Well, it turns out there are better ways to think about keeping our bodies humming

Welcome to Nutrition Facts.

I'm your host, Dr. Michael Greger.

Today we try to help our bodies fight cancer that's metastasized and we start with research

about the perils of Paul Middic acid.

The metastasis formation is the leading cause of death in cancer patients.

That's how most people die of cancer.

It's not the primary tumor, but the cancer spreading through the body.

It's estimated that metastasis is responsible for 90% of cancer deaths, with little progress

made in stopping the spread despite our modern medical armamentarium.

In fact, we can sometimes make it worse.

Epi-induced metastasis.

All the typical cancer treatments, radiation, chemotherapy, surgery, even just poking the tumors

with fine needle biopsies, have the potential to contribute to the problem.

I mean, you can imagine how cutting around a tumor, severing the blood vessels, might

lead to the migration of residual tumor cells, but why chemotherapy?

How might chemo exacerbate metastases?

Despite reducing the size of primary tumors, chemotherapy can change the surrounding tissues,

resulting in increased escape of cancer cells into the bloodstream.
