Fasting Might Boost Chemo's Cancer-Busting Properties

As a cancer grows and its cells mutate, they become more specifically adapted to the environment—a tactic that often spell success for the malignancy. But, Longo says, "if you start changing the environment" by fasting, it has more trouble surviving chemo assaults than healthy tissue cells. Cancer cells, at least in breast cancer experiments, seemed to be fighting to stay alive in the starvation–chemo environment by eating up even more energy, which stresses the malignant cells and causes more damage in them.
Mary Helen Barcellos-Hoff, a professor at the New York University Langone Medical Center who was not involved in the new research, wonders if fasting is also having other effects in the body that is making it less hospitable to cancer, say by increasing immune system sensitivity to the cancer or helping to squelch vascularization of tumors. "I really think modifying the microenvironment to make it less permissive is really one of the untapped potentials for future cancer therapies, she says."
But as Longo notes, fasting—for two to three days in mice, which would be the equivalent of four to five days in humans—alters the body in myriad ways. "You look at their blood, everything changes," from the factors that control blood vessel growth to acids, he says. So now he and his team are going back to look for different signs of what is changing the fasting and chemo in hopes of further optimizing the timing and treatments.
Faire de l'exercice intense, changer totalement ce qu'on mange ( surtout si malbouffe ) est aussi un moyen de changer l'environnement des cellules !!
