Question 30

[jsfkt78927]

Im kinda disgruntled about accepting "I. Metastasis is a property that distinguishes cancer from non-cancer." as supported in the passage.

The passage in my opinion seems to imply that 'malignant neoplasms' have three defining qualities: 1....ect,2.....ect,3. metastasis. So it doesnt say that if it isn't metastasizing then it isnt CANCER, just maybe it isnt malignant.

Obviously there is however the 2nd to last sentence of the first paragraph that describes a 'unique property' of cancer. It seems like if you choose this to defend option I. then you're taking one sentence out of context from the whole passage. With respect to the beginning of the same paragraph this sentence comes from I would infer that if its not metastasizing then its probably not a malignant cancer, not 'non-cancer'.

This answer just seems silly in the context of the passage.

What do y'all think.

HI there!

The way I understand the passage, it does point to metastasis as a property unique only to cancer. Further, "it is metastasis that in most instances kills the patient and understanding the biology of metastasis is one of the central problems of cancer research."

The rest of the passage further supports this by discussing the mechanism by which cancer cells differ in growth and invade other tissues.

Hope this helps.
