Lung cancer is when abnormal cells divide in an uncontrolled way to form a tumour in the lung. Survival outcomes depend largely on how far the cancer has spread so being aware of the warning signs is imperative. Unfortunately, as the NHS points out, there are usually no signs or symptoms in the early stages of lung cancer, but many people with the condition eventually develop symptoms.
Certain lifestyle factors have also been shown to reduce a person’s risk of developing lung cancer.
A study published in JAMA Oncology found that a diet high in fibre and yogurt was associated with a reduced risk for lung cancer.
The findings, which are the result of an analysis of data from studies involving 1.4 million adults in the United States, Europe and Asia, found that the highest yogurt and fibre consumption had a 33 percent reduced lung cancer risk as compared to the group who did not consume yogurt and consumed the least amount of fibre.
“This inverse association was robust, consistently seen across current, past and never smokers, as well as men, women and individuals with different backgrounds,” said senior author Xiao-Ou Shu, MD, PhD, MPH, Ingram Professor of Cancer Research, associate director for Global Health and co-leader of the Cancer Epidemiology Research Program at Vanderbilt-Ingram Cancer Center.
This means the outlook for the condition is not as good as many other types of cancer.
According to the NHS, about one in three people with the condition live for at least one year after they’re diagnosed and about one in 20 people live at least 10 years.
However, survival rates vary widely, depending on how far the cancer has spread at the time of diagnosis. Early diagnosis can make a big difference.
