Tina Turner, 81, bids farewell to her fans as she battles

Tina Turner has bid farewell to her fans as she battles cancer.

The singer announced on Instagram that she was being treated for a malignant form of the disease and would be retiring from live performances.

 "I'm going through some stuff right now with my health, but I want you all to know that I love you very much," Tina wrote in a post directed at her fans.

 "My career is over, but our friendship will continue." 

The news comes as a shock following rumours earlier this year that Tina had retired from music altogether.

In May 2017, it was reported that the singer had been forced to cancel several tour dates due to ill health - an unconfirmed report later suggested she may have contracted lupus after breaking her foot in December 2016. 

Since then, reports have continued to circulate about Tina's state of mind and well-being; though no further updates have been released since early June 2018
