Yuvraj Singh, the India allrounder, had asked the BCCI not to consider him for selection for the ODI series against West Indies because he has been recovering from what his family has called an "illness that threatened his career," caused by an "abnormal tumour" on his lung.
According to a statement released by his mother, Shabnam Singh, Yuvraj had been troubled by bouts of coughing and vomitting during the 2011 World Cup but had ignored the problem during the tournament, "assuming it was due to stress."
When the problem persisted after the World Cup, Yuvraj sought medical advice and tests revealed "a golf-ball sized" growth on his left lung, the statement said. Initial reports had suggested that Yuvraj "had what in medical terms is called an abnormal tumor called lymphoma. The danger was, we were told, that it could be malignant."
