Shannen, who is currently undergoing chemotherapy to try to stop the spread of cancer which originated in her breast, tearfully told Chelsea it has forced her to look at herself in new ways - some good, some bad.

The 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. It remakes you so many different times.

'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.

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

'This was very hard and not humbling – because I've already been humbled by cancer.

'It was hard in the sense of rethinking sort of who you are and how you come to terms with who are now and accepting it and looking at your husband and thinking like, ''Dude, I'm so sorry.'''

Shannen said: 'And then there is this lady.... @chelseahandler We met many many years ago. Have run into each other and always exchanged numbers, talked of plans etc. Chelsea reached out and has since, made a point to have date nights with me on a weekly basis. Yeah she's funny but also wicked smart with a huge heart. This one just wants to make a difference. Sometimes the right people come into your life at the right time.'

On Thursday former Beverly Hills co-star Tori Spelling said she admires her castmate's determination to help others in their journeys too.

She told E! News: 'I haven't personally seen her, but I obviously have followed her fight. It's been amazing how she's done it through social media. I give her props for that. I think she's standing up for a lot of women everywhere that are fighting that battle.'

'She's doing a brave and wonderful job, and we obviously support her. We've all been talking and supporting her from afar. It's really hard to know what to do when someone's going through that - if they want people there or not there. But I think she's very brave and I admire her so much.'
