No, I'm not...but you're only referring to someone having a Cancer sun. There are many, many aspects to one's horoscope. For example, a person might have *whatever* as a sun sign, but have Cancer or another sign known for being especially emotional in another aspect of their chart. Pluto has a lot to do with the "darker"aspects of the personality.The 12th house can hold a lot of info about mental health challenges.

I have a Capricorn sun, Aquarius moon, and Gemini rising. I do have Cancer in my 2nd and 3rd houses, but almost everyone is going to have Cancer in some aspect of their chart.
