Additional Notes: $\text{{Tumor Name}} = \text{{Tissue Origin}} + \text{{Type of Tissue}} + \text{{Benign/Malignant Suffix}}$

1. Tissue Origin: This describes the tissue from which the tumor originates. Common examples are "Mesenchymal" for connective tissue tumors and "Parenchymal" for glandular and epithelial tissue tumors.

2. Type of Tissue: This specifies the type of tissue where the tumor is found. Examples include "Fibrous tissue," "Fatty tissues," "Cartilage," etc.

3. Benign/Malignant Suffix: The suffix helps classify the tumor as either benign or malignant. Common suffixes include:

   • -oma: Used for benign tumors. For example, "Fibroma" for benign tumors of fibrous tissue.
   • -sarcoma: Used for malignant tumors of mesenchymal origin. For example, "Osteosarcoma" for malignant tumors of bone.
   • -carcinoma: Used for malignant tumors of epithelial cell origin. For example, "Adenocarcinoma" for malignant tumors of glandular tissue.

Putting it together, you might have:

• Fibroma:

  • Tissue Origin: Mesenchymal
  • Type of Tissue: Fibrous tissue
  • Suffix: -oma (indicating it's benign)

• Osteosarcoma:

  • Tissue Origin: Mesenchymal
  • Type of Tissue: Bones
  • Suffix: -sarcoma (indicating it's malignant)
