Introduction
Prostate cancer is the most common form of cancer in men,
with 47,151 new cases in the UK in 2015, 11,631 deaths in
2016, and a 1 in 8 lifetime risk of developing the condition.
1
The mortality rates of prostate cancer remain too high: men
have a 4.3% lifetime risk of dying from the disease.
2
Moreover, age-standardised mortality rates for prostate can-
cer are higher than for comparable cancers with approved
screening programmes, such as breast cancer

, highlighting
the aggressive nature of a proportion of prostate tumours.
Prostate-specific antigen (PSA)-based screening is
attractive because it is relatively non-invasive, quick and
cheap; however, while PSA-based screening for prostate
cancer is commonly used in the USA,
3
no formal prostate
cancer screening programme currently exists in the UK.
Almost 50 years ago, when Wilson and Jungner published
their renowned report on screening,
4
they recognised that
although ‘…screening is an admirable method of combat-
ing disease…’, ‘…the path to its successful achievement
(on the one hand, bringing to treatment those with
previously undetected disease, and, on the other, avoiding
harm to those persons not in need of treatment) is far from
simple…’. These remarks remain remarkably relevant in
relation to screening for prostate cancer: empirical evi-
dence for a PSA-based screening programme effectiveness
is conflicting, and the overall benefits may not outweigh
the harms.
The controversy has been highlighted by the changing
recommendations made by the US Preventative Services
Taskforce, which provides guidelines for screening in the
USA. In 2008,
5
they decided there was insufficient
evidence regarding prostate cancer screening in men < 75

Abstract
Prostate cancer is the most common cancer in men and is associated with unacceptably high mortality rates, yet an accurate
and acceptable screening programme that detects clinically significant prostate cancer remains elusive. Although there is
good evidence that prostate-specific antigen (PSA)-based screening lowers prostate cancer-specific mortality, especially
when conducted at high intensity, the harm caused by overinvestigation, overdiagnosis and overtreatment of clinically
insignificant cases arguably outweighs these benefits. Several attempts have therefore been made to improve screening,
enhancing the diagnostic value of PSA and identifying novel modalities for screening. Here, we provide a comprehensive
review of the benefits and harms, and analyse which of these novel screening methods show most promise.
