The impact of early cancer detection and the treatment outcomes vary, as there are instances where even with available treatment, early detection may not enhance the overall survival. If the cancer screening does not change the treatment outcome, the screening only prolongs the time the individual lived with the knowledge of their cancer diagnosis.
Colorectal cancer. Researchers have seen more young people diagnosed with and die from colorectal cancer. Diagnoses of people under 55 doubled from 11% in 1995 to 20% in 2019, according to the ACS.
Therefore, earlier detection alone is not enough to achieve longer survival. [citation needed] Lead time bias affects the interpretation of the five-year survival rate, effectively making it appear that people survive longer with cancer even in cases where the course of cancer is the same as in those who were diagnosed later.

With early detection and treatment, the chances of remission are extremely high. Tan says a person with Stage 0 breast cancer is 99 percent as likely to live at least 5 years after diagnosis as ...
The five-year survival rate for many cancers when caught early is at least 90%, ... families and loved ones could celebrate survivorship thanks to accessible early cancer detection through H.R ...
So statistics of survival time since diagnosis tends to increase with screening because of the lead time introduced, even when screening offers no benefits. If we do not think about what survival time actually means in this context, we might attribute success to a screening test that does nothing but advance diagnosis. As survival statistics ...
A major effect of routine breast screening is to greatly increase the rate of early breast cancer detection, in particular for non-invasive ductal carcinoma in situ (DCIS), sometimes called "pre-breast cancer", which almost never forms a lump and which generally cannot be detected except through mammography. While this ability to detect such ...
Patients were followed for two years in a preliminary analysis; Hwang plans to continue following the women and comparing their cancer rates at five years and 10 years.
