Radiation exposure linked to pulmonary hypertension after lung cancer treatment

AI Summary

A study links radiation exposure during lung cancer treatment with a higher risk of pulmonary hypertension. The increased pressure in arteries carrying blood from the heart to the lungs can eventually lead to right-sided heart failure.

Lung cancer patients undergoing radiation treatment may be at higher risk of developing pulmonary hypertension, a type of high blood pressure that affects the arteries that carry blood from the right side of the heart to the lungs. Over time, that heightened pressure can lead to right-sided heart failure.
