Which treatment is most commonly used for malignant tumors of the skin and other areas?

1. Surgery

2. Chemotherapy

3. Radiation

4. Herbal supplements

The correct answer is: Surgery

Surgery is the most common treatment for malignant tumors of the skin and other areas because it aims to remove the tumor and surrounding tissue to ensure all cancerous cells are excised. This approach is often preferred for solid tumors where the cancer has not widely spread, making it possible to achieve complete removal. Surgical procedures can vary in scope, from minor excisions to more extensive resections, depending on the size and location of the tumor. While chemotherapy and radiation are important treatment modalities for cancer, they are typically used in cases where the cancer has metastasized (spread) or where surgery is not feasible. Chemotherapy employs drugs to kill cancer cells and is often used for systemic treatment, while radiation therapy uses high-energy rays to target and destroy cancer cells. Both treatments may be integrated into a comprehensive care plan, but surgery remains the frontline approach for localized cancers, particularly in the skin, where early intervention can be highly effective. Herbal supplements, although they may be sought by some patients for various health benefits, are not recognized as an effective treatment for malignant tumors and should not replace conventional cancer therapies. Their efficacy in treating cancer is unproven and lacks scientific validation.
