Can Curcumin Cure and Prevent Cancer?

This curry spice has all kinds of potential when it comes to preventing and treating cancer.

You’ve probably heard the buzz around curcumin. The principle component of the popular Indian spice turmeric, it’s a natural plant chemical that’s responsible for the yellow color of the spice.

The buzz, however, isn’t about the taste or how this pretty powder can jazz up your dinner menu, but how it may have potential health benefits, particularly in helping to prevent cancer.

The Mayo Clinic advises caution, as there isn’t yet enough evidence to recommend curcumin for preventing or treating cancer, but the early studies are definitely intriguing.

What is Curcumin?
Turmeric is a member of the ginger family, and is a well-known spice that’s one of the main components of curry powder. The plant is actually gathered annually, and the rhizomes—like potatoes—are used to create the spice.

Turmeric is common in flood flavoring and in Asian cooking. It’s a great spice for rice, potato salads, meat sauces, seafood marinades, stews, and braises.

Curcumin is the principle substance in turmeric that has shown health benefits. It’s long been used in Asian medicine to treat a variety of conditions, mostly those associated with abdominal pain, like diarrhea. It was also used in ancient Hindu medicine for treating swelling and sprains.

Overall Potential
According to the American Cancer Society, curcumin has shown promising results in a number of studies. Laboratory testing has shown that it can kill cancer cells and reduce the growth of any surviving cells. It’s also been found to reduce the development of several types of cancer in laboratory animals and to shrink animal tumors. And it doesn’t stop there.

“Laboratory and animal research suggests that curcumin may prevent cancer, slow the spread of cancer, make chemotherapy more effective and protect healthy cells from damage by radiation therapy,” says the Mayo Clinic. They add that clinical trials are underway to investigate curcumin as a way to prevent cancer in people with precancerous conditions, as a cancer treatment, and as a remedy for signs and symptoms caused by cancer treatments like chemotherapy.

Other studies have shown that curcumin is an effective antioxidant, and helps to reduce inflammation.

Some Specific Studies
Here are a few of the details.

  • Research published in 2003 showed that curcumin could suppress tumor initiation, promotion, and growth. “All of these studies suggest that curcumin has enormous potential in the prevention and therapy of cancer,” researchers wrote.
  • Oral administration of curcumin has been found to inhibit stomach, liver, and colon cancer in animals.
  • A study from the UCLA found that curcumin kills head and neck cancers by inhibiting cancer-fueling inflammation and growth-driving cell signaling. “We believe curcumin could be combined with other treatments such as chemotherapy and radiation to treat head and neck cancer,” researchers wrote. “It could also perhaps be given to patients at high risk for developing head and neck cancers—smokers, those who chew tobacco and people with the HPV virus—as well as to patients with previous oral cancers to fight recurrence.”
  • A small study published in 2008 in the journal Clinical Cancer Research found that curcumin temporarily stopped advanced pancreatic cancer growth and reduced the size of tumors. Even more exciting—there were no side effects.
  • Bharat Aggarwal, Ph.D., Professor of Cancer Medicine at the University of Texas M.D. Anderson Cancer Center, states that curcumin is unique and versatile as an anti-cancer agent because it can attack multiple targets linked with cancer promotion at once. “We have not been able to find a cancer we can’t effectively treat in the laboratory with curcumin,” he said. “What’s more, we haven’t been able to come up with a dose that causes toxicity.”
  • A 2012 study published in Cancer Research found that curcumin helps slow the growth of tumors in prostate cancer patients by “jamming” receptors that enable the tumor to grow and spread. Researchers said the results had implications beyond prostate cancer, since the way it fought the tumors is key in other malignancies as well, like breast cancer.
  • Curcumin was found to slow the progression from colon polyp to colon cancer by damping down inflammatory reactions and halting the growth of cancer cells. Curcumin also increases colon cancer cell response to radiation.

The studies go on and on. In fact, according to a 2011 article in Life Extension Magazine, 240 studies on curcumin and cancer were published in 2010 alone. Other research has shown curcumin’s powers can help prevent or treat leukemias, lyphomas, and myelomas, as well as brain and bladder cancers. Long-term human studies are needed to solidify the evidence behind the spice’s potential.

Other Health Benefits
Though cancer is the top area of research with curcumin right now, the spice has also shown promise in protecting against skin diseases, Alzheimer’s disease, heart failure, stomach ulcers, inflammatory bowel disease, infections, and high cholesterol.

Meanwhile, what if you want to incorporate this healthy spice into your life? Here are some tips:

  • Supplements often contain bromelain, as it helps the body absorb curcumin.
  • Recommended adult doses: 400-600 mg, 3 times per day of standardized powder; 30-90 drops a day of fluid extract; 15-30 drops four times a day of tincture; 1.5-3 grams per day of the cut root; and 1-3 grams per day of dried, powdered root.
  • Sprinkle the spice on apples sautéed in butter, on steamed cauliflower, potatoes, green beans, and onions.
  • Add some to salad dressings.
  • Add to the water while cooking rice.
  • Try adding some to your lemony-ginger tea.
  • Spice up your chicken dishes with turmeric along with your garlic powder, cayenne pepper, and onions.

Blood-thinning medications, antacids, and diabetes medications may have potentially dangerous interactions with curcumin—be sure to check with your doctor.

Since then, he’s written and edited 6 books on the subject of natural health, diet and fitness. During this time, he’s constantly been humbled by what experts claim they know and what actually is true. This has led him to experiment with many diets and protocols — including vegan, raw food, fasting, medical treatments and more — to find out what is myth and what really works in the real world.

    I’ve been using Turmeric on my fruit in the morning for years.

    I’ve known about the anti-cancer properties and with no known toxicity, it is good prevention therapy.

    Good Health…

  2. Linda says:

    I love curries and eat them frequently. I add turmeric to just about any soup I make, and take it as a supplement every day.

  3. Ionie says:

    I most definitely would encourage people to incorporate tumeric in their daily diets. I had fibroid tumors (several, small and large), to the extent that they were compared to a 22 weeks old pregnancy – the last time I did an ultra sound a few years ago. My stomach was so distended, to the point that I had lost buttons off my skirts and pants. I heard about the combination of tumeric, black-pepper and extra virgin olive oil to kill the tumors – which I did. To my utter amazement they have shrunk so small, that I can now wear my belts around my waist once more. I now use tumeric in almost everything that I eat.
