Modern
Cancer is a cardinal water sign ruled by the Moon, the archetype of the nurturer, protective and feeling, tending home and belonging. Wherever Cancer falls in a chart, that area of life takes on this character: the water temperament (its way of meeting the world) in its cardinal mode (how it moves and changes). The gift is the sign's strength at its best; the work is balancing it against its opposite. At your best you live the sign's nature consciously rather than on autopilot.
Traditional (Hellenistic)
Cancer is the cardinal water sign, cold and wet by the old qualities and reckoned a nocturnal sign. Its domicile ruler is the Moon, so the Moon is the lord of any planet that falls here and of the matters Cancer governs; Jupiter takes its exaltation here. A planet in Cancer must work through the sign's nature and answer to its ruler's condition. As a place in the chart it carries the nurturer, protective and feeling, tending home and belonging.
Lean in — Express Cancer's nature consciously and at its best.
Watch for — Run Cancer on autopilot or only its shadow.
