In the United States, the average life span of cancer patients, that is the life span from being diagnosed with cancer to death is 7 years, while the average life span of cancer patients in Asia is only 4 years. Therefore, the United States has a higher level of medical care in extending the lifespan of cancer patients than Asia.
On the whole, the United States' awareness of self-care is higher than that of Asians, so the early diagnosis rate of cancer patients in the United States is higher than that in Asia is true and will weaken the above argument most.
