One of these things is not like the others

Didn't Sesame Street have a song like that?

One of these things is not like the others,
One of these things just doesn't belong,
Can you tell which thing is not like the others
By the time I finish my song?

The CDC calls the following 5 items, "high-value prevention services" which can save 100,000 lives each year.

1. Smoking cessation assistance
   
2. colorectal cancer screening
   
3. breast cancer screening
   
4. annual influenza immunization
   
5. daily aspirin to prevent heart disease.

Three quarters of former smokers quit on their own. And I don't know anyone who successfully, permanently stopped smoking with a government sponsored workshop, phone call counseling, nasal spray or a drug patch. Do you? The studies only have a few months or a year follow-up, but somehow the drug companies have got that one included in many government programs.

But I have heard of other uses for the nicotine patch I might consider--like improving memory in older persons. Now that I could get into.

Only the aspirin and the immunization are actually preventative. Two of these are screening for what you already have or will have. Breast cancer screening can find a lump--but doesn't prevent it. Colonoscopies can spot trouble spots that will become cancer but aren't there yet.
