Which of the following statements best describes how all cancers are similar and how they can differ?

• A. All cancers involve uncontrolled cell division, but they can differ in the tissues they originate from and the specific genetic mutations involved.
• B. All cancers result from immune system failure and differ only in their rate of metastasis.
• C. All cancers are caused by viral infections and differ only in the age group they affect.
• D. All cancers are inherited genetically and differ in their response to antibiotics.

Answer: (A)

Verified step by step guidance

1. Understand the definition of cancer: Cancer is a group of diseases characterized by uncontrolled cell division, which can lead to the formation of tumors and potentially spread to other parts of the body (metastasis).
2. Identify the commonality among all cancers: All cancers share the fundamental characteristic of uncontrolled cell division, which disrupts normal tissue function.
3. Recognize the differences among cancers: Cancers can differ based on the tissue or organ they originate from, as well as the specific genetic mutations or environmental factors that contribute to their development.
4. Evaluate the incorrect options: For example, not all cancers are caused by immune system failure, viral infections, or inherited genetically. Additionally, antibiotics are ineffective against cancer because they target bacteria, not abnormal cell growth.
5. Select the correct statement: The correct answer is the one that accurately describes the shared characteristic of uncontrolled cell division and acknowledges the differences in tissue origin and genetic mutations.
