Tumors in Hamsters

Updated November 21, 2016

Hamsters have relatively short lifespans, living on average 2 to 3 years. Like humans, hamsters are more susceptible to age-related diseases such as cancer as they mature. Tumours are quite common in elderly hamsters.

Types

Tumours can be located internally, such as in the bladder, or externally, appearing as a lump on the skin. All tumours can be either benign or malignant.

Identification

The presence of tumours in hamsters often is accompanied by loss of appetite, lethargy, weight loss, change in personality and sometimes hair loss or bleeding sores.

Considerations

Female hamsters are more prone to developing internal, cancerous tumours due to their complex reproductive systems, according to PopularPets.net.

Theories and Speculation

The most common areas in which hamsters develop tumours appear to be on the skin and within the thyroid and adrenal glands, according to Ask-The-Vet.com.

Expert Insight

According to the Animal Health Center, there is a chance that a skilled veterinarian can surgically remove small external tumours. Internal tumours are less likely to be treated with surgery.
