People who smoke despite having received a diagnosis of cancer are likely to experience higher levels of pain than their non-smoking counterparts.
This is according to recent research published in the journal Pain and conducted by scientists from Texas A&M University.
The team revealed that smoking resulted in "increased pain severity" among cancer patients to such an extent that it interfered with the individual's daily routine.
Current smokers were confirmed to experience more severe pain than those who had never smoked, while an inverse relation between pain and the number of years since quitting was identified among former smokers.
Lori Bastian from Duke University, who wrote a commentary on the report, remarked: "The major strength of this study is the diverse types of cancer and stage of disease.
"Although more research is needed to understand the mechanisms that relate nicotine to pain, physicians should aggressively promote smoking cessation among cancer patients.
Preliminary findings suggest that smoking cessation will improve the overall treatment response and quality of life."
