Cancer is a complex and diverse group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. Normally, the cells in the body grow and divide to form new cells. When cells in the body become old or damaged, then replaced by new cells. However, cancer cells continue to divide and grow uncontrollably, forming masses of tissue called tumors. Cancer can occur in any part of the body and can spread to other parts through the bloodstream or lymphatic system. There are many different types of cancer such as stomach cancer, colorectal cancer, blood cancer, breast cancer, prostate cancer etc. each with its own set of symptoms, diagnostic tests, and treatments.
Early detection and diagnosis of cancer can significantly improve the chances of successful treatment and recovery. Regular screenings and self-examinations can help detect cancer at an early stage when it is most treatable.
