'Cancer patients exposed to air pollution at higher risk of heart disease'

Air pollution could increase the risk of heart diseases and death in cancer patients, adding to health inequities experienced by the group, according to a new research.

The research reviewed eight papers published between 2000 and 2023 that studied the direct impacts of air pollution on cardiovascular disease, such as heart attack and stroke, and cancer. More than 1.1 crore participants were included in the review.

The researchers found that exposure to fine particulate (PM2.5) pollution weakened the body's detoxification and its defences against inflammation, which are risk factors common to both cancer and cardiovascular disease.

"Air pollution plays an undeniable role in the field of cardio-oncology," the authors, including those from Huazhong University of Science and Technology, China, wrote.

Even short-term exposure to unhealthy levels of air pollution can quickly affect the heart health of cancer patients, according to the researchers. The findings are published in the Journ
