A new study presented in the United States has revealed a hopeful breakthrough in the fight against cancer. Canadian researchers have found that something as accessible as physical exercise can significantly increase survival rates in patients with colon cancer. This discovery has caused great interest among oncologists and health professionals around the world.
For 17 years, the Canadian Cancer Trials Group team has monitored nearly 900 patients with advanced-stage colon cancer. After completing their surgery and chemotherapy treatments, half of them were enrolled in a structured physical exercise program for three years. The other group only received educational materials and general recommendations about healthy habits.
Physical exercise: the new ally in the fight against cancer
The main goal of the study was to determine whether exercise can act as another treatment, on the same level as traditional medical methods. Through brisk walks or moderate jogging, three to four times per week, the participants managed to keep the recommended physical activity. The entire process was supervised by specialized professionals who adapted the exercises to each case.
The results have been compelling and have changed the perception of exercise in the oncology field. The survival rate was 90% among those who participated in the program, compared to 83% in the group that didn't. In addition, the risk of death was reduced by 37%, which translates into a very significant difference in clinical terms.
The researchers have emphasized that this intervention doesn't aim to replace chemotherapy or surgery. Rather, they propose integrating exercise as a complementary part of the patient's overall treatment. In that sense, they stress the importance of having trainers and physical therapists on oncology medical teams.
This is how this treatment is changing around the world
The study, published in the journal New England Journal of Medicine, was led by Kerry Courneya and Chris Booth, experts in exercise and cancer. Both agree that the benefits of exercise are comparable to those of many drugs, and in some cases even greater. They have highlighted that it is a safe, cost-effective treatment with few side effects.
Spanish experts have also positively assessed this finding. Mikel Izquierdo, professor of Health Sciences, has stated that this trial marks a turning point in oncology. According to him, the level of evidence achieved is sufficient to modify current clinical guidelines and introduce exercise as part of the treatment.
For many patients, professional support has been key to the program's success. Some of them claim that without that personalized follow-up, they wouldn't have managed to keep the routine. Motivation, consistency, and commitment have made the difference over these years.
A simple habit that can save lives
In recent years, evidence had already accumulated about the benefits of exercise on the well-being of cancer patients. It was known that it could reduce anxiety, fatigue, or the side effects of chemotherapy. However, this study has shown for the first time that it can also directly increase the chances of survival.
The researchers have opened a new path for cancer treatment that could change millions of lives. The message is clear: exercise isn't just a complement, but a therapeutic tool with a scientific basis. Now, the challenge is to make it accessible for all patients who need it.
