Practice Questions

1.State what is meant by a tumour.

A tumour is a growth, caused by cell division.

2. What are the two types of tumours?

Benign and malignant.

3.Why are malignant tumours more dangerous than benign tumours?

Malignant tumours will invade neighbouring tissues and spread to different parts of the body using the blood or lymph where they form secondary tumours.

Malignant tumours will replace healthy organ tissue with cancerous tissue. This decreases organ function and if untreated will lead to death.

Benign tumours are growths of abnormal cells which are contained in one area, usually within a membrane.

They will not invade or spread to other parts of the body.
