Light Exercise Reduces the Risk of Cancer Progression, According to a Study

A study in the British Journal of Sports Medicine suggests that regular exercise before a cancer diagnosis may lower the risk of both disease progression and death. According to the study, even moderate amounts of physical activity seem to have a lot of advantages. Although there is substantial evidence that physical activity lowers the mortality rate from cancer, the researchers point out that its effect on the course of the disease has not been as well established. In order to better explore this, the study looked at anonymised data from the Discovery Health Medical Scheme (DHMS), which covers around 2.8 million people and is the biggest open medical plan in South Africa.

The Vitality program, which encourages healthy habits, was connected to the data. Engaging in physical activities, such as working out with activity trackers, going to the gym, or attending fitness events, earns points for program participants. The kind, frequency, duration, and intensity of the activity are noted and converted into weekly exercise minutes.

Between 2007 and 2022, a total of 28,248 Vitality program participants with stage 1 malignancies and detailed physical activity data for the year before diagnosis were included in the study. At 44% of the total research participants, breast and prostate cancers were the most prevalent types of cancer. Between the initial diagnosis and the advancement of the disease, death, or withdrawal from the research, there was a range of one month to over thirteen years. In slightly over one-third (34.5%) of the sample, cancer progressed, but in almost two-thirds (65.5%) it did not. Additionally, although 81% lived, 19% passed away before the study's conclusion. The average time to advancement was seven months, and the average time to death was twenty months.

Three groups were formed using the participants' levels of physical activity in the year before to diagnosis: No record was made: 62 percent of those who took part Low (≤60 minutes per week): 13%. Between moderate and high (≥60 minutes per week of moderate-intensity): 25%. Physical activity in the year before diagnosis was associated with lower risks of cancer progression and death from any cause, even after controlling for potentially significant variables such as age at diagnosis, sex, economic and social status, and co-existing illnesses. People who had not reported any physical activity during the previous year had a 16% lower chance of disease progression than those who had moderate to high levels of physical activity, and those who had moderate to high levels had a 27% reduced chance.

The chance of the disease not progressing two years after diagnosis was: 74% for participants who are not active 78% of those who are not very active For people with moderate to high levels of exercise, 80% This pattern persisted over time: Following three years: 71%, 75%, and 78%, in that order Following five years: 66%, 70%, and 73%, in that order Comparable trends for overall survival were noted: The survival rates at two years were 91%, 94%, and 95%, in that order. 3 years: 88%, 92%, and 94%, in that order. 84%, 90%, and 91%, respectively, at 5 years.

Cause and effect cannot be established because this study is observational. The researchers also admit that the weight (BMI) data was not complete and that they were unable to control for other potentially significant factors like drinking and smoking. Nonetheless, they provide a number of tenable biological explanations for the results, the most important of which is how exercise boosts immunity by boosting the production of natural killer cells, lymphocytes, neutrophils, and eosinophils. Additionally, they note that by controlling oestrogen and testosterone levels, physical activity may reduce the progression risk of hormone-sensitive malignancies, including breast and prostate cancers. "Physical activity can be thought of as offering significant advantages to individuals with cancer in terms of their overall mortality and progression," they write.

Cancer patients can benefit greatly from exercise routines; the current authors cite prior research showing that physical activity affects inflammation, tumour regression, angiogenesis, and mental health outcomes.Two "The risks of certain drug interactions or adverse effects are one of the main disadvantages of pharmacological therapies," they note. There has also been research on cognitive behavioural therapy, but the stigma attached to them may keep individuals from getting the mental health care they require. Thus, more research into the potential benefits of exercise therapy is necessary.
