Eating fast food wrapped in PFAS laden food packaging may be a one-two punch for your prostate. A new study conducted by scientists at the University of Illinois has found that PFAS exposure together with a high-fat diet causes malignant prostate tumors to grow much faster than those without exposure to the chemical.
The scientists in the study performed several experiments. In one they exposed malignant human prostate cells to PFOS and PFBS and compared them to malignant prostate cells that were not exposed. The cancerous cells replicated three times faster than the control group when exposed to PFOS and 5 times faster when exposed to PFBS.
In a follow-up experiment, they injected mice with the malignant human prostate cells and fed them either a high-fat diet or a control diet. Some of the mice also received doses of PFOS, a common form of PFAS that has previously been linked to cancer. As expected, the mice fed a high-fat diet exhibited faster tumor growth than mice in the control group. The mice exposed to PFOS who ate the control diet had even faster tumor growth than the mice fed a high-fat diet. But the mice who were exposed to PFOS and fed a high-fat diet had the fastest rate of tumor growth of all.
