Living with Familial papillary or follicular thyroid carcinoma

Thyroid cancer that runs in families, usually of the papillary or follicular type, often in younger people.

Understanding Familial papillary or follicular thyroid carcinoma

Familial papillary or follicular thyroid carcinoma is a thyroid gland cancer with a genetic link that develops within the same family.

Current studies suggest it is inherited in an autosomal dominant way. It is often found in more than one spot in the thyroid and on both sides, and it usually affects younger patients. It is listed as starting in adulthood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Enlarged thyroid in the neck (goiter)
  • Thyroid with several lumps (nodular goiter)
  • Swollen lymph nodes
  • Head and neck tumor
  • Follicular thyroid carcinoma

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include cancer specialists, genetic specialists and hormone specialists.

  3. Ask which tests can help

Changes in genes cause it. Studies suggest an autosomal dominant pattern, which means one changed copy of a gene is enough. GARD doesn't name the gene.
