Smoking is not merely a leading cause of lung cancer; it is directly linked to more than 10 different types of cancer, according to Professor Ozcan Yildiz, a specialist in Medical Oncology at Biruni University Faculty of Medicine Hospital, who told Anadolu Agency.

In a statement from the hospital, Yildiz underscored that smoking significantly elevates cancer risk and should not be viewed solely as a trigger for lung cancer.

“Scientific evidence demonstrates that tobacco use contributes to the development of at least ten distinct types of cancer,” he noted.

Beyond the lungs: Widespread cancer risks

According to Yildiz, smoking is associated with cancers of the:

  • Mouth
  • Throat and pharynx
  • Esophagus
  • Stomach
  • Pancreas
  • Liver
  • Kidney
  • Bladder
  • Cervix

He further highlighted its influence on colorectal cancer and certain hematologic malignancies.

“Tobacco smoke contains numerous chemical compounds, many of which are carcinogenic,” he explained. “Consequently, both smokers and individuals exposed to secondhand smoke are at significant risk.”

Secondhand smoke: A hidden threat

The expert also drew attention to the dangers of passive smoking, particularly for children and individuals with chronic health conditions, for whom secondhand smoke poses a serious health hazard.

Yildiz emphasized that quitting smoking at any age yields substantial health benefits. The body begins a natural repair process once tobacco use ceases, gradually reducing cancer risk over time.

He recommended that individuals adopt healthy lifestyle practices, including balanced nutrition, regular physical activity, and participation in routine cancer screening programs.

“Early cessation of smoking, combined with a healthy lifestyle and regular medical check-ups, remains one of the most effective strategies to reduce cancer risk,” he stated.
