Cancer cells are more easily damaged by radiation than normal cells because they are

Options

A. Starved of mutation
B. Undergoing rapid division
C. Different in structure
D. Non-dividing

Explanation

To answer the question, "Cancer cells are more easily damaged by radiation than normal cells because they are," we need to analyze the options provided and understand the characteristics of cancer cells compared to normal cells.

### Step-by-Step Solution:

1. **Understanding Cancer Cells:**
- Cancer cells are characterized by uncontrolled and abnormal cell division. This means that they divide more frequently and do not respond to the regulatory mechanisms that normally control cell growth and division.

2. **Analyzing the Options:**
- **Option A: Starved of Nutrition**
- This option suggests that cancer cells are lacking nutrition. However, cancer cells often compete with normal cells for nutrients and can actually thrive on the nutrients available in their environment. Therefore, this option is incorrect.

- **Option B: Undergoing Rapid Division**
- Cancer cells are known for their rapid and uncontrolled division. This characteristic makes them more susceptible to damage from radiation, which targets actively dividing cells. Thus, this option is likely correct.

- **Option C: Different in Structure**
- While cancer cells may have structural differences compared to normal cells, this is not the primary reason they are more easily damaged by radiation. The structure itself does not directly correlate with susceptibility to radiation damage. Therefore, this option is incorrect.

- **Option D: Non-Dividing**
- This option is incorrect because cancer cells are continuously dividing. Non-dividing cells would not be affected by radiation as they are not in the process of cell division.

3. **Conclusion:**
- Based on the analysis of the options, the correct answer is **B: Undergoing rapid division**. This is because radiation therapy is particularly effective against cells that are actively dividing, which is a hallmark of cancer cells.

### Final Answer:
**B: Undergoing rapid division**
