  • A recent study published in Nature Reviews Clinical Oncology says cancer cases (including of the breast, colon, esophagus, and more) have increased since 1990.

  • Researchers believe this increase in cancer risk is linked to changes in diet, lifestyle, weight, environmental exposure and gut health.

The incidence of some cancers is declining in older people, especially colorectal cancer. But there is a troubling trend for those under the age of 50: a higher cancer prevalence. And it’s possible that the younger you are, the greater your risk.

A recent study published in Nature Reviews Clinical Oncology notes that a dramatic increase in cancers of the breast, colon, esophagus, kidneys, liver and pancreas began around 1990 and has been a concern ever since.

Analyzing data on cancer diagnoses and patient ages, researchers found that each decade carries a higher risk of developing cancer later in life. For example, those born in 1960 had a higher incidence of cancer by age 50 than those born in 1950 when they turned 50. And those born in 1970 had a higher risk than those in a 1960 birth cohort.

In reviewing the data, researchers hypothesized that the rise in early-onset cancers may be related to shifts in what’s called the exposome, which consists of diet, lifestyle habits, weight, environmental exposure and gut health. All of these have undergone substantial changes in recent decades, and each has been independently linked to cancer outcomes, according to study co-author Shuji Ogino, MD, Ph.D., a researcher in the division of pathology at Brigham and Women’s Hospital in Boston.

“On both an individual and societal level, there are many recommendations we can take from this in terms of cancer prevention for younger people,” he said. Bicycles. These include pursuing regular exercise, avoiding sugar and highly processed foods, cutting back on alcohol, maintaining good oral hygiene, adopting beneficial sleep habits, getting appropriate vaccinations — especially for cancer-causing microorganisms like HPV — and no smoking. People should start all these habits as early as possible,” says Ogino.

Starting these habits early doesn’t mean you’re in your thirties, Ogino added. It’s more like your toddler days. “The early cancer epidemic is due to the food, environment and lifestyle we were given as children,” he said. “The cancer risk of our children and future generations depends on us. We think it is possible to reverse this trend, but we need a lot of effort.”

While we don’t have a time machine to adjust your childhood habits, it’s not too late to lower your risk. And a good starting point is regular exercise, lead author Tomotaka Ugai, MD, Ph.D., also in the pathology department at Brigham and Women’s Hospital, told me. Bicycles.

“We believe that physical inactivity has a major impact on the emergence of early-onset cancers, and previous studies clearly show that sedentary behavior is associated with increased risk,” he said, adding that the risk could be higher. with other risks piled upon it. peak of inactivity, such as poor sleep, pollution effects and regular consumption of highly processed foods.

Adopting healthy habits — and especially encouraging kids and teens to do the same — could go a long way toward changing the early cancer trend.
