Cancer is a disease, which involves abnormal cell growth. It is caused due to mutation in cells. The cell undergoes uncontrolled division. It has the potential to invade or spread to other parts of the body. Based on the type of tumors, cancer is benign and malignant and from origin it is of different types. Along with humans, cancer is also spread to the animals. They also contain different types based on the origin. Cancer is rife in the animal kingdom. For many, the mortality rate is similar to that suffered by humans. The tumor suppressor gene (p53) will helps to supress the cancer genes in humans along with in animals. Cancer is also prevalent in wild animals. Elephants have less chance to effect because they contain trillion of cells. The incidence of cancer in humans is much higher than the incidence of cancer in elephants and whales called as “Peto's paradox”.
