Lung cancer is a leading cause of death in the United States. According to a study published in The Journal of Nuclear Medicine, positron emission tomography and computed tomography can be used as useful tools to predict lung cancer at an early stage. The lung cancer patients who were at the center of this study were being treated by radiofrequency ablation (RFA). RFA uses thermal energy to kill cancer cells and is useful for those patients who cannot undergo surgery or other therapies.
This was a five year old study which followed 68 cancer patients. Several indicators of local recurrence were predicted by reviewing PET/CT scans performed before and after RFA. The factors determining potential local reference in pre RFA scans were lesion size and type of tumor. However, after RFA, the factors that could predict the likelihood of recurrence were size of ablation margins, standardized uptake value and so on. The outcome of the above study was that pre and post PET/CT scans can help tremendously in the early diagnosis of lung cancer.
Other important recent study on cancer has claimed that a small dose of Aspirin everyday can lower the risk of different types of cancers. This research was conducted at Oxford University and found that the cancer deaths were reduced by one-fifths after taking aspirin. The study covered over 25,000 people, mostly from the UK. Aspirin is already known to be good for heart and now its positive effect on cancer patients or those who might have cancer is incredible. Experts believe that the potential benefits of Aspirin are far more than its after-effects.
