Adenomas are benign tumors of gland-forming cells, and are usually specified further by their cell or organ of origin, as in hepatic adenoma (a benign tumor of hepatocytes, or liver cells).
Additionally, there were approximately 10 million mortalities due to cancer in 2020 [3] and, there is an overall trend which demonstrated that malignant mortality has increased by 28% over the past 15 years. [26] Lung cancer has the highest mortality rate in comparison to other forms of cancer, with the leading cause of development due to ...
