Juvenile Polyposis Syndrome

What is juvenile polyposis syndrome?

Juvenile polyposis syndrome (JPS) is a hereditary condition that is characterized by the presence of hamartomatous polyps in the digestive tract. Hamartomas are noncancerous (benign) masses of normal tissue that build up in the intestines or other places. These masses are called polyps if they develop inside a body structure, such as the intestines. The term “juvenile polyposis” refers to the type of polyp (juvenile polyp) that is found after examination of the polyp under a microscope, not the age at which people are diagnosed with JPS.

Lynch Syndrome

Lynch syndrome, also known as hereditary non-polyposis colorectal cancer (HNPCC), is a type of inherited cancer syndrome associated with a genetic predisposition to different cancer types. This means people with Lynch syndrome have a higher risk of certain types of cancer.    

Cancer begins when normal cells begin to change and grow out of control, forming a mass called a tumor.  A tumor can be benign (non-cancerous) or malignant (cancerous), which means it can spread to other parts of the body. A benign tumor means the tumor can grow but will not spread.

Xeroderma Pigmentosum

What is xeroderma pigmentosum?

Xeroderma pigmentosum (XP) is a hereditary condition characterized by extreme sun sensitivity, leading to a very high risk of skin cancer. Eye problems are also common. Neurologic problems—including learning disabilities, progressive hearing loss, progressive neuromuscular degeneration, loss of some reflexes, and occasionally, tumors in the central nervous system—occur in some people with XP.
