Fecal occult blood testing (FOBT), as its name implies, aims to detect subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon.Positive tests ("positive stool") may result from either upper gastrointestinal bleeding or lower gastrointestinal bleeding and warrant further investigation for peptic ulcers or a malignancy (such as colorectal cancer or gastric cancer).
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. This phenomenon is called lead-time bias. [14] A useful screening program reduces the number of years of potential life lost and disability-adjusted life years lost. However ...
The UK Bowel Cancer Screening Programme aims to find warning signs in people aged 60 to 74, by recommending a faecal immunochemical test (FIT) every two years. FIT measures blood in faeces, and people with levels above a certain threshold may have bowel tissue examined for signs of cancer. Growths having cancerous potential are removed. [139] [125]

The screening for neuroblastoma, the most common malignant solid tumor in children, in Japan is a very good example of why a screening program must be evaluated rigorously before it is implemented. In 1981, Japan started a program of screening for neuroblastoma by measuring homovanillic acid and vanilmandelic acid in urine samples of six-month ...
Colon cancer is the third most common cancer and the second most common cause of cancer death in the USA. [8] Due to its prevalence, screening protocols have been created for prevention of disease. Screening colonoscopies with or without polypectomy have been shown to decrease cancer morbidity and mortality. [9]
