Which of the following is drug produced by genetic engineering and is used in the treatment of cancer ?

Options

A. Alpha- interferon
B. Human growth hormone
C. Insulin
D. Calcitonin

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a drug that is produced by genetic engineering and is specifically used in the treatment of cancer.

2. **Analyzing the Options**:
- **Option 1: Alpha Interferon**: This drug is indeed produced through genetic engineering and is used in the treatment of various cancers, including kidney cancer, melanoma, and carcinoid tumors. Therefore, this option is a strong candidate.

- **Option 2: Human Growth Hormone**: This hormone is not primarily used for cancer treatment. It plays a role in regulating body composition, fluids, and growth. Hence, this option is incorrect.

- **Option 3: Insulin**: Insulin is used to manage blood sugar levels in diabetic patients and is not related to cancer treatment. Thus, this option is also incorrect.

- **Option 4: Calcitonin**: This hormone is involved in regulating calcium levels in the blood and is not used for cancer treatment. Therefore, this option is incorrect as well.

3. **Conclusion**: After analyzing all the options, the only drug that fits the criteria of being produced by genetic engineering and used in cancer treatment is **Alpha Interferon**.

**Final Answer**: Alpha Interferon
