Scotland's Lynsey Sharp is taking a break from athletics after surgery to remove pre-cancerous cells.
The 29-year-old former 800m European champion was alerted to the issue by a smear test and is urging other women to get themselves checked.
Sharp, who withdrew from last weekend's Scottish Cross-Country Championships, will "take it easy for a few weeks".
"It's too important not to share. The last few weeks have been a bit rough," she wrote on Instagram.
"Last week I had surgery to remove cells which came back today as pre-cancerous.
"If I hadn't gone for a smear test I wouldn't have been able to catch this before it developed any further.
"Please please please go and get a smear test... it takes five minutes. If sharing this encourages even one of you ladies to go then it will be worth sharing."
