Cancer is a Water sign, supportive and emotional.
Cancer is the sign of emotional sensitivity and sympathy.
This sign, more than any other, is associated with domestic security and homemaking. Cancers are known for being very complex and often difficult to understand due to their ever changing mood swings. One minute they can be cranky and combative and the next they may seem the sweetest and most caring individuals. Cancers have a highly developed instinct for self-defense that protects them from their inner vulnerability and shyness. Like a Crab's shell, their personalities often project a tough exterior within which they can retreat to.
