Do Cancer Screenings Result in Overtreatment?

In recommending that cancer be redefined to reflect new knowledge and that certain conditions no longer be branded as cancer (see our previous post), a National Cancer Institute advisory panel expressed concern that America’s defensive approach to medicine has lead to over-screening for cancer and that cancer screenings are too often resulting in unnecessary treatment.

The panel’s concern was twofold:

  1. Today’s cancer screenings use a level of technology capable of detecting  abnormalities at the cellular level. The problem is that the human body is full of abnormalities; however, not all abnormalities are cancerous nor will most become cancerous.
  2. Americans are so conditioned to think worst-case scenario when cancer is diagnosed that they are unwilling to take a “wait and see” approach. They insist on surgery or other radical treatments such as chemotherapy and  radiation that carry their own significant health risks. In fact, fear of cancer is causing some people to undergo surgery even when no cancer is evident, as was the case earlier this year when actress Angelina Jolie underwent a preventative double mastectomy after discovering that she carries a gene that increases breast cancer risk.

In making its recommendation, the advisory panel stated:

“The word ‘cancer’ often invokes the specter of an inexorably lethal process. However, cancers are heterogeneous and can follow multiple paths, not all of which progress to metastases and death.”

As noted on CNN Health, 10% of localized lung cancer tumors, 20% to 30% of localized breast cancer tumors and 60% of prostate cancer tumors discovered by screening will never harm their victims.

Cancer Experts Recommend Updating Cancer Definitions

There is no more emotionally charged and frightening word than cancer. When spoken in a doctor’s office, patients immediately assume the worst and start counting their days. Most patients consider a cancer diagnosis a death sentence. When cancer screenings detect an abnormality they panic, subjecting their bodies to surgery, chemotherapy and radiation in a desperate bid to live. And even if they survive cancer, most live in constant fear that it will return.

A National Cancer Institute advisory panel sent shock waves coursing through the cancer community this week when scientists recommended that:

  1. The definition of cancer be redefined and updated to reflect modern scientific and medical findings. One of the problems with cancer diagnosis, Dr. Otis Brawley, the American Cancer Society’s chief medical officer, told CNN Health is that oncologists are still using cancer definitions developed in the 1850s. Back then, cancer typically spread through the body before it was diagnosed. Today, cancer screening methods allow oncologists to examine minute samples measured in millimeters. In evaluating such small tissue samples, natural abnormalities can be misdiagnosed as cancer.
  2. The diagnoses of certain illnesses be changed to eliminate cancer references or cancer language. In other words, some diseases currently defined as cancer would no longer be considered cancerous. As explained in a CBS News report, there are certain potentially pre-cancerous conditions that carry only a slight risk of becoming cancerous. Yet because they are defined as “cancer,” “carcinoma” or “neoplasia” patients panic and often undergo unnecessary surgery, chemotherapy or radiation, frequently suffering damaging side effects.
