Macmillan's general manager in Scotland Allan Cowie said: "In the past lung cancer has to an extent been seen as an illness that affects men, however this new research shows that it is vital that both sexes know the symptoms of lung cancer and get themselves checked out if they have any concerns.
"We know one of the reasons more women will be living with lung cancer in the future is that our population is ageing and an older population increases the risk of cancer. However this also poses challenges in detecting cancer early as we know older people tend to wait longer to visit the doctor when they are ill.
"This research shows it is vitally important that the Scottish Government's Detect Cancer Early Campaign makes it a priority to raise awareness of lung cancer among women, while also encouraging older women in particular to get themselves checked out as early as possible if they have any symptoms."
Motherwell grandmother Carole McCluskey, 66, was diagnosed with lung cancer in August 2010.
She said: "It is absolutely shocking that so many women are going to be living with lung cancer in the future. Most women know the signs of breast cancer but probably not many know the signs of lung cancer but it's really important that changes."
