Prostate cancer is the uncontrolled and malignant growth of the cells of the prostate gland. This gland is located below the bladder and helps in controlling urination and in the production of a part of semen. Many men, all around the world and especially in the U.S. die because of this disease every year.
The prostate gland becomes abnormal and starts growing in size, at an uncontrollable rate, resulting in the formation of tumors. The prostate gland secretes the fluids which are the components of semen along with seminal vesicles and the testicles. It is located right behind the bladder and is approximately, walnut sized. When a tumor grows in this gland, it interferes with proper urinary bladder control and sexual functions.
The first clue which suggests this disease is that the person finds it very difficult to urinate. However, benign prostatic-hyperplasia also known as BPH is a common and non-cancerous ailment of the prostate gland. Even though it has the same symptoms, it does not result in cancer,
The cancerous cells which are found within the prostate are not the deadly ones. However, when there is no treatment and if the tumor gets bigger, some cells break away from the gland and travel to the other parts of the body through blood or lymph. This process is called metastasis. The sites which are most susceptive are lymph nodes, seminal vesicles, bones in the pelvis and hip region and the blood.
New tumors get created and these are the ones which can cause the patient’s death. Males of Western countries suffer the most from this disease. It generally spreads very slowly but if spreads faster if the patient is young. Because of the slow rate of growth, most of the patients die of other diseases or age before the cancer can kill them.
Study has revealed that African-American men are twice as susceptible to prostate cancer as their white counterparts. The mortality rate of the former is also, significantly higher than the latter. African-American men make up the group which runs the highest risk of contracting and dying due to this disease. There are some factors which speed up the process like when a person is more than 55 years old, the hereditary factor, African-American lineage, exposure to rubber or cadmium and a diet which contains a lot of fat. Men, who have a plasma testosterone which is higher than normal, run a higher risk of getting affected by this disease.
