149
What does mestatasis refer to?
The development of secondary malignant growths at a distance from a primary site of cancer.
150
When do cancer cells develop?
When the DNA of normal cells is damaged, mutations are produced that affect the orderly, controlled process.

Because what may be low intensity to one client will be high intensity to another.
158
What is a health deficiency risk of chemotherapy and/or radiation that should be taken into account by a physician/PT?
That the client may be anemic due to the chemo/radiation and therefore require reduced exercise intensity or weight-bearing activities.
