A report from the International Agency for Research on Cancer (IARC), which gathers and reviews the latest scientific findings, was shared on September 25 during the World Cancer Congress in Hong Kong. The report highlights that quitting tobacco use after a cancer diagnosis can significantly improve survival rates and lower the risk of the disease worsening. This finding underscores the importance of smoking cessation as a critical factor in cancer treatment and recovery. According to the study, individuals diagnosed with lung cancer who quit smoking can reduce their risk of death and cancer progression by up to 55%. This benefit is not limited to lung cancer patients. The research also suggests that quitting tobacco can be helpful even for those with advanced-stage cancer and for cancers in other parts of the body. The study emphasizes that smoking cessation should be a priority for cancer patients, regardless of the cancer type or stage. Quitting tobacco can have a positive impact on overall health, potentially improving the effectiveness of other cancer treatments and reducing the likelihood of complications. Health professionals and researchers are encouraging cancer patients to consider quitting tobacco as part of their treatment plan. The findings from the IARC report add to the growing body of evidence supporting the benefits of smoking cessation in improving outcomes for cancer patients.
