Question

Answer

Malignant tumour first grows slowly. No symptoms are noticed. This stage is called the latent stage. The tumour later grows quickly. The cancer cells go beyond adjacent tissue and enter the blood and lymph.

•Once this happens, they migrate to many other sites in the body, where the cancer cells continue to divide. It is metatasis. Only malignant tumours are properly designated as cancer.

Answer

C option is correct because malignant tumor itself means that the tumor that is moving in body and so this condition is called metastasis

Answer

Explanation:
Malignant tumors are cancerous tumors that have the ability to invade nearby tissues and spread to other parts of the body. This spread of cancer cells from the original site to other parts of the body is called metastasis. Therefore, the correct statement is option C - Malignant tumors may exhibit metastasis.

Here is a detailed explanation of each statement:

a) Benign tumors show the property of metastasis:
- This statement is incorrect.
- Benign tumors are non-cancerous tumors that do not invade nearby tissues or spread to other parts of the body.
- They grow slowly and are usually localized to one area.
- Unlike malignant tumors, benign tumors do not exhibit metastasis.

b) Heroin accelerates body functions:
- This statement is incorrect.
- Heroin is an illegal and highly addictive opioid drug that depresses the central nervous system.
- It slows down body functions, including breathing and heart rate, rather than accelerating them.

c) Malignant tumors may exhibit metastasis:
- This statement is correct.
- Malignant tumors are cancerous tumors that have the ability to invade nearby tissues and spread to other parts of the body.
- Cancer cells can break away from the primary tumor, enter the bloodstream or lymphatic system, and establish secondary tumors in other organs or tissues.
- This spread of cancer cells is known as metastasis and is a hallmark of malignant tumors.

d) Patients who have undergone surgery are given cannabinoids to relieve pain:
- This statement is incorrect.
- Cannabinoids, which are compounds found in marijuana, have been investigated for their potential analgesic properties.
- However, the use of cannabinoids for pain relief is still controversial and not widely accepted in medical practice.
- There are other well-established analgesic medications and techniques available for post-surgical pain management.

In summary, the correct statement is option C - Malignant tumors may exhibit metastasis. Malignant tumors have the ability to invade nearby tissues and spread to other parts of the body, while benign tumors do not exhibit metastasis.
