CANCER AND TUMOR

The uncontrollable cell division results in the formation of a new growth which is commonly known as Tumor. Medically it is termed neoplasm. Human immune system has the power to find these neoplastic cells and it has the potential to destroy it. Some of these cells can escape from the immune system and later it develops malignancy thereby leading to cancer. The first diagnostic step in any kind of cancer treatment is the determination of the nature of the tumor. Tumors are classified into two types. It may be either Benign or malignant. Benign tumors can never become a cancer. It has a slow growth and it cannot really influence the nearby tissues and it can never really be a threat. Once if the benign tumor is removed, it can come again. On the other hand, malignant tumor is termed cancer. This tumor usually invades the nearby tissues and spreads all over the body. Even after the removal of these malignant tumors, the traces that are left would eventually bring back the cancer once again. In the early stages, malignant tumors have a very little potential to spread. This is the pure reason why cancer can be completely cured if shown in early stages.
