About Peutz-Jeghers Syndrome

Peutz-Jeghers syndrome (PJS) is a genetic condition that is diagnosed when a pathogenic variant in the STK11 gene affects the normal growth and function of a cell. The STK11 gene is a tumor suppressor that helps prevent cells from growing and dividing too fast or in an uncontrolled way. A pathogenic variant in the STK11 gene can lead to the formation of Peutz-Jeghers-type hamartomatous polyps (clumps of cells), also known as Peutz-Jeghers polyps, in the gastrointestinal tract. Most Peutz-Jeghers polyps are benign (noncancerous); however, cancer can develop. Individuals with PJS are at an increased risk for breast cancer, lung cancer, ovarian cancer, testicular cancer, pancreatic cancer, stomach cancer, small intestine cancer, and colon cancer. Individuals diagnosed with PJS also have distinct freckling of the skin frequently found around the mouth and on the lips, eyes, and fingers.

Cancer risks associated with Peutz-Jeghers syndrome include:

Cancer Screening and Risk Reduction for Peutz-Jeghers Syndrome

Understanding your risk for developing cancer as well as the options available to you for prevention, early detection, and treatment can help improve your quality of life. Clinical management guidelines for surveillance and risk-reduction strategies differ from person to person and should involve a shared decision between you and your healthcare provider who takes into account risk factors specific to you. Recommendations may include:


  • Annual pelvic examination and Pap smear (beginning between the ages of 18 and 20)
  • Clinical breast examinations every 6 months (beginning at age 30)
  • Annual screening mammogram and breast MRI (beginning at age 30)

Men and Women

  • Small bowel visualization every 2-3 years (beginning at age 18)
  • Colonoscopy every 2-3 years (beginning at age 18)
  • Upper endoscopy every 2-3 years (beginning at age 18)
  • Annual pancreatic screening (beginning at age 30-35)
