Breast cancer is an example of:

Options

A. A sarcoma
B. Carcinoma
C. Communicable
D. Contagious

Answer

**Step-by-Step Solution:**

1. **Understanding the Types of Cancer:**
- The question asks about breast cancer and its classification. We need to identify the type of cancer breast cancer falls under.

2. **Analyzing the Options:**
- The options provided are:
- Sarcoma
- Carcinoma
- Communicable
- Contagious

3. **Defining Sarcoma:**
- Sarcoma is a type of cancer that originates in connective tissues such as bones, muscles, and fat. Since breast cancer does not originate from these tissues, this option can be eliminated.

4. **Defining Carcinoma:**
- Carcinoma is the most common type of cancer and begins in epithelial tissues, which are the tissues that line the surfaces of organs and structures throughout the body. Breast cancer typically starts in the ducts that carry milk to the nipple, which are epithelial tissues. Therefore, this option is a strong candidate.

5. **Defining Communicable and Contagious Diseases:**
- Communicable diseases are those that can spread from one person to another, often through pathogens. Contagious diseases are a subset of communicable diseases that spread through direct contact or airborne means. Breast cancer does not spread in this manner, so these options can also be eliminated.

6. **Conclusion:**
- Based on the definitions and the origin of breast cancer, the correct classification for breast cancer is carcinoma.

**Final Answer:**
Breast cancer is an example of carcinoma.
