1. Unnecessary colonoscopies
Although this test is beneficial before age 70, its use after that age can lead to more complications than benefits. One in three older adults who meet unnecessary colonoscopies ends up with surgery that could have been avoided.
Furthermore, the risk of bleeding, infections and intestinal perforations increases greatly with age.
2. Late mammograms
After age 70, mammograms can cause false positives and unnecessary treatments, such as surgery, chemotherapy, or radiation therapy. Breast can.cer at this stage often proceeds slowly and doesn’t always pose an immediate risk.
Anxiety and the side effects of aggressive treatments can be more damaging than the disease itself.
3. MRIs or memory scans (such as brain PET scans)
These studies can increase unwarranted alarms about possible dementia or cognitive impairment. Often, “abnormalities” are exposed that don’t affect daily life, but which lead to experimental treatments or unnecessary medications with adverse effects.
Overdiagnosis of Alzheimer’s, for example, can have a strong psychological impact.
4. Prostate cancer screening tests (PSA )
The prostate-specific antigen (PSA) test may seem like a preventative measure, but after age 70, it often produces confusion. Many men are diagnosed with slow-growing can.cers that wouldn’t require intervention. However, they end up undergoing biopsies, surgeries, or radiation, with consequences such as incontinence or erectile dysfunction.
5. Unnecessary chest x-rays or CT scans
These types of tests are constantly ordered to eliminate lung problems. However, in older adults, they can detect benign nodules that trigger a series of studies, biopsies, and even high-risk surgeries.
Furthermore, repeated exposure to radiation increases the risk of developing certain types of cancer by up to 5%.
Final reflection:
Many checkups that were helpful before age 70 can become hazardous as we age. It’s important that older adults meet their doctors about the real risks of these tests and consider whether they will truly enhance their quality of life.
