Long praised for its anti-inflammatory properties, it’s now making headlines for its potential role in cancer treatment and prevention.
Here are some key facts that highlight what science currently knows about the spice and cancer.
The active ingredient
Curcumin is the compound in turmeric responsible for its bright yellow color and potential health benefits.
It's widely studied for its anti-inflammatory and antioxidant properties, which might help combat disease.

Shows promise against multiple cancer types
Studies suggest that curcumin can fight cancer cells from various types of cancer, including lung, breast, prostate, and colon.
However, these findings mostly come from cell or animal studies, not human trials.
May enhance chemotherapy effectiveness
Some research indicates curcumin could make chemotherapy more effective.
In certain cases of advanced pancreatic or colorectal cancer, curcumin may help cancer cells become more responsive to treatment.

Slows progression in colorectal cancer
A study involving people with colorectal cancer found that daily curcumin intake could help slow the disease's progression.
This positions turmeric as a potentially valuable addition to cancer treatment plans.
Possible preventative effect for high-risk individuals
Other research suggests curcumin might lower the risk of developing cancer in people with elevated risk levels.
This makes it a candidate for future preventative treatments, though more evidence is needed.

Mixed results from clinical trials
While some clinical studies in humans have shown encouraging results, the overall evidence is still inconclusive.
Most available data come from early-stage or small-scale trials, so large-scale studies are required.
Relief for treatment side effects
One study found that a turmeric-based mouth rinse helped relieve painful mouth sores in patients undergoing radiotherapy for head and neck cancers.
This suggests turmeric might ease certain treatment-related symptoms.

No benefit for radiation-related skin issues
In contrast, another study found turmeric had no effect on skin problems or pain in breast cancer patients receiving radiation therapy.
So its benefits may not be universal across symptoms.
Poor absorption in the human body
One major limitation is that curcumin isn’t easily absorbed by the body.
Most of it passes through the digestive system without being fully utilized, which may limit its effectiveness unless specially formulated.

Generally safe, but with caveats
Turmeric is safe for cooking and typically causes few side effects.
However, high doses may lead to stomach upset, and curcumin could interfere with certain cancer medications.
Always consult a doctor before starting supplements, especially during cancer treatment.
