Los Angeles, Nov 3 (TIWN) Actress Sharon Stone is expected to go under the knife to have a "large fibroid tumour" removed following a misdiagnosis.

The "Basic Instinct" actress will have the surgery 21 years after she suffered a brain haemorrhage and stroke that almost killed her, reports aceshowbiz.com.

While encouraging her fans to seek second opinions from doctors, she said the new growth, which develops in or around the womb, was found in her body after a previous medical misdiagnosis.

Taking to her Instagram Stories with an update on her health, she said that she had "just had another misdiagnosis and incorrect procedure" and went for a "double epidural" to treat her pain. She added the agony grew worse and when she went for a second opinion from a different doctor and they revealed she had a "large fibroid tumour" that "must come out."
