Causes of Prostate Cancer
The prostate is a gland found only in men, which is located just under the bladder. The tube through which urine flows out of the bladder when you pass water goes through the prostate gland then out through the penis. The prostate gland can become enlarged in several guys as they get older which then causes difficulty with bleeding.
The job of the prostate gland is to produce fluid that forms part of semen and helps to nourish sperm. The prostate gland sits in the front of the rear passage or"anus" which is the reason if a physician wants to examine the prostate gland that they feel it by putting a finger into your back passage. This is also called a"digital rectal examination" or DRE for brief. From feeling the prostate gland the physician can tell how enlarged the gland is and whether it feels normal or cancerous, this can then offer a photo of prostate cancer if it exists.
Cells in the prostate gland are constantly turning over to replace old with brand new but sometimes this process can escape control. Cancer is the name for cells which have lost control of their renewal process and begin to grow unchecked. They develop to a group of cells called a"tumour". As the cells grow that they can start to invade cells.
This invading procedure is known as acting in a"malignant" fashion. Cells can break off the tumour and spread to other websites within the body, usually via the blood stream. The cells can then grow where they have settled, often in remote parts of the body like the bones or brain. These deposits tend to be called"secondaries" or"metastases". These deposits aren't brand new cancers but are groups of cancer cells spread from the initial or"primary" cancer in the thyroid gland.
Most frequently in prostate cancer this procedure for tumour growth followed by invasion then metastasis is comparatively slow and can happen over several months or even years. That is the reason some men may have prostate cancer but not have a problem because of this i.e. their prostate cancer grows so slowly that other ailments or disorders (e.g. heart attack or stroke) cause problems or even death prior to the prostate cancer has grown far enough to trigger symptoms or spread in the prostate cancer.
With modern remedies many men with early prostate cancer can be cured and in many more the prostate cancer can be controlled and the intrusion procedure slowed even more. Prostate cancer survival rates vary widely across the world, although detection in 3rd World nations is frequently poorly catalogued.
The cause of prostate cancer is not known. What is known is that the characteristics of those guys who tend to develop prostate problems. These are called"risk factors" i.e. guys with these traits are in greater risk of developing the cancer. However it is important to realise that ALL guys are in danger of prostate cancer as well as young guys who do not have any history of cancer in their family members may develop prostate cancer.
Age is the main risk factor for developing prostate cancer. As men age they have a higher likelihood of creating all types of cancer including cancer of the prostate. Prostate cancer is quite rare under age 50 decades however four out of every ten guys who are 70 years or older will have the illness. A number of these guys will live normally without understanding they have prostate cancer and with no giving them any symptoms or prolonging their life span.
We know that the male hormones tend to stimulate the development of prostate cancer and prostate cancer is quite uncommon in men who have been castrated before age 40 years. This is very likely to be because the normal prostate gland is affected by male hormones when carrying out its normal functions within the body. Prostate cancer cells appear and have some features like these normal prostate cells including being influenced by male hormones.
Prostate cancer is seen more commonly in certain cultural groups e.g. African-Americans.
Diet may have an impact on the development of prostate cancer. Prostate cancer is more common in men who have a"western" diet high in saturated fats. Processed fats can be found in meats like beef, lamb etc and in certain dairy create e.g. butter and things made with butter e.g. cakes, snacks etc., and also in processed foods e.g. prepared meals.
It seems that guys who have a diet high in saturated fat are at increased risk of developing prostate cancer. It's also widely believed that a diet high in vegetables and fruit helps to prevent many cancers. This might be through the actions of cancer protective compounds found in many fruit and vegetables known as"anti-oxidants". This is only one of the reasons it's advisable that we include five servings of fruit and vegetables in our diet each and every moment.
