Sweet cherries are enjoyed in many ways, from pies and cobblers to smoothies and fresh fruit bowls. Besides their delicious taste, scientists are now discovering that cherries may also contain natural compounds that could help fight certain types of cancer.
A new study from researchers at Texas A&M University suggests that chemicals found in dark sweet cherries may slow the growth of an aggressive form of breast cancer.
The compounds studied are called anthocyanins. These natural substances give cherries their deep red or purple color. Anthocyanins are found in many fruits and vegetables, especially berries, grapes, and cherries.
Scientists have long been interested in these compounds because they are known to have antioxidant and anti‑inflammatory properties, which may help protect cells from damage.
In this new research, scientists wanted to understand whether anthocyanins from cherries could affect a particularly dangerous type of breast cancer called triple‑negative breast cancer. The results of the study were published in the International Journal of Molecular Sciences.
Triple‑negative breast cancer is considered one of the most difficult forms of breast cancer to treat. Many breast cancers can be treated with drugs that target specific proteins in cancer cells, such as estrogen receptors, progesterone receptors, or a protein called HER2.
These proteins help control how cancer cells grow and divide. However, triple‑negative breast cancer cells do not have these targets. Because of this, doctors have fewer treatment options available.
This type of cancer is also known to grow quickly and spread more easily to other organs in the body, including the lungs and brain. When cancer spreads from its original location to other parts of the body, the process is called metastasis. Metastasis is often the most dangerous part of cancer because it makes the disease much harder to treat.
In the study, the research team conducted laboratory experiments using mice to see how cherry anthocyanins affected tumor growth and cancer spread. The mice were divided into four groups. One group received cherry anthocyanins before cancer cells were introduced.
Another group received a commonly used chemotherapy drug called doxorubicin after tumors had already formed. A third group received both the cherry compounds and chemotherapy. The fourth group did not receive any treatment and served as a comparison.
The scientists did not only measure how large the tumors became. They also studied how the cancer spread through the body, which is an important factor in how deadly cancer can be.
The results were encouraging. Mice that received cherry anthocyanins before tumors were introduced developed tumors that grew more slowly. The researchers also reported that these mice did not show clear signs of harmful side effects during the study. In fact, they continued to gain weight normally, suggesting that the treatment did not harm their overall health.
Mice treated with chemotherapy alone experienced slower tumor growth later in the study, but some of them lost weight during treatment, which is a common side effect of chemotherapy. However, when the cherry compounds were combined with chemotherapy, the tumors slowed earlier and the mice maintained healthier body weights.
The researchers also examined what was happening inside the cancer cells. They found that the cherry compounds reduced the activity of certain genes that are linked to cancer spread and resistance to treatment. This means the compounds may interfere with some of the biological processes that allow cancer cells to grow and move through the body.
Another important observation was that the cherry compounds appeared to lower the chances that cancer would spread to other organs such as the liver, heart, kidneys, and spleen. Although the number and size of tumors varied between animals, the overall trend suggested a protective effect.
To understand these changes more clearly, scientists studied tumor tissues under a microscope. Veterinary pathologist Dr. Lauren Stranahan examined how fast the cancer cells were dividing and how far the tumors had spread into nearby organs. Faster‑dividing tumors are usually more aggressive and more difficult to treat.
The team also looked at immune cells known as T lymphocytes. These immune cells play an important role in helping the body identify and destroy abnormal cells, including cancer cells.
Researchers wanted to see whether the cancer was able to reduce the number of these immune cells, which can sometimes happen when tumors try to avoid the body’s natural defenses.
According to the researchers, the findings add to growing evidence that natural compounds found in foods may help support cancer treatment. However, the scientists strongly emphasized that these compounds are not a replacement for standard medical therapies such as chemotherapy, surgery, or radiation.
Instead, these natural substances might one day work together with existing treatments. Cancer is a complex disease, and many experts believe that successful treatment often requires a combination of different approaches rather than a single solution.
The researchers also noted that much more research is needed before these findings could apply to humans. Studies in animals do not always produce the same results in people. Scientists will need to conduct further research to understand how cherry anthocyanins are absorbed in the human body and how they might interact with current cancer treatments.
Even so, the study provides an interesting example of how compounds found in everyday foods may influence important biological processes related to cancer. As research continues, scientists hope that natural compounds like those found in cherries may one day become part of broader strategies to prevent or treat aggressive cancers.
