Final answer:
The correct answer is 'C) Spread to distant organs'. Metastasis involves cancer cells spreading from the primary tumour to other parts of the body, leading to new tumour growth in those locations, which is associated with a poorer prognosis.
Step-by-step explanation:
The consequences for tumours that metastasize are that these cancerous cells can spread and grow in distant organs of the body, leading to new tumour formation far from the original tumour's location. Metastasis results in disseminated cancer, often causing severe complications and is associated with a poor prognosis. Cancers that have metastasized are typically harder to treat and are responsible for the majority of cancer deaths. Different types of cancers have a propensity to spread to specific organs, such as the brain, lungs, bones, and liver.
For the student's question, the correct answer would be 'C) Spread to distant organs', as metastasis refers to the process where cancer cells break away from a primary tumour and travel through the bloodstream or lymphatic system to form new, secondary tumours in other parts of the body.
