Why Do Dogs Get Cancer? Understanding Causes and Prevention

Cancer is a leading cause of death in dogs, much like in humans. Understanding why dogs get cancer and how to prevent it can help pet owners protect their furry friends and improve their quality of life.

Common Causes of Cancer in Dogs

Cause	Description
Genetic Predisposition	Some dog breeds are more prone to certain types of cancer due to inherited genes.
Environmental Factors	Exposure to toxins, chemicals, and radiation can increase cancer risk.
Age	Older dogs have a higher risk as cancer often develops over time.
Diet and Obesity	Poor nutrition and obesity can weaken the immune system and promote cancer growth.
Viral Infections	Certain viruses have been linked to cancer development in dogs.

How Cancer Develops in Dogs

Cancer occurs when cells in the body begin to grow uncontrollably, forming tumors that can be benign or malignant. Malignant tumors can invade nearby tissues and spread to other parts of the body (metastasis).
