What are the two types of tumour (neoplasm)?
Benign and malignant
What is the defining characteristic of benign tumours?

What is malignancy?
A fundamental property of cancer whereby cells invade other tissues (metastasis) and are able to grow into secondary tumours
What is the most common type of cancer of both sexes respectively?
Men - Prostate
Women - Breast
Why is tumour classification important?
Important in understanding tumour behaviour and can help determine the outcome and therapy required
