"Sabina has overcome the first cycle of chemotherapy and immunotherapy very well with no nausea or vomiting and with very insignificant side effects," her brother-in-law Mobarak Hossain Khan said quoting a message from a doctor at the Singapore hospital.

She is under the treatment of Dr Toh Han Chong of National Cancer Centre at the hospital.

Sabina does not have fever now and her liver function is particularly improving. "We have taken off all intravenous hydration and she is eating well," said the doctor in his message.

"Her case was discussed by the board comprising all top doctors involved in the management of lymphoma, including medical oncologist, radiation oncologist, lymphoma pathologist and radiologist," he said.

Before flying to Singapore, Sabina was under treatment at a city hospital.
