Living with Collecting duct carcinoma

A rare, aggressive kidney cancer that often has no early symptoms and tends to affect younger adults.

Understanding Collecting duct carcinoma

Collecting duct carcinoma (CDC) is a rare and aggressive kidney cancer that begins in the kidney's collecting ducts.

Many people have no symptoms until the cancer is advanced. It can affect people of all ages but tends to occur in younger patients. It usually occurs in people with no family history of the condition.

Signs & symptoms

Symptoms vary from person to person. GARD lists these as possible symptoms:

  • Flank pain
  • Unexplained weight loss
  • Blood in the urine
  • Often no symptoms until the cancer is advanced

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