Human patients suffering from prostate cancer show tumor-stage-dependent depression circadian serum rhythms when compared to age-matched with benign tumors. To prove involvement olfactory or geomagnetic factors as zeitgebers for seasonal rhythms, experiments will have performed under complete shielding such influences that require highly sophisticated setups. Irrespective acting synchronization endogenous controlled laboratory conditions, fact remains cannot easily extinguished, neither humans nor animals.
