Question is based on the following passage. Cancer is one of the leading causes of death in our society. Cancer is a disease in which a cell in the body loses its sensitivity to factors which regulate cell growth and division. The cell begins to multiply without restriction, creating a growing mass called a tumor, which interferes with the structure and functioning of the organ in which it is located. Frequently, cancer cells become metastatic, meaning that they travel, settling in a number of places and giving rise to secondary tumors. Much of medical research is devoted to finding ways of preventing, controlling, and curing cancer. Because of the metastatic trait of cancer cells, how can we judge a cancer treatment to be effective? A. if the original-source tumor has been identified B. if the entire body has been proven free of tumors over a period of time C. if the highest possible levels of treatment have been used D. if the complete tumor is removed E. if no new cancer cells are found in 2 weeks
