Cheating Corrie mechanic Kevin Webster is torn when he discovers his wife Sally is battling breast cancer.
The love rat has been seeing business partner Tyrone Dobbs' wife, Molly, while his wife was fearing for her life.
She secretly visits the doctor who confirms a lump is cancerous.
Kevin and Molly had made plans to start a new life together - then Sally tells him (Michael Le Vell) she has the disease.
He is torn between his wife and two kids or Molly (Vicky Binns) on the ITV soap in November.
According to The Sun, actress Sally Whittaker, who plays Sally, once feared she had breast cancer after finding a lump.
She said: "I was lucky it proved to be nothing but the time spent waiting for results was agonising."
Sally added: "I am determined to do this storyline justice for all the women out there who are going through what Sally is." Producers at the Weatherfield soap are working hand-in-hand with a panel of breast cancer experts and charities to ensure that Sally's story is portrayed as realistically as possible.
A 'Coronation Street' spokesperson added: "Breast cancer is a disease which affects so many women and their families. We are keen to ensure that the storyline accurately reflects the many problems and issues faced by breast cancer sufferers."
Producers uncharacteristically took the decision to release story information earlier than usual to enable the show to work openly and closely with its panel of experts.
