Which of the following statements is true of cancer?

A) If NK-cell activity is uncompromised by stress, cancer progresses slower.
B) Length of survival for cancer patients is independent of NK-cell activity.
C) High NK-cell activity is linked with the development of malignancies.
D) Cancer patients show extremely high NK-cell activity in their blood.

NK-cell Activity

The actions or reactions of natural killer cells, a type of white blood cell that plays a crucial role in the body's immune response by targeting tumor cells and infections.

Malignancies

Refers to the presence of cancerous tumors that can invade and destroy nearby tissue and spread to other parts of the body.

Cancer Patients

Individuals who have been diagnosed with cancer, undergoing treatment for tumor eradication, management of symptoms, or palliative care.

Final Answer :
A
Explanation :
Studies have shown that stress can compromise NK-cell activity, which in turn can lead to faster progression of cancer. Therefore, if NK-cell activity is uncompromised by stress, cancer progresses slower. The other options are incorrect. Length of survival for cancer patients can be influenced by the activity of NK cells. High NK-cell activity is associated with a reduced risk of cancer development. Cancer patients do not necessarily show extremely high NK-cell activity in their blood.
