Question
Chapter 16, Problem 16PDQ
Summary Introduction
To review:
The percentage of money that should be devoted to research and education on preventing cancer rather than on finding a cure.
Introduction:
Research has revealed that 90–95% of cancer is developed due to environmental factors and the lifestyle. Only 5–10% of cases of cancer are due to genetic factors. Once the root cause of cancer development is known and confirmed, money should be spent on education and awareness for preventing cancer.

Cancer can arise spontaneously, but it can also be induced as a result of environmental factors such as sun exposure, infections, and tobacco smoking. If you were asked to help allocate resources to cancer research, what emphasis would you place on research to find cancer cures, compared to that placed on education about cancer prevention?
Why are people more likely to develop cancer as they age? Why does inheriting a mutation increase cancer risk?
What would make someone think they might have developed cancer and seek medical testing?
What steps or procedures are involved in your choice of medical imagining?
How does the technology prove or suggest that a patient may have cancer? How accurate is the test?

- Which of the following statements about cancer is false? (a) oncogenes arise from mutations in proto-oncogenes (b) tumor suppressor genes normally interact with growth-inhibiting factors to block cell division (c) more than 120 cancer-driving genes have been discovered (d) oncogenes were first discovered in mouse models for cancer (e) the development of cancer is usually a multistep process involving both oncogenes and mutated tumor suppressor genesarrow_forwardEvery year, about a million Americans are diagnosed with cancer. This means that about 75 million Americans now living will eventually have cancer, And one in five will die of the disease. There are many kinds of cancers and many causes, such as smoking, overexposure to ultraviolet rays, a high fat and low fiber diet, and some workplace chemicals. Hundreds of millions of dollars are spent each year on searching for treatment, yet less money is spent on prevention. Should we devote more resources to treating cancer or to preventing it? Explain.arrow_forwardWe know that there are several risk factors for cancer, which of those risk factors are significant for a 52 year old white male?
