Cancer becomes far more dangerous when it spreads from its original location to other parts of the body.
This process is called metastasis, and it is the main reason why cancer leads to death. Many people think the original tumor is the biggest problem, but in reality, it is the spread of cancer that causes the most harm.
When cancer cells break away from a tumor, they can travel through the bloodstream or the lymph system. These cells can settle in new places, such as the lungs, liver, or bones, and begin to grow again.
These new growths are often very small at first and cannot be seen with scans or removed during surgery. Because of this, doctors often worry that even after a tumor is removed, some hidden cancer cells may still remain in the body.
To reduce this risk, many patients receive chemotherapy after surgery. Chemotherapy uses strong drugs to kill cancer cells. The goal is to destroy any cells that might have escaped before they can form new tumors. While chemotherapy can be effective, it also has side effects. One of these is inflammation, which is the body’s natural response to injury or stress.
Inflammation is meant to help the body heal, but in the case of cancer, it can sometimes have the opposite effect. Instead of stopping cancer, it may create an environment that helps cancer cells survive and spread. This creates a difficult problem for doctors, because the very treatment meant to stop cancer might also help it return.
Researchers at Emory University have been looking for ways to solve this problem. They have found a surprising possibility in a drug that has been used for many years: ketorolac.
This medicine is a type of painkiller known as a nonsteroidal anti-inflammatory drug, or NSAID. It is similar to common drugs like ibuprofen and is often used to treat short-term pain after surgery.
Ketorolac is already approved by the U.S. Food and Drug Administration, but doctors do not usually use it for long periods because it can have side effects. However, its ability to reduce inflammation made researchers wonder if it could also help prevent cancer from spreading.
In a study led by Dr. Vikas P. Sukhatme, scientists tested this idea using mice. They gave ketorolac to the mice before surgery. The results were very promising. The drug helped the immune system find and destroy cancer cells that had begun to spread. Mice that received ketorolac developed fewer new tumors and lived longer than those that did not receive the drug.
This finding may also help explain something doctors noticed years ago in human patients. Some breast cancer patients who were given ketorolac during surgery seemed to have a lower chance of their cancer returning.
At the time, no one fully understood why this happened. The new study suggests that the drug’s ability to reduce inflammation and support the immune system may be the reason.
The researchers also explored whether ketorolac could work even better when combined with other substances. They added low-dose aspirin and omega-3 fatty acids, which are healthy fats found in fish oil. Both of these are known to reduce inflammation as well.
When all three were used together, the results improved even more. The mice showed stronger immune responses, fewer signs of cancer spread, and higher survival rates. This suggests that a combination of simple, widely available treatments might help the body fight cancer more effectively.
The idea behind this approach is simple. Cancer cells often take advantage of inflammation in the body to grow and spread. By reducing inflammation, drugs like ketorolac and aspirin may make it harder for cancer cells to survive. At the same time, the immune system may be better able to recognize and destroy these harmful cells.
Although these findings are exciting, it is important to remember that this research is still in the early stages. Studies in animals do not always produce the same results in humans. Scientists need to carry out more research to understand how ketorolac works in different types of cancer, what doses are safe, and how to avoid possible side effects.
Even so, this study offers hope. If future research confirms these results, ketorolac could become a simple and affordable way to help stop cancer from spreading. It could be used alongside existing treatments to improve outcomes for patients and reduce the risk of cancer returning.
The study was published in the Journal of Clinical Investigation. It shows that new ideas in medicine do not always come from new drugs. Sometimes, medicines that have been used for decades may have hidden benefits that scientists are only just beginning to understand.
For patients and doctors, this research is a reminder that fighting cancer requires many different strategies. Surgery, chemotherapy, and new treatments all play a role. Adding a common painkiller to this list may seem surprising, but it could one day make a real difference.
Researchers are continuing their work to bring these findings closer to real medical use. Their goal is to turn this simple idea into a treatment that can help save lives. If successful, it would be a powerful example of how small changes can lead to big improvements in cancer care.
