Cancer is considered as a common name to address a large group comprising more than 100 diseases affecting several parts of the body. All cancers show common characteristics such as the uncontrolled growth and proliferation of abnormal cells, infiltrating and spreading to different tissues and organs throughout the body, and destroying the normal cells and tissues. Cancer can begin in the epithelial tissue and is known as carcinomas, and when it begins in the connective or supportive tissue, they are called sarcomas. The blood cancers are known as leukemias, and when it begins in the plasma cells, they are known as myeloma. If the cancer begins in the lymphatic system, they are known as lymphoma, and if the cancer begins in the brain or spinal cord, they are known as cancers of the central nervous system. Cancers at the initial stages are currently considered as curable, and recurrent/metastatic cancers are considered chronic and difficult to manage, and needs multimodal therapies.
