Question

Which of the following is a characteristic of malignant tumours?

विकल्प

• Grows slowly and remains confined to its original site

• Grows usually rapidly and uncontrolled, invades nearby tissues and spreads to distant organs

• Has well-defined boundaries and remains non-invasive

• Never causes metastasis or secondary tumours

Answer 1

Malignant tumours are characterised by rapid, uncontrolled growth with the ability to invade surrounding tissues and spread to distant organs through metastasis. They typically have irregular and invasive boundaries, making them far more dangerous than benign tumours due to their capacity for systemic dissemination.
