Dividing breast cancer cell

Coloured scanning electron micrograph (SEM) of a breast cancer cell dividing, showing its uneven surface & cytoplasmic projections. It is in the telophase stage of cell division (mitosis). In this last stage of mitosis, the chromosomes have already been duplicated and distributed to each daughter cell. However, the two daughter cells are still connected by a narrow cytoplasmic bridge. Cancerous (malignant) breast cells form tumours, which possess the ability to invade surrounding tissues. Malignant cells divide rapidly and grow in a chaotic manner. Breast cancer is the most common type of cancer in women.
