Question

Which of the following best defines cancer?

Options

• A disease characterised by uncontrolled and abnormal division of body cells due to loss of normal growth regulation

• A disease characterised by controlled division of body cells with maintained growth regulation

• A disease involving only the formation of benign tumours that remain localised

• A disease characterised by slow division of epithelial cells with proper contact inhibition

Answer 1

Cancer is fundamentally defined as a disease marked by abnormal and uncontrolled cell division resulting from the loss of normal growth regulation mechanisms. This uncontrolled division leads to the formation of an abnormal mass of cells called a neoplasm or tumour, which distinguishes cancer from normal cellular processes.
