Which one of the following statements is correct?

Options

A. Patients, who had undergone surgery, are given cannibinoids to relieve pain
B. Benign tumours show the property of metastasis
C. Heroin accelerates body functions
D. Malignant tumours may exhibit metastasis

Answer

To determine which statement is correct among the given options, let's analyze each one step by step:

1. **Statement Analysis**:
- **Option 1**: "Patients who have undergone surgery are given cannabinoids to relieve pain."
- Cannabinoids are substances derived from the cannabis plant. While they may have some analgesic properties, they are primarily known as hallucinogens, which alter perception and can lead to false imaginations. They are not typically used as primary pain relievers post-surgery. Instead, opioids are more commonly prescribed for pain relief.
- **Conclusion**: This statement is incorrect.

2. **Option 2**: "Benign tumors show the property of metastasis."
- Tumors are classified as benign or malignant based on their behavior. Benign tumors do not spread to other parts of the body; they remain localized. In contrast, malignant tumors have the ability to metastasize, meaning they can spread to other organs and tissues.
- **Conclusion**: This statement is incorrect.

3. **Option 3**: "Heroin accelerates body function."
- Heroin is an opioid that depresses the central nervous system. It does not accelerate body functions; rather, it slows them down, leading to decreased heart rate and blood pressure.
- **Conclusion**: This statement is incorrect.

4. **Option 4**: "Malignant tumors may exhibit metastasis."
- Malignant tumors are characterized by their ability to invade surrounding tissues and spread to distant sites in the body. This process is known as metastasis. Therefore, this statement is true.
- **Conclusion**: This statement is correct.

**Final Answer**: The correct statement is: "Malignant tumors may exhibit metastasis."
