Which one of the following statements is correct?
A
Malignant tumours may exhibit metastasis
B
Patients who have undergone surgery are given cannabinoids to relieve pain
C
Benign tumours show the property of metastasis
D
Heroin accelerates body functions
Detailed Solution
Malignant tumours are masses of proliferating neoplastic cells that grow rapidly and invade surrounding tissues; cells sloughed from them reach distant sites through blood and start new tumours. This property, called metastasis, is the most feared property of malignant tumours. So the statement is correct.
Benign tumours normally remain confined to their original location and do not spread to other parts of the body.
The pain killer given to patients after surgery is morphine (an opioid), not cannabinoids.
Heroin is a depressant and slows down body functions.
Hence the correct statement is that malignant tumours may exhibit metastasis.
