Cancer & Tumors

  • A rat's lifespan is only 18-48 months so ageing changes and natural fatal conditions such as tumours are fairly common.

  • All tissues and organs of the body may develop cancer (an abnormal overgrowth of their constituent cells).

  • Cutaneous (reactive) histiocytosis is an uncommon condition of dogs. The condition is poorly described in the scientific literature and has various grades all of which may be found in one animal.

  • This is a common benign tumour of Langerhans cells. 99% are permanently cured by removing them surgically.

  • Cyclophosphamide is a chemotherapeutic drug used to treat cancer in animals. These drugs can cause cancer in humans and should be handled with caution.

  • Cysts are hollow spaces containing liquid or solidified secretion. A few cysts form within cancers but only non-cancerous cysts are considered here.

  • Muscle (called smooth muscle) and fibrous connective tissues form the framework (stroma) that holds other tissues together in the organs of the body. A number of different tumours can develop from the cells of these tissues.

  • Doxorubicin is a chemotherapeutic drug used to treat cancer in animals. These drugs can cause cancer in humans and should be handled with extreme caution.

  • These tumours are polyp-like growths with a narrow base or a stalk. Some are nodular overgrowths secondary to inflammation but others are benign or malignant cancers of the glands found in this area.

  • Tumours of the cortex of the adrenal glands may be overgrowths (hyperplasias) or benign (non-spreading) or malignant (spreading) cancers. Usually they are producing hormones that will have secondary clinical effects elsewhere in the body.
