Scientists investigated whether infection with virus Y could lead to liver cancer. They grew two samples of liver cells for 4 days under identical conditions.
| Liver cells | Number of cells at the start | Number of cells after 4 days |
|---|---|---|
| Not infected with virus Y | 5000 | 6200 |
| Infected with virus Y | 5000 | 24 800 |
Explain how these results suggest that infection with virus Y could lead to liver cancer.
