Answer: B) Uncontrolled cell growth.
Explanation: Cancer is a disorder that is mainly characterized by uncontrolled cell growth, resulting in numerous other health complications that can eventually cause death. Though cancer can be caused by genetic mutations, it can also be caused by changes in gene expression, so mutations aren't always associated with cancer.
Inflammation of the skin is caused by an immune response. Though cancerous tumors may result in the skin appearing inflated, this is caused by the overgrowth of cells rather than the body's immune response kicking in. In addition, since cancer cells are the body's own cells, they don't trigger the body's immune response like a foreign pathogen would. Thus, inflammation of the skin is not associated with cancer.
As stated previously, cancer is caused by a mutation or changes in gene expression resulting in the body's cells reproducing uncontrollably. Cancer is not caused by a bacterial infection.
