Mostly, you can't.
The classical astrological signs are "Sun Signs"; that is the constellation that the Sun WAS in about 2500 years ago. Because of the "precession of the equinoxes", the Sun is actually one zodiac sign earlier now; during Cancer, the Sun is actually in the constellation of Gemini.
But even so, at the beginning of July, the constellation Cancer is very low in the western sky at sunset; since none of the Cancer stars are especially bright, you probably won't see it.
Beta Cancri is the brightest star in the constellation Cancer. Its common name is Altarf.
You can find the planet Saturn in the constellation of Capricornus.
Any constellation is a group of stars that appear to form some kind of pattern, but have no connection with each other. They all happen to be in roughly the same direction from us, but they're all at different distances. So there's no such thing as a constellation's distance from us.
Cancer is a constellation that appears in the northern quadrant of the sky and is visible everywhere except for higher than 60 degrees South latitude. It has a right ascension of 8h 38.96 minutes.
The Tropic of Capricorn is so named because about 2000 years ago the sun was entering the constellation Capricornus on the December solstice. In modern times the sun appears in the constellation Sagittarius during this time. The change is due to precession of the equinoxes!!
You can find a list of them in the Wikipedia article "Cancer (constellation)", under the section "main stars".

If you mean the constellation cancer, there is no such thing as a "distance to a constellation". It just doesn't make sense. A constellation is basically a general direction in space.
Aside from Cancer being the dimmest zodiacal constellation, the planet Mars is in Cancer (as of 4/21/10)
5 stars are there in cancer

"The Crab"
It is Cancer.
Cancer is usually represented as a crab in the constellation. The arrangement of stars form a pattern that resembles a crab, fitting the name of the constellation.
Yes, definitely :-)
