Errors in cell division and cancer: beyond the basics
You can describe cancer including benign and malignant tumours and explain how mutations can cause cancer.
Errors in cell division and cancer: beyond the basics
You can describe cancer including benign and malignant tumours and explain how mutations can cause cancer.
Lesson details
Key learning points
- Cancer is caused by uncontrolled cell growth and division which can lead to the formation of tumours.
- 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.
- Mutations can cause changes in DNA; this alters the nucleotide sequence and genetic code
Common misconception
All tumours are cancerous and dangerous.
Students 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.
Keywords
Mutation - A change in the nucleotide sequence of DNA that can cause mutated genes.

Tumour - A mass of cells that has been produced through uncontrolled cell division.
