What is the mean age of diagnosis for familial adenomatous polyposis?

The mean age of diagnosis for familial adenomatous polyposis (FAP) is typically around 35-40 years. FAP is an inherited condition characterized by the development of numerous colorectal polyps, which can lead to colorectal cancer if not managed appropriately. The increased risk of cancer usually prompts surveillance measures and potentially preventive surgery, starting from a relatively young age, often around the late 20s to early 30s. However, the diagnosis often occurs in the early to mid-30s, thus placing the mean age in that 35-40 year range.

This understanding emphasizes the importance of genetic screening and early intervention for individuals with a family history of FAP, making it crucial for healthcare providers to be aware of the condition and its typical presentation to ensure timely diagnosis and management.
