A tumor also known as a neoplasm is an abnormal growth of tissue or a swelling in the part of the body without any inflammation. A tumor does not necessarily mean cancer. It can be benign, pre-malignant or malignant. The word tumor originates from the Latin word’ tumere’ meaning to swell. Cells divide and grow in the body and are frequently replaced by newer ones. The growth of cells and their division is controlled. When the body fails to replace the damaged cells it disturbs the balance thereby causing a tumor. A tumor is termed as malignant when it is cancerous which means there are several secondary growths that have evolved affecting vital parts of the body.
