Phase 1 · Understand the Body — Why the disease behaves the way it does.
The One-Line Truth
The whole disease in one chain
Everything on this page exists to explain this line.
Prostate cancer is very common, usually grows slowly, and often needs watching more than treating right away.
A malfunctioning factory with faulty security and overpowered fuel
Imagine the prostate is a small factory that normally makes one product (reproductive fluid) and follows strict safety rules. The DNA is like the factory's instruction manual — it has built-in safety brakes (tumor suppressors like PTEN) that say "stop making more product." Testosterone is like high-octane fuel that powers the factory's machines, delivered by a delivery truck (blood) and unlocked by a special key (androgen receptor) at the factory door. When the manual gets damaged by age and wear, the safety brakes break, and the factory starts running without limits. The factory then demands MORE fuel, the delivery system keeps feeding it, and soon the factory overgrows its building, busts through the walls (capsule invasion), clogs nearby pipes (the urethra tube), and sends poisonous waste products into the bloodstream that travel to distant bone-storage warehouses, where they trigger chaotic remodeling. Cutting off the fuel (blocking testosterone) is like unplugging the factory's power supply — it slows production dramatically, but eventually some factories learn to run on a backup generator (castration resistance).
