The proportion of people needing lung cancer treatment is likely to fall by nearly a fifth over the next 20 years, scientists have claimed.
Experts at Cancer Research UK believe that anti-smoking measures have played an important role in reducing the rate of lung cancer.
Smoking causes around nine in ten cases of lung cancer, so as smoking rates continue to fall, so should rates of the disease.
However, the overall number of people diagnosed with lung cancer is likely to continue to rise as people are living for longer and the disease can take years to develop.
Report co-author Professor Max Parkin said: "These predictions are based on what we know to date about the current figures and trends for lung cancer. We can see that lung cancer rates should continue to drop but the number of cases will increase."
The expert noted that the increase will mostly affect women, reflecting the high rates of female smokers in the 1970s.
At present, around 38,500 people are diagnosed with lung cancer every year in the UK, making the disease the second most common cancer.
