Lesson details
Key learning points
- Cancer is caused by uncontrolled cell growth and division which can lead to the formation of tumours.
- Not all tumours are cancerous; they can be benign or malignant.
- Benign tumours are usually contained within one area and do not invade surrounding tissues.
- Malignant tumours are cancerous, they invade surrounding tissues and can cause secondary tumours.
- Scientists have identified lifestyle and genetic factors that can increase the risk of developing cancer.
Keywords
