Lung cancer is the second most common cancer in both men and women globally. More than one million lung cancer cases are diagnosed worldwide each year. The leading cause of cancer death is lung cancer in the United States and worldwide [1]. According to the American Cancer Society, there were an estimated 222,500 new cases of lung cancer and 155,870 deaths from lung cancer in the United States in 2017. Early detection and diagnosis, as well as accurate localization in lung intervention, are the keys to reducing the death rate from lung cancer [1].

Breast cancer is the most frequently diagnosed cancer in the United States and ranks second as the most common cause of cancer-related death among women (Siegel et al., 2020). According to American Cancer Society (ACS) estimates, approximately 276,480 new cases of breast cancer would have been diagnosed in 2020, and greater than 42,000 deaths would be attributed to breast cancer (ACS, 2020). Although only 7% of all cancer-related deaths are from breast cancer every year, it is the leading cause of death among women between the ages of 40 and 49 years (Siegel et al., 2020). The death rate associated with breast cancer, however, has decreased by 1.3% annually from 2013 to 2017.

The American Cancer Society estimates that approximately 217,440 new cases of breast cancer will have been diagnosed in the United States in the year 2004 and approximately 40,580 patients will die of this disease. Breast cancer is the most common malignancy in women in the United States and is second only to lung cancer as a cause of cancer death. The incidence of breast cancer has increased steadily in the United States over the past few decades, but breast cancer mortality appears to be declining. This suggests a benefit from early detection and more effective treatment. For the most recent version of the guidelines, please visit NCCN.org

. . . there is no increase in the death rate ("mortality incidence") from cancer during the last 44 years; this despite constantly improving medical diagnosis and reporting procedures. The rate has hovered at about 131 cancer deaths per hundred thousand persons per year. If deaths from lung cancer are subtracted (and the conservative assumption is made by experts that 85 percent or more of them are due to cigarette smoking), the overall "incidence" of death from cancer would be less today than in 1933, by about 10 percent. So there is no epidemic of cancer in the United States, but there is a disproportionate number of cancer deaths due to cigarette smoking. Given our current economic problems, provision of more tax money to the National Cancer Institute for more "research" should lie low on the list of our national priorities. Tax money should instead be substantially diverted from the "cancer establishment" and be channeled into a nationwide action program about the dangers of cigarettes, a program which ought to start in kindergarten. Cigarettes cause not only lung cancer but a host of other, more numerous and debilitating diseases; many clinicians estimate that 25 percent or more of hospitalization, doctor and prescription drug bills are generated directly or indirectly by cigarette smoking. If we could save one-half of the $150 billion currently being spent each year on these items, the nation would enjoy a windfall profit. I see no governmental leaders taking any bold, effective action to expurgate what is so obviously and offensively scandalous.

Cancer of the lung is a group of heterogeneous malignant disorders composed of small cell lung cancer (13%), non-small cell lung cancer (NSCLC) (86%), and rare thoracic malignancies such as mesothelioma and carcinoid tumors. In 2008 the American Cancer Society estimated that 215,020 people in the United States would develop lung cancer, and 161,840 people would die of their disease. In men the age-adjusted cancer death rate for lung cancer peaked in 1990 at approximately 90 deaths per 100,000 and has since decreased to 70 per 100,000. In women, the incidence reached a plateau in 1990 at 40 per 100,000. These changes are in part due to alterations in smoking patterns, but the overall incidence of lung cancer continues to increase with the aging population. Despite the trend of decreased smoking rates in industrialized countries, lung cancer remains the leading cause of cancer death in both men and women in the United States (American Cancer Society, 2008). Lung cancer is also the leading cause of cancer death worldwide.

Lung cancer is the leading cause of cancer-related death. According to the American Cancer Society, there were an estimated 222,500 new cases of lung cancer and 155,870 deaths from lung cancer in the United States in 2017. Accurate localization in lung interventions is one of the keys to reducing the death rate from lung cancer. In this study, a total of 217 publications from 2006 to 2017 about designs of medical devices for localization in lung interventions were screened, shortlisted, and categorized by localization principle and reviewed for functionality. Each study was analyzed for engineering characteristics and clinical significance. Research regarding interventional imaging equipment, navigation systems, and surgical devices was reviewed, and both research prototypes and commercial products were discussed. Finally, the future directions and existing challenges were summarized, including real-time intra-procedure guidance, accuracy of localization, clinical application, clinical adoptability, and clinical regulatory issues.

Objectives: Evaluate the relationship between the opioid epidemic and homicide rates in the United States. Methods: A county-level cross-sectional analysis covering the period 1999 to 2015. The race-specific homicide rate and the race-specific opioid-related overdose death rate are regressed on demographic, social, and economic covariates. Results: The race-specific opioid-related overdose death rate is positively associated with race-specific homicide rates, net of controls. The results are generally robust across alternative samples and model specifications. Conclusions: We interpret the results as reflecting the violent dynamics of street drug markets, although more research is needed to draw definitive conclusions about the mechanisms linking opioid demand and homicide.
