Sarcomas are less common than carcinomas and are typically categorized into:
1. Bone sarcomas: E.g., osteosarcoma.
2. Soft tissue sarcomas:
E.g., liposarcoma, leiomyosarcoma. Early detection improves treatment outcomes.
Step 1: Definition of sarcoma. Sarcoma is a type of cancer that originates in connective tissues such as bones, muscles, fat, cartilage, and blood vessels. These tissues provide structural and functional support to the body.
Step 2: Comparison with other options. - Option \( (A) \): Plasma cell cancers, such as multiple myeloma, are not sarcomas.
- Option \( (B) \): Glandular cancers, such as adenocarcinomas, originate in epithelial tissues of glands.
- Option \( (D) \): Epithelial cancers, called carcinomas, originate in the epithelium, not connective tissues.
Conclusion. Sarcoma specifically refers to cancers arising from connective tissues, making \( (C) \) the correct answer.
