What screening may be recommended for Cowden syndrome?

[Genetic Counselor]

Screening for Cowden syndrome is intended to find certain cancers or concerning changes early, when they may be easier to manage. The plan is tailored to the person’s age, health, family history, and previous findings. Recommendations differ somewhat across guidelines, so screening ages should be confirmed with the clinician or genetics team overseeing care.

Depending on the guidance followed, monitoring may include thyroid ultrasound and clinical examination. Recommendations for when to begin ultrasound in children vary: some guidelines start at age 7, while the current GeneReviews schedule lists age 12. This difference is one reason to get an individualized plan rather than relying on a general online schedule. If a thyroid nodule is already known, the clinician may recommend a different approach.

For women with PHTS, breast surveillance may include breast MRI and mammography, often beginning around age 30 to 35 in some guidance. Other recommendations begin MRI earlier. The schedule may be adjusted when a close relative developed breast cancer at a young age. A high-risk breast clinic can discuss screening choices and how to balance the benefits and burdens of each option.
Colonoscopy is commonly recommended from around age 35, with the timing and repeat interval adjusted for symptoms, family history, and the number or type of polyps found. Kidney imaging may be considered from around age 40, though some guidance begins in the mid-to-late 30s. Skin checks and education about possible melanoma symptoms may also be included.

For endometrial cancer, a key part of care is knowing to seek medical advice for abnormal or unexpected vaginal bleeding. Some guidelines do not recommend routine screening for people without symptoms, while others discuss additional monitoring in selected circumstances. A clinician can explain the approach appropriate to the person.

Screening plans can change as a person gets older or as new findings and updated guidance become available. Family history may lead a clinician to recommend starting some checks earlier. Screening is not a guarantee that cancer will be prevented or found, and no single schedule fits everyone. It is best to keep a written plan listing which checks are due and when, and to contact the care team if symptoms arise between appointments.
