Cancer Predisposition Clinic

What is the Cancer Predisposition Clinic?

The expert team at Seattle Children’s Cancer Predisposition Clinic cares for children who are born with a gene change (mutation) that increases their chances of developing  cancer in childhood. This is called having a cancer predisposition syndrome. It does not mean a child will have cancer, but they are at greater risk compared to other children.

All during childhood, we assess your child’s risk for cancer and carry out screening. Their screening plan is tailored to their condition and based on the latest medical evidence. Such screening may allow us to find and treat tumors early, leading to better outcomes. In some cases, steps can be taken to lower your child’s risk of cancer.

  • Researchers estimate that about 10% of childhood cancers have a hereditary cause. Most cancers are due to changes in genes that happen during a person’s life. Those gene changes are found in the tumor only and not in healthy cells. They are not passed down in the family.  

    In children with a cancer predisposition syndrome, the gene change is present in all cells of their body.

    • Most often, a child inherits the syndrome from a parent who has the gene change.
    • Sometimes a child is the first person in their family to have the gene change. The gene change may be present in their parents’ egg or sperm or may happen as the embryo grows very early in pregnancy. This is called hereditary because the child can pass it on to their future children.

Who can benefit from the Cancer Predisposition Clinic?

Most children come to our clinic for screening and guidance on managing a cancer predisposition syndrome. Some come to find out if they have a syndrome.

A child may have a cancer predisposition syndrome if they or their family have a history of:

  • More than 1 tumor in the same person. This is called multiple primary tumors or bilateral/multifocal tumors.
  • Tumors with a strong hereditary component. Examples include retinoblastoma, adrenocortical carcinoma, pheochromocytoma/paraganglioma, pleuropulmonary blastoma and medullary thyroid carcinoma.
  • Early-onset tumors, such as rhabdomyosarcoma, in a young child.
  • The same tumor in more than 1 family member.
  • Tumors along with other symptoms such as developmental delays, birth defects or skin abnormalities (like areas of darker skin called café-au-lait spots).

    • Our team combines the expertise of a childhood cancer specialist (pediatric oncologist), a certified genetic counselor and nurse coordinator to provide the best care for your child.
    • We are skilled in caring for children with cancer predisposition syndromes. We will give your child evidence-based screening services designed to find tumors early. This allows early treatment, which may improve survival and lessen long-term health issues related to the tumors or treatments.
    • As part of a world-class academic pediatric hospital, we have access to specialists in many fields of medicine. One example is radiologists who can perform and interpret whole-body MRI (magnetic resonance imaging) scans.
    • If screening detects cancer, your child will receive care from Seattle Children’s doctors known worldwide for treating children with complex cancers. We provide a full range of treatment options. Our patients have access to research studies (clinical trials) of new treatments that many centers do not offer.
    • We work closely with the High Risk Cancer Surveillance Clinic at Seattle Cancer Care Alliance (SCCA). We refer adult relatives of our patients there for testing and screening. When our patients are ready, we help them transition to adult care at SCCA.
    • Having a child with a cancer predisposition syndrome can be stressful for the whole family. Our team supports your child and family through these challenges. If needed, we can refer you to mental health professionals.
