You are caring for a client who has just been told that they have stage IV colon cancer. The client asks you what ""stage IV"" means. What would be your best response?

Stage IV - There is a primary tumor, lymph node involvement and metastases.

Explanation:

Staging is the extent of spread of tumor within the patient.

The American Joint Committee on Cancer (AJCC) divides all cancers into Stages 0 - IV, incorporating into each stage several TNM (tumor/node/metastasis) stages usually with the same prognosis.  

Staging is essential in determining the patient prognosis.

The approximate 5-year survival rate for colorectal cancer patients of all stages is 64.4% (In the United States) and survival is inversely related to stage.

Surgery usually provides the only curative option for patients diagnosed with Stage IV colon cancer.

explanation:

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
