Wearable and digital technologies have become essential tools in cancer care, providing patients with the ability to monitor their health continuously. Wearables like fitness trackers and health sensors can monitor vital signs such as heart rate, blood oxygen levels, and physical activity, while mobile health apps collect data on symptoms, medication adherence, and treatment side effects. This real-time data provides valuable insights that allow healthcare providers to make timely adjustments to a patient’s treatment plan, enhancing overall care and patient outcomes. These technologies not only improve the accuracy of monitoring but also empower patients to take an active role in managing their condition, leading to more personalized and proactive cancer care.
