5 Causes And Risk Factors Of Prostate Cancer

Prostate cancer is a disease that primarily affects the elderly. It is relatively common in people above 65 years of age, although people in their 50s may also suffer from the condition. It has become a major health concern around the world during the last few decades. It is reported to be the second most common cause of cancer in men worldwide and the fifth most common cancer overall[1]. It is the sixth leading cause of cancer mortality (deaths) in men globally. According to a 2015 study published in the journal Prostate International[1], it is expected that prostate cancer might lead to 1.7 million new cases of prostate cancer and 499,000 deaths by 2030.

Prostate Cancer In India
The rate of incidence and the prevalence of prostate cancer varies across the world. It is highest in North America and lowest in South Asia. The incidence rates in India are less than one-tenth of the rates seen in the United States, however, there is a rising trend off late. According to a 2014 study titled “Epidemiology of prostate cancer in India”[2], it is the second leading cancer in men in four main Indian cities namely Delhi, Kolkata, Pune and Thiruvananthapuram.
The population-based cancer registries (PBCRs) of India showed a statistically significant increasing trend in the incidence of prostate rates in the past 20 years. The cancer projection data estimated that the number of cases will become alarmingly doubled by 2020[2]. This is the reason why every man in India should be aware of prostate cancer to diagnose it at an early stage and get it treated.

5 Causes And Risk Factors Of Prostate Cancer

The prostate is a small gland located in the lower abdomen in men. The gland is regulated by the hormone testosterone and produces prostate fluid, which is one of the components of seminal fluid or semen. When there is an abnormal growth in the prostate cells, it leads to prostate cancer. Cancer can spread to other parts of the body.
The exact cause of prostate cancer is not known. It might be related to numerous factors such as a family history of cancer, or diet. Age is one of the strongest risk factors for cancer in men as it accounts to around 85% of all cases of cancer in those aged over 65 years[3]. Some of the common risk factors of prostate cancer include:
  • Diet
  • High Body Mass Index (BMI)
  • Pesticides
  • Family History
  • Comorbid conditions
