In the last few years, we have seen a lot of data science being used in different industries like IT, media, entertainment, education, banking and finance, e-commerce, and especially in the health industry. The healthcare industry deals with a large amount of data, ranging from basic patient information to clinical information about a patient, all with one goal: making decisions. Most decisions frequently endanger rather than save their patients' lives. By taking a different approach, Data Science helps make better patient decisions and provides more accurate predictions for experimental procedures on patients. Data Science has also helped in the improvement of care quality. This article will look at how data science is transforming the healthcare industry. 1.Patient Health Monitoring: Doctors can use data science to remotely monitor their patients’ health statuses such as heart rate, sleep patterns, blood glucose levels, and stress levels using wearables such as smart wristwatches and health-tracking bracelets. This will alert doctors if the patient's health status changes, allowing them to make an informed decision. 2.Diagnosis: Data science applications in healthcare can help to facilitate and accelerate diagnosis, which is an essential component of medical activities. This will aid in the early detection of health problems. 3.Remote Assistance: Data Science can assist patients with unusual daily needs such as health and lifestyle information, drug recommendation, and health insurance issues. 4.Predictions: Data Science can identify patterns in historical data and make precise predictions. This will assist the doctor in anticipating any future health complications. 5.Image Analysis: To visualize the body's internal systems and organs, healthcare professionals frequently use imaging techniques such as X-Ray, MRI, and CT scans.…
