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

Benign - A tumour that is non-cancerous and contained to one area.

Common misconception
Pupils may think that all tumours are cancerous and dangerous.
Pupils are given very clear examples of the difference between benign and malignant tumours. The difference between the two is covered in the slide deck, check for understanding questions and practice tasks.
