Cancer is the 4th sign of the zodiac, and its ruling planet is the Moon.

Just as the Moon moves through its cycles and causes the tides to ebb and flow, the emotional state of those born in Cancer is fluid and constantly changing.  Emotion and intuition rule, and the Cancer sign often goes through constant change in their physical world as well as emotional. If variety is the spice of life, you’ll get plenty of spice if you keep company with a Cancer and maybe learn to howl at the moon yourself a bit. But when it comes to nurturing and caring, all that emotion is put to good use. They are experts at smoothing over wounded emotions, which makes them ideal in health related fields and management.
