Cancer With Cancer:

They both take words and actions to be literal truths and that can mean some consistent pain and unrest for them. They tend to see themselves as martyrs, vastly giving individuals, and when one does not see this in the other then the reaction is shock. They will waste a lot of time together, better spent on other things, in the middle of petty bickering and dredging up the past mistakes of the other.

cancer and cancer - astrological compatibility rank = 3 (10 is best)

First thing you need to do is get a manual that tells you who goes first and on what night. Otherwise you are both going to just sit there and wonder. How "did" you two manage to get together anyway? Whose initiative was it and will he or she call again? A movie that needs a director! And by the way, try to avoid those emotional scenes, unless you really are acting.

CANCER goes with Scorpio, Pisces, Taurus and Virgo. (best match is Taurus)

Best Match For Cancer Is Taurus
This is an excellent match and you will find it hard to tear yourselves away from one another! Stay clear of getting too wrapped up in one another though...

Worst Match For Cancer is Gemini
You are too active for this one. The Cancer will want to stay home and cling, so to speak, while you want to go out roam, do things. Forget it! Your energy level is too much higher then the Cancer, and this will in most cases be too much to overcome.
