A new analysis of a national cancer database finds a bump in cancer diagnoses at age 65.<\/p>\n
The finding suggests many people wait until they are eligible for Medicare before they seek care.<\/p>\n
A couple of years ago, Joseph Shrager, professor of cardiothoracic surgery at Stanford School of Medicine, noticed a statistical anomaly in his practice. It seemed that patients were diagnosed with lung cancer at a surprisingly higher rate at 65 years old than, say, at 64 or 66.<\/p>\n
“There was no reason rates should differ much between the ages of 63 and 65,” Shrager says. He talked it over with his thoracic surgeon colleagues at Stanford who said they were seeing something similar. They wondered if the jump in diagnoses<\/a> might be a result of patients delaying care until they became Medicare eligible at 65.<\/p>\n “If this were true, and patients were delaying screenings or treatments for cancer, it could impact their survival,” Shrager says. A quick exploratory analysis of their own practices showed a twofold increase in lung cancer surgeries in 65-year-old patients compared with 64-year-olds.<\/p>\n “We decided to explore this, and its broader implications, in a larger population,” Shrager says.<\/p>\n In a follow-up study published in Cancer<\/a><\/em>, the researchers found a substantial rise nationwide in new cancer diagnoses at 65\u2014not only for lung cancer but also for breast, colon, and prostate cancer. The four are the most common cancers in the United States.<\/p>\n “Essentially we showed there is a big jump in cancer diagnoses as people turn 65 and are thus Medicare-eligible,” says Shrager, the study’s senior author. “This suggests that many people are delaying their care for financial reasons until they get health insurance through Medicare.”<\/p>\n Researchers analyzed data from hundreds of thousands of patients 61-69 years old and diagnosed with lung, breast, colon, or prostate cancer from 2004 to 2016. The patients, identified from a national database, included 134,991 with lung cancer, 175,558 with breast cancer, 62,721 with colon cancer, and 238,823 with prostate cancer.<\/p>\n There was a greater jump in lung, breast, colon, and prostate cancer diagnoses at the transition from 64 to 65 than at all other age transitions, the research shows. Lung cancer rates showed a consistent increase of 3-4% each year for people aged 61 to 64, then at 65 that percentage doubled.<\/p>\n The increase was even more pronounced in people with colon cancer, which showed an annual growth rate of just 1-2% in the years leading up to Medicare eligibility, then jumped to nearly 15% at 65. In the years following age 65, diagnosis rates declined for all cancers, the study shows.<\/p>\nJump in 4 common cancer diagnoses<\/h3>\n
