There are some significant differences between the two kinds of tumor. Each kind of tumor has its own characteristics. Benign tumors cannot spread out to other parts of the body because they are capsulated by a fibrous sheath of connective tissue. Therefore, they remain at their original sites. In contrast, malignant tumors (cancers) are not capsulated, so they have the ability to metastasize through blood and lymphatic vessels in a process called metastasis (1). The result of this process is new masses of the tumor will be created known as metastatic tumors. Another different characteristic is in their size and shape. Benign tumors are typically small and have smooth regular margins almost like normal cells. On the other hand, malignant tumors
