Veteran actress Dame Maggie Smith is reported to be suffering from breast cancer.
The double Oscar-winner is said to have has also completed a course of chemotherapy while filming her role as Minerva McGonagall in the latest instalment of the Harry Potter films.
"She is dealing with it in her typically brave and understated way," The Sun quoted a friend, as saying.
"She has had a tumour removed and completed a course of chemotherapy.
"This was precautionary and the prognosis looks good. The last thing she wants is fuss," the friend added.
However, a rep for the 73-year-old actress, who has been performing on stage and screen for over 50 years, refused to confirm her illness.
"We never comment on our client's private lives," the rep said.
