To solve the assertion and reason question regarding alpha-interferon and its role in cancer treatment, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Assertion**:
- The assertion states that "alpha-interferon is given to cancer patients which helps in destroying the tumor."
- This statement is true. Alpha-interferon is indeed used in cancer therapy as it has properties that can aid in tumor destruction.

2. **Understand the Reason**:
- The reason states that "alpha-interferon is a biological response modifier, which activates the immune system and helps in destroying the tumor."
- This statement is also true. Alpha-interferon acts as a signaling protein that enhances the immune response, allowing the body to better target and destroy cancer cells.

3. **Evaluate the Relationship**:
