Show transcript
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
