Cancer comes in two forms. It can comprise tissues that are either hard or liquid-filled. They are abnormal in the sense that they are tissues found in the wrong places. Tumors can be classified as either malignant or benign. Benign tumors are the swellings that grow but do not extend to other sections of the body, meaning that, if they grow on one spot, they remain there. Therefore, benign tumors are not cancerous in nature since they do not grow back once they are removed (Broughton, 2012, p. 1609). Malignant tumors can be identified by their characteristic nature of infecting other cells in the body and converting them to bear their characteristics. Benign tumors rarely lead to death unless they develop and/or inhibit the functions of an organ in the body. On the contrary, malignant tumors have a high potential of leading to death. Treatment of tumors happens in different ways depending on the type of tumor and/or its location (Broughton, 2012, p. 1610). Most benign tumors are usually cut as a way of removing them, similar to some malignant tumors, which are cut and/or treated using chemotherapy and radiotherapy as a way of killing the infected surrounding cells.
