Answer

To solve the question regarding the treatment of most cancers, we will analyze the three options provided: Surgery, Radiotherapy, and Chemotherapy.

### Step-by-Step Solution:

1. **Understanding Surgery**:
- Surgery involves the physical removal of cancerous tissues from the body. It is often one of the first lines of treatment for localized cancers where the tumor can be completely excised.
- **Conclusion**: Surgery is a valid method of cancer treatment.

2. **Understanding Radiotherapy**:
- Radiotherapy uses high doses of radiation to kill cancer cells or shrink tumors. It is often used when the cancer is not entirely removable by surgery or to target cancer cells that may remain after surgery.
- **Conclusion**: Radiotherapy is also a valid method of cancer treatment.

3. **Understanding Chemotherapy**:
- Chemotherapy involves the use of drugs to kill cancer cells. It can be used to treat cancer that has spread or to shrink tumors before surgery (neoadjuvant chemotherapy) or to eliminate remaining cancer cells after surgery (adjuvant chemotherapy).
- **Conclusion**: Chemotherapy is another valid method of cancer treatment.

4. **Combining Treatments**:
- Most cancers are treated using a combination of these methods (surgery, radiotherapy, and chemotherapy). This multi-modal approach increases the chances of effectively treating the cancer and reducing the risk of recurrence.
- **Final Conclusion**: The correct answer is that most cancers are treated by a combination of Surgery, Radiotherapy, and Chemotherapy.

### Final Answer:
The correct answer is (a) Surgery, (b) Radiotherapy, and (c) Chemotherapy.
