It was never definite on who needs to be evaluated for cancer, when it should be done and what kind of test should be applied .
Not long ago, guidelines on examining for breast , colo-rectal, prostate and ovarian cancer needed revisions . Its constant change rests on who will write the guideline. Today a guideline is combined by an organization for people who are generally at risk of the 5 common cancers.
The American College of Physicians evaluated cancer test suggestions from major physician and cancer organizations yet they are mainly focussing on clearing up misleading guidelines. They showed the importance of a test for better health as to evade harm and stop waste.
“Overly intense screening can sometimes lead to over-diagnosis and lead to overtreatment,” stated Dr. Wayne Riley, president of the American College of Physicians.
High value examination offer benefits rather than harm and cost .
“An excellent example of a high value care screening would be one for colon cancer in those between the age of fifty and seventy-five,” said Riley.
On the other hand , low value examination offers few benefit for the threat or cost.
“Lower value would be screening women for cervical cancer who no longer have a cervix,” said Riley. “Studies have consistently shown that approximately one third of the health dollars that we spend in the country are likely spent on treatments or screening that have very little impact”
It is feared that people may overestimate the benefits and underestimate the limitations of screening , such as in a report that notably said there is no examination obtainable for ovarian cancer in average risk women.
The guidelines emphasize that patients and doctors must consider the hidden threats of examinations and not just the possible benefits.
