Which of the following statements correctly describes a characteristic of cancer cells, as discussed in the "Loss of Cell Cycle Controls in Cancer Cells" section?

• A: Cancer cells always require a higher concentration of external growth factors than normal cells to divide in culture.
• B: Cancer cells typically stop dividing at specific checkpoints in the cell cycle, similar to normal cells.
• C: Cancer cells are considered "immortal" because they can go on dividing indefinitely in culture if provided with a continual supply of nutrients.
• D: The primary reason cancer cells exhibit abnormal division is always due to their ability to produce their own required growth factors.
