Hi @Sweetpetal - I love the circus and monkeys comments. :smile: - and I hope you can ignore it and not let it get to you. Some people can be quite insensitive at this time or may not know what to say and as @Afraser mentioned it could have also brought up some issues for her. But I would keep open communication with your manager as they may be able to set up some separate sessions with the team/staff on how best to support you - because that is what you need right now.
As @Zoffiel mentioned I have been managing a project around work and breast cancer and if you think your colleague could do with some extra support - to support you (wink) :wink: - you could suggest she visits the work and breast cancer section of our website. Your employer might also get some use out of this as well - https://www.bcna.org.au/work-and-breast-cancer/
Good luck and lets hope the monkeys behave themselves :-)
Edited 20/11/2018: Sorry @Sweetpetal / It was the end of the day and I tagged @kmakm instead of you on this comment. I have edited it now.
