World Lung Cancer Day is observed on 1 August annually, to support the educational drive to raise awareness about lung cancer, its impact, and the steps people can take to minimise their risk. This year’s global theme, Stronger Together: United for Lung Cancer Awareness points to the power of unity in the fight against lung cancer through early screening.
Lung cancer remains one of the most common and often fatal cancers worldwide, with approximately 2.2 million new cases across the globe and 1.8 million deaths reported in 2020, according to the Global Cancer Observatory.
Dr Rouchelle Marais, a clinical radiation oncologist at the Life Oncology unit at Life Eugene Marais Hospital, emphasises the importance of preventive measures in reducing the incidence of lung cancer. “Smoking is the leading cause of lung cancer, but the good news is that quitting smoking at any age can significantly reduce the risk,” says Dr Marais. “Avoiding exposure to second-hand smoke, maintaining a healthy diet rich in fruits and vegetables, and engaging in regular physical activity are crucial steps everyone can take.”
In addition to lifestyle changes, Dr Marais highlights the importance of minimising exposure to known carcinogens such as radon, asbestos, and air pollution. “Following safety protocols in workplaces and ensuring good indoor air quality can further reduce the risk of lung cancer,” Dr Marais advises. All employers in South Africa have a legal obligation to provide and maintain a working environment free of risk to the health and safety of employees. Occupational health services, which at Life Healthcare group is offered through Life Health Solutions, offers comprehensive occupational health and safety services to make compliance easy. For individuals at high risk, such as heavy smokers or those with a family history of lung cancer, regular medical check-ups and screenings are essential.
Advances in healthcare have resulted in more treatment modalities in place to treat lung cancer such as stereotactic radiosurgery which can be used in higher doses. Fewer treatments are necessary to ablate the tumour if the cancer is detected in its early stages, says Cobie Crawford, radiotherapist at Life Eugene Marais Hospital.
Early detection through screenings can lead to more effective treatment and better survival rates. World Lung Cancer Day serves as a reminder of the collective efforts needed to support people on their treatment journey for this condition. “By raising awareness and promoting preventive measures, we improve the quality of life for many and work towards better health outcomes,” says Crawford.
