Early detection of a cancer means much better chance of a cure. Some cancers, such as skin & breast cancer are relatively easy to detect early because they can be detected by sight or touch. Others, such as pancreatic cancer as more difficult.
Recently, a high level of certain amino acids has been found to indicate an elevated risk of pancreatic cancer years later.
