Which of the ONE following characteristic is usually NOT TRUE of cancer cells and the tumors that result? (i.e. all of the answers below are correct except for one-- select the incorrect answer!) Cancer cells do not migrate within the body. Cancer is usually caused by multiple acquired mutations. Cancer cells evolve over time--becoming more potent and more deadly. Cancer cells have dysregulated (uncontrolled) cell division activity. Some cancers are preventable. Question 9 (4 points) Which of the following of...

With regard to cancer, which of the following is FALSE? Cancer can occur in nearly every part of the body. Rates of cancer have increased steadily since the 1930’s and continue to do so today. Cancer is characterized by uncontrolled cell replication. One way cancer can cause death is by disrupting the chemical balance in the body.
