This is maybe one of the mechanistic cause of cancer progression, but let's take a step back and see what would cause an excess PA concentration in our bodies [1], that is, other than force feeding mice with an enormous amount of dietary PA.

>>> in presence of other factors such as positive energy balance, excessive intake of carbohydrates (in particular mono and disaccharides), and a sedentary lifestyle, the mechanisms to maintain a steady state of PA concentration may be disrupted leading to an over accumulation of tissue PA ...

Business as usual.
