Scientist Abdul Qadeer Khan may have cancer

A team of senior doctors on Friday carried out tests for Pakistan's nuclear scientist Abdul Qadeer Khan, who is under treatment for cancer at a private hospital in the port city of Karachi, according to local media reports.

Abdul Qadeer Khan, is suffering from prostate cancer, which was diagnosed following a routine medical check-up in early August, according to the government.
The scientist, a national hero in the eyes of many Pakistanis, has been kept under virtual house arrest since 2004.

He was shifted to Karachi's Aga Khan Hospital on Thursday.
TV channels reported that Qadeer is expected to be operated sometime on Saturday.
Many Pakistanis appreciate Andul Qadeer Khan's role in developing the country's nuclear arsenal and helping to counter the threat from their nuclear neighbor India.
