The inflammatory response is a defense mechanism that evolved in higher organisms to protect them from infection and injury. In order to deconstruct the roles and the mechanisms of action of inflammation and cancer, it is important to understand how inflammation in cancer is induced and maintained in the first place, both in terms of time and stimulus ().Around 15%-20% of all cancer cases are preceded by infection, chronic inflammation, or autoimmunity at the same tissue or organ site (Grivennikov et al., 2010 . Inflammation can be caused by a number of factors that can damage cells but is broadly divided into : Physical - can be mechanical as in a car accident injury or assault or environmental like severe cold and heat (burns). Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. Neutrophils are polymorphonuclear and phagocytic leukocytes that comprise the first line of host immune response against invading pathogens ().They are also important effector cells during tissue injury-induced inflammation ().Neutrophils have a high potency and efficacy to sense and eradicate microbial infections, and individuals with a neutrophil deficiency (such as neutropenia . The affected cells release chemicals that aid in removing the cause of harm. A person may feel pain, stiffness, distress, and discomfort, depending on the severity of the inflammation.
