Prostate cancer is the most common cancer in men and occurs in the male reproductive system (Williams, 2013). Few known and many unknown risk factors are linked to prostate cancer, including family history, age, and diet (Zatzkin, 2013.) Prostate cancer has many unclear and unknown causes, being Because it is a serious and fatal type of cancer, no specific cause has been established. established (Chavarro, et al, 2013). Much research has been conducted to find cures, although only certain preventive methods have been proven to work. Say no to plagiarism.

The risk of developing this disease may increase if one member of the family suffers from first-degree prostate cancer or if several family members suffer from prostate cancer (Williams, 2013). Risks are also influenced by age at diagnosis. Most develop prostate cancer after the age of 50, but most are not diagnosed until around age 65. If prostate cancer goes undiagnosed for too long, it could eventually spread throughout the body and lead to bone cancer (Zatzkin, 2013). ). Lesser risk factors that can still put a person at risk of developing this disease include diet. Diets high in fat, high in red or processed meats, and high in milk or dairy products are all minor risk factors (Zatzkin, 2013). Factors that are not entirely known to put anyone at risk, but are nevertheless suggested, include: inherited genetic mutations, inflammation of circulating testosterone in the prostate, pesticide exposure, and occupational exposures (Canadian Cancer Society, 2013 ). Prostate cancer has many unclear causes; According to doctors, prostate cancer begins when normal living cells in the prostate become abnormal (Hensrud, 2013). These cells contain a mutation in the DNA and therefore become cancerous (Hensrud, 2013). Unusual mutations in cells produce rapid growth and division and create a longer lifespan than ordinary cells (Varmus & Weinberg, 2013). Characteristics that allow these cancer cells to do this include: larger and multiple nuclei, variation in shape, disorganized arrangement, disorganization, greater numbers of dividing cells, and coarse chromatin (Tweddle, 2013). Large amounts of these abnormal cancer cells can eventually cause tumors to form, growing on surrounding tissues and spreading to other parts of the body (Varmus & Weinberg 2013). No known cause has been identified, although numerous research studies have been concluded to provide possible causes (Chavarro et al, 2013). A study proves through animal experiments on mice that behavioral stress promotes cell death and delays tumor shrinkage (Hassan, et al, 2013). The results of this study demonstrated interactions between a person's psychosocial environment and the prostate tumor itself (Hassan et al, 2013). Other general factors that contribute to the cause of prostate cancer are genetics, age, general diet and as stated above; stress (Zatzkin, 2013). There is no proven way to, 2013).
