Cancer Screening | Community Health

Cancer screening is the process of detecting cancer before symptoms appear, using methods such as blood tests, urine tests, DNA tests, and medical imaging. The goal of screening is to identify cancer early, making it easier to treat and increasing life expectancy. With cancer being the second leading cause of death globally in 2019, screening plays a crucial role in preventing cancer and providing early diagnosis. According to the [[world-health-organization|World Health Organization]] (WHO), cancer screening can reduce mortality rates by up to 30%. The [[american-cancer-society|American Cancer Society]] recommends regular screening for certain types of cancer, such as [[breast-cancer|breast cancer]] and [[colorectal-cancer|colorectal cancer]]. As of 2022, over 100 million people worldwide have undergone cancer screening, with the [[national-cancer-institute|National Cancer Institute]] providing funding for research and development of new screening technologies.
