The Natural History of Hereditary Colorectal Cancer Syndromes: From Phenotype to Genotype? Where Do We Stand and What Does the Future Hold?

Applying the concept of a "natural history" to hereditary colorectal cancer is an interesting exercise because the way the syndromes are approached has changed so drastically.

In this article the diagnosis, along with endoscopic and surgical management of hereditary colorectal cancer are discussed in the context of their history and the changes in genomics and technology that have occurred over the last one hundred years.
