Tabacco chewing results in

Options

A. mouth cancer
B. lung cancer
C. bone cancer
D. leukamia

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the health effects of tobacco chewing. We need to identify the specific type of cancer that is associated with this habit.

2. **Identifying Carcinogens**: Tobacco chewing releases approximately 28 cancer-causing chemicals known as carcinogens. These substances can lead to genetic alterations in the cells of the mouth and surrounding areas.

3. **Effects on Oral Tissues**: The carcinogens present in chewing tobacco primarily affect the oral lining, gums, lips, and cheeks. This damage can lead to changes in the cells, increasing the risk of developing cancer in these areas.

4. **Evaluating the Options**:
- **Mouth Cancer**: Given the direct impact of carcinogens on the oral tissues, mouth cancer is a likely result of tobacco chewing.
- **Lung Cancer**: This type of cancer is primarily associated with smoking tobacco, not chewing, making this option incorrect.
- **Bone Cancer**: There is no direct link between tobacco chewing and bone cancer, so this option is also incorrect.
- **Leukemia**: This is a cancer of the blood and is not directly related to tobacco chewing, making this option incorrect as well.

5. **Conclusion**: Based on the evidence and analysis of the options, the correct answer is **mouth cancer**.
