The correct Answer is:
To solve the question, we need to evaluate the three statements provided: 1. **Statement P**: "Metastasis is not the property of benign tumours." 2. **Statement Q**: "Cancer cannot be induced by chemical agents." 3. **Statement R**: "Biopsy and histopathological studies are important tools for the diagnosis of cancer." ### Step-by-Step Solution: **Step 1: Analyze Statement P** - Metastasis refers to the spread of cancer cells from the original site to other parts of the body. - Benign tumors do not spread; they remain localized and do not invade surrounding tissues or metastasize. - Therefore, **Statement P is correct**. **Step 2: Analyze Statement Q** - Cancer can indeed be induced by various agents, including chemical agents known as carcinogens (e.g., tobacco, certain chemicals). - Since cancer can be caused by these agents, **Statement Q is incorrect**. **Step 3: Analyze Statement R** - Biopsy involves taking a sample of tissue to examine it microscopically for signs of cancer. - Histopathological studies are crucial for diagnosing cancer as they help identify abnormal cell growth. - Therefore, **Statement R is correct**. ### Conclusion: - The correct statements are P and R. - The incorrect statement is Q. Thus, the answer is that the set of correct statements is **P and R**.
