A Level Biology Revision (Year 13) "Benign and Malignant Tumours"

In this video, we look at benign and malignant tumours. First we look at benign tumours. We describe what is meant by a benign tumour and the features of benign tumours. We then look at what is meant by a malignant tumour and how malignant tumours are defined as cancers. We look at how malignant tumours can spread via metastasis and how malignant tumours can be treated by chemotherapy and radiotherapy. Image credits: Mitosis https://commons.wikimedia.org/wiki/Fi...
