Question

What is cancer?

Answer 1

Cancer:

1. An unregulated division of aberrant cells in an area of the body causes cancer.
2. Cancer is one of humanity's most feared diseases, and it is a leading cause of death worldwide.
3. Normal cells have a feature called contact inhibition, which prevents them from growing out of control when they come into contact with other cells.
4. This property appears to have been lost in cancer cells.
5. As a result, malignant cells continue to divide, resulting in tumor-like aggregates of cells.
6. Carcinogens ( chemical, biological, or physiological factors) can cause normal cells to transform into malignant neoplastic cells.
