Excerpt
The epidemiology of prostate cancer is enigmatic. Globally, 1.6 million men were diagnosed with prostate cancer in 2015 [
1], a notable 66% rise in its incidence from the prior 10 years. It is the most commonly diagnosed cancer in men in 103 countries, yet there is marked variation in age-adjusted incidence rates across countries and populations. A panel of epidemiologists are likely to agree only on the following risk factors as “established”: older age, African ancestry, and positive family history of prostate cancer [
2]. It is the cancer with the second-highest estimated heritability [
3], and genome wide association studies have now confirmed more than 180 inherited genetic risk loci in ethnically diverse populations [
4,
5]. Taller height is also a probable risk factor for total prostate cancer [
6]. Given the global burden of this cancer, it is alarming that there are no confirmed modifiable risk factors for prostate cancer incidence overall, which complicates our etiological understanding of the disease. …
