Cancer cells no longer have programmed cell death, known as ______________.
Complete the following statement. Proteases can do all of the following to promote cancer development and metastasis EXCEPT:
Stimulate growth factors.
Build the basement membrane.
Destroy extracellular matrix (ECM).
The formation of blood vessels surrounding a tumor is known as ______________.
If cancer originates in one lobe of the lungs and then metastasizes to the adrenal glands and then the liver, what kind of cancer is it?
What is the main site of metastasis for breast cancer?
Which of the following allows tumor cells to select certain tissues over others during metastasis?

Which of the following cancers is least likely to metastasize?
Which of the following inhibits angiogenesis?
Which of the following is NOT a typical way that cancer metastasizes?
In the blood
In the lymphatic system
Through body walls
Via the gastrointestinal tract
Which of the following stimulates angiogenesis?
Why is the prediction of cancer metastasis so hard to determine in the lymphatic system?
Everyone has slightly different lymphatic networks.
More cells are found in lymph than in blood, making it hard to spot cancer cells.

In an animal model
In a single concentration
At high rates of speed
Hormone replacement therapy has been link to increased ______________ cancer.
