Cancer is a Water sign, supportive and emotional. Cancer is the mothering, sustaining, nurturing sign of the zodiac. It is the sign of the womb, the house, the home, the interior of all things for it is the protecting or covering principle. Cancer is symbolized by the slow moving crab, identified with its dwelling place. It carries its house upon its back and retreats into it when threatened by exterior forces.
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. Cancer is not a vital sign. It has a sluggishly moving energy flow.
