Yuraj Singh Cancer: Indian Cricketer, Receiving Chemo in U.S., 3 Other Athletes Who Endured Cancer

Yuraj Singh, the famous Indian cricketer, has been diagnosed with cancer after doctors reportedly discovered a Stage-1 tumor in his left lung.

Tests revealed that Singh has a rare form of cancer called mediastinal seminoma. He is currently undergoing chemotherapy in the United States. The tumor is in between his lungs, but it is not considered lung cancer.

Dr. Nikesh Rohatagi of the Max Cancer Centre in Dehli has been monitoring the situation and treating Singh. Rohatagi reportedly said that Singh's illness is curable.

It is located between the two lungs, rather than in the lungs. It's a rare disease but something which can be cured. I am confident he will be cured and return to cricket, reported BBC.
