Shannen Doherty is letting the world see the toll cancer takes on someone …

The former Beverly Hills, 90210 star, who is currently undergoing chemotherapy in an attempt to stop her breast cancer from spreading, sat down with Chelsea Handler for her Netflix show and the teary actress revealed her struggles battling the deadly disease.

The former Charmed actress said: "I think what's beautiful and hard and interesting about cancer is that it tears you down and builds you, and tears you down and builds you and it remakes you so many different times."

The 45-year-old star also said, "So the person I thought I was supposed to be or was going to be or who I thought I was six months ago is now somebody completely different."

She added, ''And I realize ''Wow, I really thought that I was so brave and so gracious this entire time and really I was just hiding.'''

Even Handler held back tears during the intimate interview. "I mean alright, hold on a second, f**k," the usually funny lady said.

The full episode streams on Netflix today.
