Japanese swimming sensation Rikako Ikee posted fresh messages on social media to her fans on Wednesday. A day earlier she tweeted that she has been diagnosed with leukemia.
The 18-year-old's updates of her accounts on Twitter and Instagram noted her gratitude for people's support.
She wrote "Many people have told me that they've registered to become bone marrow donors or that they've donated blood. Those messages give me hope and encourage others who are suffering."
She also wrote "I believe that God won't give me more than I can handle. I believe there is no wall I cannot scale. Of course I prize my life as a competitor in swimming, but now I will patiently focus on a full recovery from the disease while receiving support from the people around me. I wish to thank you all again for your messages and support. I will come back."
Ikee holds the national record in multiple events, including the women's 100-meter butterfly. She is widely tipped to scoop up medals at next year's Tokyo Olympic Games.
The Japan Swimming Federation says Ikee had been training in Australia since last month, but returned to Japan in early February after complaining of poor health.
She is now in a hospital.
