A 3-year-old girl from East China's Shandong province has become the youngest breast cancer survivor after undergoing treatment at a hospital in Nanjing, East China's Jiangsu province.

In March, the mother of the girl Yanyan noticed some red and sticky stains on her singlet and in the following days, the stains frequently appeared on the girl's clothes.

The mother became more scared when she found there was something on the girl's left chest, and the lump was soft and could move slightly. The mother took the girl to hospital for examinations.
