Regular physical exercise plays a pivotal role in cancer prevention and management. Engaging in consistent physical activity not only reduces the risk of developing cancer but also enhances the effectiveness of existing cancer treatments and alleviates certain cancer-related symptoms. pubmed.ncbi.nlm.nih.gov
One of the key areas where exercise exerts its influence is the tumor microenvironment (TME). The TME consists of various components, including immune cells, blood vessels, and signaling molecules that surround and interact with tumor cells. Regular exercise has been shown to modulate the TME by affecting crucial immune cells such as T cells, macrophages, neutrophils, natural killer cells, myeloid-derived suppressor cells, and B cells. These changes can enhance the body’s immune response against tumor cells. pubmed.ncbi.nlm.nih.gov
Additionally, exercise influences intratumor angiogenesis—the formation of new blood vessels within the tumor. By normalizing this process, exercise can improve the delivery of oxygen and therapeutic agents to the tumor, potentially increasing the efficacy of treatments. Furthermore, physical activity impacts cancer metabolism, creating conditions less favorable for tumor growth and progression. pubmed.ncbi.nlm.nih.gov
When prescribing exercise for cancer patients, it’s essential to consider specific parameters, especially exercise intensity. Tailored exercise programs should be developed to ensure safety and maximize benefits, taking into account the individual’s health status and treatment plan. pubmed.ncbi.nlm.nih.gov
Incorporating regular physical activity into daily routines serves as a powerful strategy not only for cancer prevention but also for improving outcomes during and after treatment. Healthcare professionals are encouraged to integrate exercise recommendations into cancer care plans to support overall patient well-being. pubmed.ncbi.nlm.nih.gov
