A Healthier Gut Microbiome and Cancer Care: Why I’m Still Watching It After the Neurologist Said “Not for Parkinson’s”
A Healthier Gut Microbiome and Cancer Care: Why I'm Still Watching It After the Neurologist Said "Not for Parkinson's"
When you're dealing with cancer, you start paying attention to everything that might help. Dave has lung cancer, and we're always looking for anything that might augment his treatment at City of Hope. You can read a recent news story about this topic here: A healthier gut microbiome may be the key to cancer care.
Right now, we're getting ready for "zapping surgery" tomorrow — an image-guided ablation to destroy the larger tumor while hoping the immune system can handle the smaller ones. It's minor on paper, but cancer is cancer, and it still makes me nervous. Dave has done well with surgery in the past, even though Parkinson's adds some risk and a previous surgery left a hole in his upper jawbone, so this one brings up some pause.
A few years ago, we asked our neurologist about CNM-Au8, a gold nanocrystal therapy studied in Parkinson's. The answer was clear: "It is not helpful for Parkinson's, so don't waste your money. Eat yogurt." That was honest and fair.
But for cancer, the microbiome story is different. That's where fecal microbiota transplant (FMT) comes up. FMT isn't standard cancer care for most people, but early studies suggest changing the gut environment may improve treatment response, especially with immunotherapy. Our neurologist was right about Parkinson's, but cancer is a different puzzle.
Here's a quick overview of how FMT is being studied in cancer care:
This chart shows how fecal microbiota transplant (FMT) is being explored in cancer research to change the gut microbiome and potentially improve treatment response, especially with immunotherapy. FMT is still experimental for most cancer patients.
My goal isn't to replace Dave's treatment plan — it's to bring anything legitimate to our oncologist or pulmonologist if there's a reason to consider it. Here's the note I'm taking to the doctor's office:
This is the short note I'm taking to our oncologist and pulmonologist, summarizing what I've learned about the gut microbiome and cancer care and the questions I want to ask.
Questions to Ask the Oncologist or Pulmonologist
- Does the gut microbiome matter in Dave's cancer treatment plan?
- Could his treatment affect the microbiome or cause gut-related side effects?
- Is there any reason to look at diet, probiotics, or other gut-supporting steps during treatment?
- Is fecal microbiota transplant ever relevant in lung cancer care, or is that still experimental?
- Are there any microbiome-related clinical trials or supportive strategies we should consider?
Closing Note
I'm not trying to get ahead of the doctors — I just want to bring them anything that might be worth a conversation. With Dave going in for ablation tomorrow, I'm hoping for the best and staying steady.
This post was inspired by a WESH news article about the gut microbiome and cancer care, with additional background from the National Cancer Institute, Memorial Sloan Kettering, Fred Hutch, and peer-reviewed microbiome research. Our neurologist's advice about CNM-Au8 and Parkinson's comes from our own experience.
☕ This post took a lot out of me to write.
Dave goes in for ablation tomorrow. I'm researching while he naps so I can walk into that appointment with the right questions. If that kind of real-life, no-filter caregiving content means something to you — a coffee keeps the lights on and the blog running.
