Level#1

Cancer is the second leading cause of death in the United States. Cancer causes the body's cells to grow abnormally and at an unusually fast pace. Scientists do not know all the causes of cancer. But, studies have shown that contact with substances called carcinogens raises a person's risk of getting cancer. Carcinogens are cancer-causing substances. Tobacco, for example, contains carcinogens. Tobacco causes lung, throat, and mouth cancer.

1. What is the second leading cause of death in the United States?





2. What does cancer do to the cells of the body?





3. What do scientists not know about cancer?

But, studies have shown that contact with substances called carcinogens raises a person's risk of getting cancer. Carcinogens are cancer-causing substances. Tobacco, for example, contains carcinogens. Tobacco causes lung, throat, and mouth cancer. Sometimes, cancer cells gather together into a clump, or tumor. These tumors can be either benign or malignant. Benign tumors do not spread to other organs. Malignant tumors can be harmful. They spread to other parts of the body and can damage important organs. Benign tumors are less of a health risk than malignant tumors.
