Peutz-Jeghers Syndrome - GI, Pancreatic, Breast, Ovarian Cancer

Peutz-Jeghers Syndrome (PJS) is a rare genetic illness that happens when the STK11 (sometimes called LKB1) tumour suppressor gene changes. The disease causes hamartomatous polyps to grow all over the gastrointestinal (GI) tract and gives the lips, mouth, fingers, and toes a dark blue to brown colour. These polyps are usually not harmful, but having PJS greatly raises the risk of getting several cancers throughout the course of a person's life.
Individuals with PJS are at increased risk for different malignancies, particularly in the gastrointestinal system, including cancers of the stomach, small intestine, and colon. Crucially, malignancies of the pancreas, breast, and reproductive organs, particularly ovarian and cervical cancers, are strongly associated with the condition. In fact, people with PJS have a lifetime risk of cancer that can be higher than 80%, which often means they need close monitoring for a long time.
Genetic testing and looking at family history are crucial for early diagnosis. Following diagnosis, patients should undergo regular endoscopic exams, breast imaging, pelvic ultrasounds, and pancreatic screenings. Early detection and preventive care can make a big difference in the outcomes of PJS patients and lower the number of deaths from cancer.
