Mrs Lehndorf said 141 people had signed up but the aim was to have 200 supporters to reflect the 200 people diagnosed in the region each year.
"It really can happen to anybody," Mrs Lehndorf said.
"I've had a family member go through it and I've had a few scares myself."
The money would all be used to support local women, she said.
The lunch, which first took place in 2013, will be held on August 7 to thank The 200 Club members for their support.
"The whole premise started with the quote 'great opportunities to help others seldom to come, but small ones surround us everyday'," Mrs Lehndorf said.
"It was that old adage of every dollar counts."
Mrs Lehndorf said women who received support recovered better.
"So many people are affected, its not just those who are diagnosed. It's the family, the friends, the workplace. It's a whole community that is diagnosed, so we really believe in getting the community getting together.
"The lunch gives you the opportunity to network with other members, to hear a bit about where the money goes and receive inspiration from a speaker."
Club member Sue Macilwee had taken part in the lunch during the last two years and said the support group was a nice way of giving back to those with breast cancer.
Mrs Macilwee said the club was a great idea as it helped support the families as well as the patients.
