Answer

To determine which of the options is used for the treatment of cancer, we need to analyze each option provided:

1. **Tetracycline**: This is an antibiotic that is primarily used to treat bacterial infections. It is not used for cancer treatment.

2. **TSH (Thyroid Stimulating Hormone)**: TSH is a hormone that stimulates the thyroid gland to produce thyroid hormones. It is not directly used in cancer treatment.

3. **Insulin**: Insulin is a hormone that regulates blood sugar levels in the body. It is not used for cancer treatment.

4. **HGH (Human Growth Hormone)**: HGH is involved in growth and development. While it may have some applications in certain types of cancer, it is not primarily known as a treatment for cancer.

Upon reviewing the options, none of them are standard treatments for cancer. However, the video transcript mentions that HGH is useful in the treatment of breast cancer, which suggests that it could be the most relevant option among those listed.

**Conclusion**: The option that is mentioned as being useful in the treatment of breast cancer is **HGH (Human Growth Hormone)**.
