When Jodie Guerrero felt a pain in her right shoulder, she brushed it off. Maybe she'd strained something carrying her toddler, or it could've been down to the stiff window she'd pushed open the day before.
The ache was intense, but like most busy mums juggling a full-time job and two small kids, she didn't have time to dwell on it.
When the pain mysteriously disappeared a month later, she chalked it up to a minor muscle issue and moved on.

But the reprieve didn't last. A creeping fatigue settled in. And no matter how early she went to bed or how many cups of coffee she drank at work, she couldn't stay awake.
"Fatigue is a tired feeling that never seems to go away," Jodie said.
Then she felt the lump. She was weaning her youngest daughter when she noticed it, deep in the tissue between her right breast and underarm.
Terrified, she rang a breast cancer hotline who urged her to see a GP immediately. That doctor assured her it was just an inflamed lymph node from an infection. Jodie was relieved, but the lump didn't go away.
And before long, new symptoms popped up. Night sweats drenched her sheets, infections came one after the other and her lower right back began to throb relentlessly. The pain ran down her leg to her foot. Even sitting became a challenge.
