Point out some Difference between Tumor And Cancer?

Tumor is a swelling or growth because of an abnormal growth of tissue. Tumors can either be benign or malignant. The benign tumor remains highly localized. On the other hand, the malignant tumor known as cancer is characterized by invasiveness and can form distant colonies elsewhere in the body. Cancer cells are very irregular in shape and their arrangement in tumor tissue is very unruly. Cancer is painless if it does not compress the adjacent organs. Later, it causes pain by invading or pressing the adjacent vital organs.

Another aspect of malignancy is the ability of tumor cells to elude the immune system. These cells may cover up antigens that would otherwise mark them for destruction or they may rid themselves of the cell surface molecules that lymphocytes use to recognize foreign cells. The immune system is largely ineffective.
