Lung Cancer - A cancer that starts in the lungs. There are two main types of lung cancer: Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. Small cell lung cancer makes up about 20% of all lung cancer cases. If the lung cancer is made up of both types, it is called mixed small cell/large cell cancer. If the cancer started somewhere else in the body and spread to the lungs, it is called metastatic cancer to the lung.
As the War on Cancer enters its fifth decade and the number of people being diagnosed with cancer continues to rise, Lung Cancer Alliance (LCA) called for more aggressive integration of advanced imaging technology and biomedical research to improve prevention, earlier detection and treatment of cancer.
"We have developed remarkable new tools for imaging and biomarker identification that can bring about enormous changes at this moment in time and drive rapid improvements in the entire continuum of care in cancer," said Laurie Fenton-Ambrose, President and CEO of Lung Cancer Alliance.
"But imaging and biomedical research must be linked together," she said.
In 1975, when Congress passed the National Cancer Act, dubbed the War on Cancer legislation, 400 new cases of cancer were being diagnosed each year for every 100,000 people in the population. According to the latest figures, in 2008 that number rose to 463 new cases for every 100,000 people.
Over 1.6 million people will be diagnosed with cancer this year.
While the rate and number of people being diagnosed with cancer overall continues to climb, some progress has been made in reducing the percentage of people who die from cancer, primarily because of screening and better treatments. However the decline is uneven.
The drop in lung cancer death rates among men reflects the drop in the number of men smoking and being diagnosed with lung cancer, but not a reduction in the lethality of lung cancer, which continues to kill three times as many men as prostate cancer.
For women, incidence or mortality rates are still twice as high as they were in 1975 and nearly twice as many women will die of lung cancer than breast cancer.
In addition the percentage of women with lung cancer who have never smoked is twice as high as men.
"The overall numbers are staggering," said Fenton-Ambrose.
Of the 577,000 people who will die of some form of cancer this year, one in four women and three in ten men will die of lung cancer - more than the combined total of deaths from breast, prostate, colon and pancreatic cancers.
"However, this past year has also brought us the most significant advance we have ever seen for lung cancer - the validation of CT screening as a life-saving tool that can dramatically reduce lung cancer mortality among those at high risk," she said.
According to several national and international studies, that reduction would be at least 20% and possibly as high as 50-60%, which translates to 35,000 to 95,000 lives saved a year.
Screening can also stimulate research into precancerous conditions, genetic mutations and biomarkers that will improve risk assessment, diagnosis and treatment for all types of lung cancer, including lung cancers not associated with smoking.
Lung Cancer Alliance is dedicated to providing support and advocacy for those living with or at risk for lung cancer. LCA is committed to reversing decades of stigma and neglect by empowering those with or at risk for lung cancer, elevating awareness and changing health policy at both the federal and state level.
