ERBB2 and lung cancer: A recent study shows that there is a significant disparity across all survival outcome indices in women of African ancestry with ERBB2+ breast cancer in comparison to women of other ancestry with ERBB2+ breast cancer (Zhao et al, 2020).The prevalence of breast and lung cancer and their related mortality arises from the oncogenes that drive the malignant breast and lung tissues to excessively proliferate and then metastasize to lymph nodes and onward to organs such as lungs, liver, and brain leading to the death of the patient.
