India's World Cup cricket hero Yuvraj Singh returned home on Monday after receiving treatment for a cancerous tumour in the United States. Sporting a black jacket and red baseball cap, the 30-year-old all-rounder gave thumbs up signs to well-wishers who had gathered at New Delhi airport to welcome him back. "He is absolutely fine and will rest at home for another 10-15 days," his mother Shabnam Singh told reporters at the airport. Left-handed Yuvraj, named man of the tournament after India's World Cup triumph at home last April, was diagnosed with a rare condition, mediastinal seminoma -- a malignant tumour between his lungs -- soon after the event. After completing three sessions of chemotherapy in Boston in March, he had moved to London before returning to India. "Finally the day has come! i am going home tomorrow! cant wait, excited to see my friends and family ..see you india!!," Yuvraj said on Twitter on Sunday. Thousands of well-wishers, politicians, his team mates and other sports personalities including US cycling great Lance Armstrong had sent messages to the ailing all-rounder who is known for his aggressive batting and disciplined spin bowling. "Today the entire country is happy, god is happy and I am very happy. My son has come back as a winner," Yuvraj's father Yograj Singh told the NDTV news channel. Yuvraj, who scored 362 runs and bagged 15 wickets in nine World Cup matches, has not played competitive cricket since taking part in two of the three home Tests against the West Indies in November. He has scored 8,051 runs in 274 one-dayers and 1,775 in 37 Tests since making his international debut in 2000.
