Stretching – fight tumors, boost immune system

Stretching – fight tumors, boost immune system
Apologies, I’ll try posting this again. Somehow html tags get inserted from pasting and it futzes with the website, and no one can reply.
https://link.springer.com/article/10.1186/s12915-026-02543-5 “Stretching inhibits tumor growth in MMTV-PYMT via a direct mechanical effect” (February 2026)

They did a study in mice and discovered “Our previous study revealed that daily gentle stretching (~ 25% strain) for 10 min reduced the growth of P53/PTEN − / − orthotopic mouse mammary tumors by 50%.”
If you want to research and discover more about this phenomenon, the mechanisms are called “fascial mechanotransduction” and “The CHA axis (Calcium–Hyaluronan mechanotransduction loop)”.
Bottom line – stretching and creating sheer force on your fascia results in an immune boosting effect.
Here’s the AI summary:
Two key findings from the literature:
* Stretching reduces pro‑inflammatory cytokines (IL‑6, TNF‑α, COX‑2) and increases anti‑inflammatory cytokines (IL‑10).
* Chronic inflammation supports tumor growth, angiogenesis, and metastasis. Reducing inflammation can therefore create a less favorable environment for tumors.
This is the biological bridge: stretching → lower inflammation → less tumor‑supportive microenvironment.

Thanks for the share @jrgerber … I know its anecdotal, but when I do deep stretches and yoga I feel the effects on the whole body and mind.

@IMA-HelenT I feel the same way. I guess the body tells the mind when something is good for you, but perhaps we don’t always appreciate just how good it is or know exactly what it is doing. It’s fun when science can tell us some facts like this!
We all generally know that movement is good for us, but finding out that stretching puts tension on fascia and fascia then do some profound things for our health is incredible.
I enjoy Yin Yoga. Stretches on the floor with holds for minutes. My mind relaxes deep like the stretch itself. But now I know my immune system is getting a major boost too.

Thanks much for this common sense, and what sounds like from my scattered reading thus far, extraordinarily very helpful information for our health.
I work hard to lower Crp. My heart doc always focuses on that for me, in light of my aneurysm.
Why don’t the smart whips in the medical side of our government prioritize locating information like this – my goodness —
Well, Blessed day, one day at a time,
