A leading oncologist is raising the alarm about the staggering surge in cancer cases among young people.

North Carolina‘s Duke University oncologist Dr. Nicholas DeVito is warning that “every new patient” who now comes to his clinic is under 45 years old.

Dr. DeVito says he and his colleagues have experienced a complete demographic switch in recent years.

Based on what he’s seeing every day, talking to patients on the ground and analyzing the data, DeVito is now issuing a red alert to warn the public about the phenomenon.

However, the doctor is raising concerns that U.S. government officials are refusing to address or even acknowledge the dramatic surge in cancer cases.

The physician wrote for STAT News:

“The desire to protect Americans from substances that cause cancer and other diseases should transcend party affiliation and political motivation to overcome industrial lobbying efforts.”

In recent years, multiple studies and oncology experts have warned that cancer cases have been skyrocketing in younger people.
