Your question: How do pathologists distinguish between normal and cancer cells?

How can you distinguish between cancer cells and normal cells?

Normal cells follow a typical cycle: They grow, divide and die. Cancer cells, on the other hand, don’t follow this cycle. Instead of dying, they multiply and continue to reproduce other abnormal cells. These cells can invade body parts, such as the breast, liver, lungs and pancreas.

How can you identify the cancer cells?

In most situations, a biopsy is the only way to definitively diagnose cancer. In the laboratory, doctors look at cell samples under the microscope. Normal cells look uniform, with similar sizes and orderly organization. Cancer cells look less orderly, with varying sizes and without apparent organization.
