Lung and bronchus cancer are among the common types of cancer affecting the United States population. However, the rate of incidence of this disease has declined markedly in the U.S. from 2000 to 2015. Overall, according to the National Cancer Institute (2018), there are differences between the rates of occurrence of lung and bronchus cancer among races in the U.S. However, the burden of the disease is more significant among Blacks with a mean of 70.07, as compared to individuals from other races. Nonetheless, it is less prevalent among Hispanics. The second group constituted Whites, which was followed by American Indians and Asians or Pacific Islanders. Moreover, unlike other races, the difference between the mean and the median was highest in Whites; therefore, suggesting that the distribution is skewed to the left. The distribution of other races appears to be normal and symmetrical. Lastly, Blacks, American Indians, and Whites had higher standard deviations, which suggests that there are more underlying or predisposing factors to lung and bronchus cancer in those groups. However, this is the opposite for Hispanics and Asians or Pacific Islanders.
Lung and bronchus cancer affects all population groups in the US. However, specific races appear to have a more disproportionate burden of the disease as compared to others. Although lung and bronchus cancer incidence is noted to decrease overall among all ethnic groups in the US from 2000 to 2015, certain groups continue to be at risk. For instance, based on the National Cancer Institute data on lung and bronchus cancer, Blacks are noted to have higher prevalence rates than all other groups (National Cancer Institute, 2018). Whites followed this and were preceded by American Indians and Asians or Pacific Islanders. Hispanics have the least reported incidence rates. Moreover, when it comes to Asians/ Pacific Islanders, over the 15 years, the most commonly reported cases were 36.6 annually. On the other hand, for Hispanics and Whites, it was 34.1 and 65.8 cases, respectively. Nonetheless, Blacks and American Indians showed no reoccurring number of cases. Furthermore, Blacks have a higher standard deviation, therefore, suggesting that most cases are inconsistent as they do not closely revolve around the mean. Whereas, this is the reverse for Hispanics and Asian or Pacific Islanders.
