like cadmium, infectious agents and smoking are probable causes according to the theories of some researchers. Until now, the variation in races are still not clearly understood.
Some studies propose that diet is an assigned factor for prostate cancer. Countries that have a high dietary fat consumption based on meat, dairy products are more commonly strickened with the disease compared to countries where rice, soybean products and vegetables make up the staple food. The growth of prostate cancer cells is aided by saturated fats which causes testosterone production to rise.
Over the years, what is learnt is that prostate cancer have several diseases wth various causes. Slow growing tumors and more threatening and incurable cancers both have different underlying causes. For example, smoking may be a factor for advanced prostate cancer but has not been known for low risk prostate cancer factor. Similarly, men who consume less vegetables, especially in the broccoli family face higher risk of of aggressive prostate cancer but not to low risk prostate cancer.
A measure of obesity, which is the body mass index is not considered a link to a diagnose of prostate cancer comprehensively. As a matter of fact, due to the dilution of PSA in a bigger blood quantity, men with obesity have substantially lower PSA levels than non-obese men. Tall height, lack of exercise, sedentary lifestyle, high calcium intake, African American race and Agent Orange exposure are some examples of other aggressive risk factors to prosate cancer.
Other conditions like prostatic intraepithelial neoplasia (PIN) may be linked to raised risk of prostate cancer. Under a microsope, the cells look abnormal when examined in this PIN condition. It is not fundamentally related to any symptoms. Before the age of 50, almost one half of men will be diagnosed with PIN.
There are possibilities that some genome changes where certain genes like BRCA1 and BRCA2 genes have been studied to cause prostate cancer risk to
