A golf event will be hosted at the Stawell Golf Club in her name on Sunday, a fundraiser for the Cancer Council, something close to her heart.

Mrs Mitchell, 64, is battling cancer again, despite beating lung cancer, twice.

"In 2016, I was diagnosed with my first lot of lung cancer," she said.

"I had a really bad pain in my tummy and was sent for a CT scan and the machine captured the bottom of my lung.

"Luckily, it was picked up and they could operate. They removed the bottom lobe of my right lung."

Mrs Mitchell said no other treatment was required outside her three-monthly check-ups.

In October 2018, Mrs Mitchell's life was once again turned upside down.

"I kept having regular tests which would come back all clear," she said.

"I experienced more severe pain on the other side of my stomach.

"My husband kept questioning if I had been to the doctor but I kept saying 'it will be right'."

Mrs Mitchell said tests showed she had cancer in her upper-left lung.

"I had another operation and they also removed some lymph nodes where cancer had spread," she said.

"I had chemotherapy for three months with ongoing tests."

Mrs Mitchell considers herself "lucky" with two cancer diagnosis picked up through scans not directly related to the area where the spots were found.

In 2019, Mrs Mitchell again was sent off for scans which revealed more cancer.

"It was sheer luck again," she said.

"I had a lump in my throat and had a CT scan for that but it turned out to be an infected cyst.

"The oncologist spotted a small spot at the base of my brain from the scan."

Around the same time, Mrs Mitchell said she was experiencing soreness in her back.

"I went for another scan to do some investigation and it was there more cancer was picked up, this time in my adrenal glands which is on top of your kidneys," she said.

"I had radiation for my brain and I started chemotherapy again two weeks ago and also immunotherapy.

"I've lost my hair because of the radiation and I feel pretty tired and nauseous.

"Besides that, I still play golf when I can. I run out of breath because I've basically got one lung left.

"It's important to keep social - being sick can isolate you from the community."

Mrs Mitchell supports her sister who actively raises funds for the Cancer Council's Relay for Life campaign.

"We're hoping people can donate for me to do a lap at this year's Relay for Life," she said.

"I have always been passionate about raising money for the Cancer Council.

"My friend Deb O'Connor battled cancer and she was the motivator for my sister as well.

"We started about eight years ago and my sister's team won the highest fundraiser in its first year."

Mrs Mitchell said she felt honoured to be able to host a day and share her story in the hope to help others.

"A big message is to stop smoking, or don't take it up," she said.

"Even though I gave up smoking ten years ago it's just hit me now.

"When I started smoking there was never any talk of lung cancer and the impact it could have on your health.

"You just never know. I thought I was fit enough playing tennis, golf and going for walks. My diagnosis hasn't been pin pointed exactly back to smoking, but I believe it is.

"Cancer doesn't discriminate for anyone. Look after yourself and if you think something is wrong you must go and get it checked out."

Golfers can still enter and play in a team at the event on Sunday, entries will be taken on the day but early entries can be submitted by contacting the golf club which the club has said would help for catering purposes.

"A fantastic day has been planned and a big thanks needs to go to all the organisers," Mrs Mitchell said.

"There will be a heap of activities for golfers and non golfers.

"People have been so generous in their support of the fundraiser. It's looking like it's going to be a great day."
