The human body is made up of over 37 trillion cells. The normal cells have similar shapes, while cancer cells have irregular and different shapes. Cancer cells keep growing, the overgrowth of cancer cells leads to tumor while, normal cells stop growing when enough cells are present.
Normal cells receive and respond to the signal to stop growing while cancer cells ignore signals and keep growing. Normal cells stay in their intended location, while cancer cells spread to different locations.
Normal cells repair themselves or die if they are not healthy, while cancer cells do not repair themselves when they are old and damaged.
Normal cells have large cytoplasmic volumes, while cancer cells have small cytoplasmic volumes. Normal cells mature into specialized cells, while cancer cells can remain immature and undifferentiated.
