Abstract
Cancer continues to represent the largest cause of mortality and the major public health problem in most parts of the world although, it can be easily managed if it is diagnosed early especially if there is periodic surveillance but, it is usually discovered too late so, the treatment is multimodal and requires surgery, radiotherapy and chemotherapy which has many side effects. Cancer has many

It has the advantage of rapid growth rate and easy tumor palpation and caliper measurement in the subcutenous location
