The Aubin Grove resident’s father died in 2009 after a battle with the disease.
Ms Connolly’s family was hit hard again, with her mum diagnosed with the disease early last year.
“This is one of those rare statistics where myeloma occurs in families,” Ms Connolly said.
“There are many unanswered questions because it is so rare. In Australia about 1500 people are diagnosed with the disease each year.
“My mum doesn’t have much time so we’re very keen to help push the research along.”
Ms Connolly will join thousands of others taking part in the Leukaemia Foundation’s World’s Greatest Shave event between March 10 and 13.
The event has been held since 1998 and helps raise money for blood cancer research by encouraging people to shave or colour their hair.
Ms Connolly will be at Bunnings in Cockburn Central on Saturday to shave her hair.
Bibra Lake resident Kerrin Brown will also be colouring her hair in honour of her son Marley and his friends with blood cancer.
