Abstract
[...]
Based on the available evidence, one egg/day is unlikely to adversely affect overall disease risk.
[...]
Prostate cancer
A meta-analysis that included 10 prospective cohort studies found that egg intake [...] was associated with higher risk of fatal prostate cancer (RR = 1.47, 95% CI 1.01–2.14) (18).

They cite (reference 18) Keum et al. 2015:
"[...] For other cancers investigated, the summary RR for an increase of 5 eggs consumed/week was [...] 1.47 (95% CI 1.01, 2.14, n 609 cases) for fatal prostate cancer, with evidence of small-study effects (P Egger= 0.04). [...] a positive association between egg intake and [..] fatal prostate cancers cannot be ruled out.

Prostate cancer
A total of [...] four studies [...] examined fatal prostate cancer (609 cases; range 0.3–6.8 eggs/d). [...] for fatal prostate cancer, an increase of 5 eggs consumed/week was associated with an approximately 47 % elevated risk (RR 1.47, 95 % CI 1.01, 2.14, [...]). When the serving size of egg consumptions was changed from one egg to two eggs for studies [...] that needed such assumption, the effect size was attenuated (RR 1.23, 95 % CI 0.97, 1.55 [...]). [...] Evidence of small-study effects, such as publication bias, was evident (P Egger= 0·04), with relatively smaller studies reporting a stronger linear association [..].
[...]
The present study provides only limited evidence to support a direct linear association between egg intake and the risk of [...] fatal prostate cancers.
