Cancer compatibility
Traditional astrology reads compatibility from the elements before anything else. Cancer is a water sign, so it is read as sharing a temperament with the other water signs and as pairing well with the earth signs.
Everything else falls outside that rule — which is not the same as being incompatible. It means the element heuristic has nothing to say, and the rest of two charts decides it. A sun sign is one placement out of ten.
Same element
The other water signs. Shared temperament — the same way of taking in and giving out energy, which reads as easy recognition and, just as often, as the same blind spot twice.
Paired elements
The earth signs, which the tradition pairs with water. Different temperament, held to be complementary rather than similar.
Outside the rule
Outside the element rule. The tradition offers no general verdict here, so neither does this page.

Why: the water and cardinal families
Cancer shares the water element with Pisces and Scorpio. Signs of the same element are traditionally read as sharing a basic temperament — the way they take in and give out energy — even where the rest of the chart differs.
Cancer is cardinal, alongside Aries, Libra and Capricorn. Modality describes how a sign meets change: cardinal signs start things, fixed signs hold and sustain them, mutable signs adapt and let go. It cuts across the elements rather than following them, which is why two signs can share a temperament and still handle change differently.
