Artificial intelligence and algorithms join the fight against cancer

BACKGROUND: Cancer is the uncontrolled growth of abnormal cells anywhere in a body. There are over 200 types of cancer. Anything that may cause a normal body cell to develop abnormally can potentially cause cancer. Inherited genetic defects, infections, environmental factors such as air pollution, and poor lifestyle choices such as smoking and heavy alcohol use can damage DNA and lead to cancer. Signs and symptoms depend on the specific type and grade of cancer and can include fatigue, weight loss, pain, skin changes, and changes in bowel or bladder function. There are many tests to screen and presumptively diagnose cancer, though the definite diagnosis is made by examination of a biopsy sample of suspected cancer tissue. Some cancers are diagnosed during routine screening examinations. Many cancers are discovered when a patient presents specific symptoms to their health care professional.
