DMSO is a widely used chemical with a surprising ability to push cancer cells into a more mature, less aggressive state.
It has shown promising results against multiple cancer types, including leukemia, lung, liver and prostate cancers.
When combined with traditional drugs, DMSO can enhance treatment effectiveness while reducing toxicity.
Its safety profile is strong and it is already approved for use in medical settings.
Lack of financial incentives has stalled research, but growing interest in affordable alternative therapies may change that.

In the world of cancer treatment, hearing about high-tech breakthroughs, billion-dollar drugs and cutting-edge immunotherapies is not new. But one of the most promising cancer-fighting agents has been hiding in plain sight for over half a century – quietly working in laboratories and preserving frozen cells. Meet dimethyl sulfoxide or DMSO. This humble chemical – already used in hospitals for other purposes – may hold a surprising secret: the ability to reprogram cancer cells and boost the effects of traditional therapies. Scientists are beginning to take a second look at DMSO and what they're finding could change how people think about cancer treatment. Originally derived from wood pulp, DMSO is a clear, odorless liquid that has been used for decades as a solvent – a substance that helps dissolve other materials. It is also known for its role as a cell preservative and a skin-penetrating drug delivery agent. In 1978, the U.S. Food and Drug Administration (FDA) approved a 50 percent solution of DMSO, marketed as Rimso-50, for the treatment of interstitial cystitis (IC) via intravesical instillation (direct administration of the liquid into the bladder through a catheter). A December 2023 study published in the journal Continence reported continued effectiveness of DMSO for IC, reinforcing its clinical relevance decades after its initial approval. In short, DMSO is a multitasker. But beyond its practical uses, researchers are now exploring something far more intriguing: its ability to "nudge" cancer cells into behaving more like healthy ones. This process – called differentiation – could be a game-changer. In cancers such as leukemia, lung, liver and prostate tumors, DMSO has been shown to coax immature, aggressive cancer cells into becoming more mature, less dangerous versions of themselves.

Teaching cancer cells to "grow up"

Cancer cells are like rebellious teenagers: wild, unregulated and uninterested in becoming responsible, functioning members of the body. Most cancer cells refuse to "differentiate," staying in a stem-like, rapidly dividing state. That's where DMSO comes in. In a landmark 2023 study published in Cancer Diagnosis & Prognosis, researchers showed that DMSO could trigger differentiation in leukemia cells, pushing them to mature into functioning white blood cells – cells that no longer divide recklessly or spread disease. Even more impressively, this wasn't limited to leukemia. In laboratory studies, DMSO showed similar effects across multiple cancer types, including:

Liver cancer, where DMSO not only slowed tumor cell growth but also reshaped their gene activity, potentially making them more visible to the immune system.
Lung cancer, where DMSO enhanced the power of interferon-alpha, a common cancer drug.
Prostate cancer, especially treatment-resistant forms, where DMSO lowered key receptors that fuel tumor growth.

In each case, DMSO didn't just damage cancer cells – it encouraged them to return to a more normal, less threatening state.

DMSO as a cancer therapy partner

While DMSO alone shows promising anticancer effects, it may be even more powerful when combined with conventional therapies. In lung cancer studies, DMSO made cells more responsive to interferon-alpha, a drug that's notoriously difficult to tolerate on its own. In other models, DMSO worked alongside doxorubicin and 5-fluorouracil – two well-known chemotherapy agents – to make tumor cells more vulnerable to treatment. It also appears to have immune-activating potential. In liver cancer cell experiments, DMSO altered the activity of over 1,200 genes, many of them involved in immune responses. This hints at a possible role for DMSO in immunotherapy, by making tumors more recognizable to the body's natural defenses. And perhaps, more importantly, all of this was achieved at low doses – minimizing toxicity while preserving effectiveness.

Is DMSO safe?

DMSO has been safely used in medical settings for decades. Its most noticeable side effect? A temporary garlic or onion-like body odor caused by how it is metabolized in the body. Other side effects – like mild skin irritation or nausea – are rare and typically associated with high doses or improper use. When used responsibly and at the right concentrations, DMSO has an excellent safety profile. In fact, doctors already use it regularly to preserve stem cells during CAR-T cell therapy and other regenerative treatments. DMSO is cheap, generic and non-patentable. That means pharmaceutical companies cannot make billions off it, so there's little financial incentive to fund the large-scale clinical trials needed to turn DMSO into a mainstream cancer therapy. This leaves it stuck in limbo – praised in academic studies, quietly used in labs, but never fully embraced by the medical establishment. One researcher noted that it's not that DMSO doesn't work – it's that no one is willing to invest in proving it and that's a huge missed opportunity. But change may be on the horizon. As interest in natural, low-toxicity treatment grows, so does support for independent clinical research. Nonprofits, research institutions and grassroots medical communities are beginning to take the reins, asking whether DMSO deserves a second shot. DMSO is a rare thing in medicine. It's versatile, well-studied, widely available and remarkably safe. It doesn't aim to destroy cancer with brute force. Instead, it disarms tumors, re-educates rogue cells and makes other therapies more effective. Imagine a future where DMSO becomes a standard part of cancer care – not because it's flashy or high-tech, but because it works. Watch this video to learn more about DMSO.
