Interesting.
Melatonin is at the centre - which suggest sleep as well as light are factors.
Melatonin is an antioxidant. It intervenes in the hormone pathways and may moderate fat utilisation.
Depending on what it switches off re fats and hormones eicosanoids etc I suppose will determine if cancer grows, sleeps etc.
I am still trying to find more info.
I have found trials suggesting that excess omega six alters brain membrane compostion, and that the consequence is lower level of function.
The body also seeks to conserve DHA when level start dropping. What the iimplications of that are I do not know.
