Early detection of cancer significantly increases the chances of successful treatment and survival. When cancer is identified at an early stage, it is often localized and has not yet spread to other parts of the body. Early-stage cancers can usually be treated more effectively with less aggressive treatments, reducing the risk of severe side effects. According to medical research, early detection through regular screenings, such as mammograms for breast cancer and colonoscopies for colorectal cancer, can lead to better outcomes and lower mortality rates.
