Cancer rules the Fourth House of the Zodiac, known as the “House of Family and Home.” This house represents the effects of our earliest experiences and of the nurturing we receive as children, and the way this anchors and guides our lives. Anyone lucky enough to be within a Cancerian’s inner circle enjoys a secure sense of comfort and belonging. Cancer is a water sign associated with the moon, a combination that leads to shifting moods and deeply felt emotions. Though they may sometimes appear impervious on the outside, perhaps even irritable, inside they’re all heart, kind and loving to the core.
