Cancers are a
serious problem in the Bernese and a common cause of early death. Since 1990 the BMDCA
and Bernergarde have sponsored studies of these diseases in our breed. The
results are summarized below.
- Approximately 50% of Berners die from cancer.
- The average age at which cancer is diagnosed is 6.21 years; however, this varies widely.
- The most common types of cancer found in Berners are:
- histiocytosis (24.0% of cases): these tumors are
inherited, but probably through the action of many genes (polygenic) acting together
- mastocytoma: also inherited
- lymphosarcoma: not inherited
- fibrosarcoma: not inherited
- osteosarcoma: no conclusions yet as to heritability.
Several cancer studies in Bernese are ongoing and need a
variety of samples from both affected and healthy dogs. See the
Bernergarde health studies page for a complete list.
