Identify the incorrect pair.

Options

A. Melanomas - Cancer of melanocytes
B. Lipomas - Cancer of lymphoid tissues
C. Myomas - Cancer of muscles
D. Leukemias - Cancer of blood cells

Answer

To identify the incorrect pair from the given options regarding types of cancer, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Melanomas**:
- Melanomas are a type of skin cancer that originates in melanocytes, the cells responsible for producing melanin (the pigment that gives color to the skin).
- They are known for their rapid spread and are classified as malignant melanoma.
- **Conclusion**: This is a correct pair (Melanomas - Skin Cancer).

2. **Analyzing Lipomas**:
- Lipomas are benign tumors made up of fatty tissue and are found under the skin.
- They are not cancerous and grow slowly, forming soft lumps.
- **Conclusion**: This is an incorrect pair (Lipomas - Cancer of Lymphoid Tissue). Lipomas are not cancers; they are benign tumors.

3. **Examining Myomas**:
- Myomas, also known as fibroids, are tumors that grow from muscle tissue, primarily found in the uterus.
- They are classified as muscle tumors.
- **Conclusion**: This is a correct pair (Myomas - Muscle Cancer).

4. **Reviewing Leukemia**:
- Leukemia is a type of cancer that affects blood cells, particularly white blood cells (WBCs), and involves the bone marrow.
- It leads to an increased number of WBCs, which can impair the body's ability to fight infections.
- **Conclusion**: This is a correct pair (Leukemia - Cancer of Blood Cells).

### Final Conclusion:
The incorrect pair is **Lipomas - Cancer of Lymphoid Tissue**. Lipomas are not a type of cancer; they are benign fatty tumors.
