Understand the term 'metastasis': In the context of cancer, metastasis refers to the process by which cancer cells spread from the original site to other parts of the body.
Differentiate metastasis from other cancer-related processes: Metastasis is distinct from the mutation of normal cells into cancerous cells, which is the initial step in cancer development.
Recognize the initial formation of a tumor: This occurs at the primary site and is not the same as metastasis, which involves the spread of cancer cells.
Identify programmed cell death: Known as apoptosis, this is a natural process that can occur in cancer cells but is not related to metastasis.
Summarize the concept: Metastasis is a critical aspect of cancer progression, involving the movement and establishment of cancer cells in new locations within the body.
