Answer 1

Oncology:

1. Oncology is a scientific field that focuses on the investigation of tumorous cell development and its management.
2. Galen, a scientist, coined the term "oncos" to characterize the tumor.

Cancer cells:

1. Cell growth and differentiation are often the tightly regulated processes that occur in our bodies.
2. However, these two regulatory processes fail in cancer cells, which are cells that cause tumors.
3. The process of contact inhibition, which holds all of the cells together and prevents their uncontrolled growth, is present in normal cells.
4. However, malignant cells lose this ability, causing the uncontrolled expansion of the cell that results in tumors.

Final answer: Oncology is the study of cancer cells.
