The Sharon Clough Foundation is a 501(c)3 non-profit foundation fighting lung cancer. The purpose has several goals. First, to fight lung cancer and raise awareness for an invisible disease. Lung cancer kills more people than breast cancer, prostate cancer, and colon cancer combined. Second, to raise money to help find a cure for lung cancer. In 2007, the National Cancer Institute budgeted only 5%, $242.9 million, of it's total $4.8 billion budget for lung cancer research. But, out of the $242.9 million only 38%, $92.3 million, was spent on early detection, diagnosis, treatment and prognosis of lung cancer. The Center for Disease Control and Prevention and the Department of Defense earmarked no money for lung cancer research in 2007. According to the NIH, the government funding for lung cancer research continues to drop, despite increases to the National Cancer Institute. Third, to find an early test that detects lung cancer in its early stages when lung cancer is most likely to be treated and cured. There is currently no approved screening for early detection of lung cancer, although spiral CT scans are much better than regular chest x-rays.
