Mars in Cancer works best in an environment where others can offer support and backing. They will assert themselves in an indirect manner, and avoid direct confrontation as much as possible. Fearing they will upset those close to them, emotional bonds are maintained at the cost of expressing their own feelings and needs.

They may also be known for their extreme patriotism and emotional loyalty and have powerful emotions, but don’t always act in the best interests for the self. Sometimes anger leads directly to the stomach (ruled by cancer) and stomach upsets, ulcers and general sensitivity in this area is common.
Men with this placement can be quite smothering and overly protective in relationships, and infidelity would threaten their security or violate the feeling of belonging to someone else. Women may be attracted to men who are sensitive, nurturing and affectionate, a good provider. This combination is known for its smouldering moods, and they become easily upset, volatile and capable of dragging others into his or her guilt or hurt. Mars in Cancer tends to hold on longer than others and they have deep and intense needs for emotional security, and puts emotional pressure on others through bad moods, sulking and feeling easily slighted. Sexual relationships need to provide them with reassurance that they are wanted and needed, and above all, they need to feel safe.

Mars in Cancer has a tendency to take attacks personally and will react in an over-defensive manner once their feelings are engaged; sometimes Mars in cancer feels vulnerable and weak and has a hard time dealing with their acute sensitivity in this area.

“If you really want to understand Mars in Cancer, spend some time observing a crab. Some years ago I watched one coaxed out of its hiding place by a bait. It moved cautiously forward, and then rushed back to its underwater hole. Then, after a time, it sidled forward from another angle, and again quickly scuttled back. When it did finally grab the bait, it moved with astonishing speed and force, claws opening closing down on the food, and then it disappeared for good in a cloud of unsettled water. Think of that crab when it annually loses its shell, and spends a brief time utterly without protection. Mars in Cancer hearkens back to a time when we were utterly vulnerable, unable to survive without a mother’s care. Somehow this Mars placement never loses its sense of vulnerability. It often leads to inner work, because it demands the integration of feeling and action with a real dialogue between the masculine and feminine sides of the self. Have you noticed that most us feel wounded in some way? Our hurts and grievances tend to be at the centre of our interpretation of the world…Those with Mars in Cancer usually don’t intentionally want to hurt others, but their defensiveness can come across as moodiness or nastiness.” The Mars Quartet
