In atrology, Cancer refers to those born 23 June through 23 July, and is the fourth sign of the Zodiac. A Cardinal Water sign, Cancer is dynamically emotional. Cancer people are in tune with the feelings of others as they tend to feel things so deeply themselves. Cancers know how to influence others emotionally, but typical Cancers sometimes have trouble balancing their own emotions.

Ruled by the Moon, Cancers can be moody and sensitive yet also very capable at getting what they want. The Moon influences the subconscious mind and intuitive Cancer individuals sense and feel their way through life. If the Moon's emotional force is controlled, stability results, but if the Moon's emotional force is not controlled, the result can be instability for the Cancer personality.

The Crab is the symbol for the sign of Cancer and sometimes the Cancerian displays a brooding sort of neediness, while other times the Cancerian seeks the emotional safety of their own shell. Like the Crab, Cancers tend to react to their environment and can become agressive on the rare occasion when they feel they need to be. The classic Cancer is seldom spontaneous, but very caring and sympathetic towards others.

Cancerians often make excellent child caregivers, nurses, counselors, and social workers. They are often emotionally intelligent and sensitive to the feelings and moods of others. Medicine, marketing, and homemaking are all fields well-suited to the intuitive, thoughtful Cancer. Classic Cancers crave a family and the Moon sign of Cancer is associated with the mother as well as with family life in general.

Silver is the color and metal associated with Cancer. Some astrologers see black, white, and gray as other Cancerian colors. Cancer rules the stomach and Cancerians can be prone to stomach pain when they are upset emotionally. Keywords for Cancerians are family, sensitivity, accomplishment, and emotion.

Sensitivity and understanding flows between Water signs, so Pisces and Scorpio are the most compatible signs with Cancer. Another Cancer, Virgo, Taurus, Leo, Capricorn, and Gemini may also be compatible. Aquarius may be too unemotional for Cancer and Sagittarius too superficial. Cancer may consider Aries too aggressive or insensitive, and a Libra as too indecisive. Famous Cancerians include Helen Keller, Tom Cruise, Pamela Anderson, Lindsay Lohan, and Richard Simmons.
