Physical activity has traditionally been associated with promoting overall health, and new evidence suggests that it may also play a role in the body’s resistance against breast cancer. A recent study carried out by Finnish researchers at the University of Turku has revealed that regular exercise has the potential to enhance cancer-fighting cells in the body.
The investigation involved 20 breast cancer patients who had not yet undergone any medical treatment. These patients were instructed to engage in a 30-minute session of exercise on a resistance-based cycling machine. Blood samples were taken before, during, and after the exercise, revealing a noteworthy increase in the number of cancer-destroying white blood cells, or T cells, within their bodies subsequent to the exercise.
Tiia Koivula, the primary author of the study, explicated that the equilibrium of various types of white blood cells in the body is determinant of whether the immune system functions to eradicate cancer or to encourage it. She emphasized that having a greater amount of cancer-destroying cells relative to cancer-promoting cells in the affected area can substantially enhance the body’s ability to combat cancer.
Yet, further research is required to ascertain whether the white blood cells generated through exercise migrate to the affected regions of the body. Koivula indicated that the numbers of nearly all white blood cell types reverted to resting values within one hour post-exercise. She added that although the destination of the white blood cells following exercise remains uncertain, preclinical studies have indicated that cancer-destroying cells have been observed to move into the tumor area.
The researchers also explored the potential impact of breast cancer type and progression on the production of white blood cells. According to their findings, individuals with larger tumors produced fewer cancer-fighting cells, as did those with hormone-receptive forms of cancer. Despite these initial findings, it is essential to recognize that exercise and anti-inflammatory diets should only constitute a component of a comprehensive cancer treatment regimen determined in collaboration with the patient’s physician.
For individuals who suspect that they may have breast cancer, it is vital to be vigilant for symptoms such as a lump or swelling in the breast, alterations in the skin, changes in the nipple, unusual discharge from the nipple, or variations in the size or shape of the breast. Moreover, the most common indication of breast cancer in men is a lump in the chest area. While the majority of breast changes, including lumps, are non-cancerous, it is imperative to seek consultation with a GP regarding any new or unusual changes, and to perform regular self-examinations of the breasts.
To conclude, this study has brought to the fore the potential association between exercise and the body’s capacity to combat cancer. While sustaining a consistent exercise regimen and adopting a nutritious diet may yield favourable outcomes, it is imperative to engage in discussions with a healthcare professional for a thorough and comprehensive approach to treating cancer. In cases of concern regarding breast cancer symptoms, it is crucial to seek prompt medical advice for an accurate assessment and diagnosis.
