Identify at least four kinds of cancer screening tests about which you think people will be more likely to call.
Why do you think people will call about some tests more than others?
People will always be more willing to get the less invasive screenings. Colonoscopies aren't pleasant, and people will be less likely to get them unless awareness is raised. The same goes for prostate cancer screenings. This is, of course, precisely why these awareness campaigns are so important.
As mentioned, breast cancer gets a lot of attention. Because it can be cured, people will be more likely to try to raise the concern of the public. Colon cancer is also a form of cancer that can be cured when caught early. There is also a great deal of concern with regard to skin cancer, especially with the Baby Boomers, since they roasted in the sun and never thought of using sunblock. There was no such thing. An increase in knowledge of symptoms, and dangerous behaviors that can cause a threat, will increase a change one's level of concern/attention to detail.
I have always loved the idea of the monthly breast cancer check (there was even a movement on commercials which called women together to remind each other). Outside of that, I do not think that people simply go to the doctor to have a cancer "check." Instead, they go for other complications and cancer may be part of the evaluation (if the patient is presenting certain symptoms). Outside of that, I would think that a person who believes they may have cancer would be willing to have any tests needed in order to find out (very assumptive on my part).
In accord with the previous post, skin cancer is also one about which many have become aware. Prompt treatment is essential and can prevent serious repercussions, so people seem to be responsive to tests in this area. In addition, there is nothing to be embarrassed about regarding skin cancers. So, there is little that is intimidating except the seriousness of an area.
Unfortunately, I think publicity does have a great deal to do with it. My suspicion is that most people would not "call about cancer screening tests" voluntarily because they don't want to confront the possibility of having cancer. However, when awareness of a specific type of cancer is raised because of the news surrounding a public figure dealing with some form of the disease - think Katie Couric's efforts regarding colorectal cancer after her husband's death, Lance Armstrong's raising awareness of testicular cancer - people may be prompted to call about screening if they recognize similar symptoms in their health.
Much depends on public awareness of the different kinds of cancer and the levels of threat they pose. Almost all the women I know are very aware of the risks of breast cancer and are checked regularly for signs of this kind of cancer. Most people above the age of 50 also know that colonoscopies should be done every so often.
I don't actually think that more common cancers are the ones that people will have checks for. I think it actually depends a lot more on publicity and the kind of cancers that people know about and are aware of. This is particularly true for breast cancer, for example, as it is a well-publicised disease and much has been done to advertise the checks and smears that you can have to identify any occurrence of the disease in its early stages. However, there are other checks that are not taken up, such as checks for prostate cancer, perhaps because it is potentially more embarrassing and there is less publicity.
I assume you are asking about people calling some kind of a clinic. I would imagine that people will call about some tests more than others because those kinds of cancer are more common. They might also be unwilling to call about some kinds of tests if they are embarrassed about mentioning them -- these are tests like pap smears or mammograms (if that counts as a test) or tests for colon cancer. They'd be more likely to call about things like skin cancer tests, I'd think.
