Dannii Minogue was so ill after giving birth to her first child, she feared she had cancer.
The singer-turned-reality TV judge told this week (beg10Oct11) how her weight plummeted and she suffered severe tiredness and a bout of appendicitis after son Ethan was born last year (10).
She was eventually diagnosed with an under-active thyroid and is receiving treatment for the condition - and she's now revealed she feared she had cancer after watching her sister, singer Kylie, battle the disease in 2005.
Minogue tells British magazine Fabulous, "In my darkest moments I did really worry - because of family history - it could be something that serious. The last year was incredibly tough."
