Biologist and wellness expert Gary Brecka is challenging traditional views on disease, warning that cancer is not a random occurrence but the result of cumulative assaults on the body’s immune defenses.

“Cancer doesn’t come out of nowhere. It comes when the immune system is overrun — by parasites, mold, heavy metals, and viruses,” said Brecka in a post on X.

Brecka argued that most health systems focus on treating symptoms instead of addressing the root causes of immune dysfunction. He emphasized that toxins and infections silently weaken the body over time, eventually leading to serious illness if left unchecked. According to Brecka, true resilience starts by identifying and eliminating these hidden threats, rather than reacting after disease has already taken hold.

“The longer we ignore the root causes, the longer we stay trapped in a broken cycle of sickness,” he wrote, urging people to proactively seek out the environmental and biological stressors undermining their health. He expanded on these insights in his latest talk, which is available to watch here.
