Detailed explanation-1: -The nucleus from a cancer cell is larger and darker because it often contains too much DNA.

Detailed explanation-2: -In addition, cancer cells often have an abnormal shape-both the cell and the nucleus (the “brain” of the cell.) The nucleus appears both larger and darker than normal cells. The reason for the darkness is that the nucleus of cancer cells contains excess DNA.

Detailed explanation-3: -Under a microscope, cancer cells may look very different from normal cells. Cancer cells: are different sizes and some may be larger than normal while others are smaller. often have an abnormal shape.

Detailed explanation-4: -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.

Detailed explanation-5: -[208] reported that in many cancer cells, the nuclear envelope transiently ruptures and then reseals during interphase, resulting in temporary exchange between the nucleus and cytoplasm and the occasional entrapment of cytoplasmic organelles inside the nucleus.
