What's more 11-year-old Teagan has already raised more than $5000 for cancer research, and will be donating her long hair to make wigs for kids with cancer.

"She said to me 'I can't take away your pain, but I can support you in this way," Mrs Fuller said. "She's just a gorgeous little soul and this is such a beautiful gesture.

"My hair has already started falling out and while expected, it's confronting, so her support means so much."

Mrs Fuller, 47, was diagnosed with grade 2 infiltrating lobular breast cancer in March. She opted for a double mastectomy, and will undergo four rounds of chemotherapy.

"This type of breast cancer is hard to find," she said. "Usually there's a pea-shaped lump, but mine was more of a long thickening along the breast.

"I work for a radiology company and take mammograms all the time, and see recurrences. That's why I opted for a double mastectomy.

"While I can never get breast cancer again, I can get a secondary cancer. However the chemotherapy reduces the chance of that from 30 to five per cent."

On June 11, Mrs Fuller and Teagan will get their heads shaved at Swirls Curls and Cuts, Corrimal.

"We're incredibly proud of Teagan," Mr Fuller said. "She's aiming to raise $10,000 for Breast Cancer Network Australia, and she's well on her way."
