The storyline begins as Maria (Samia Ghadie) seems distracted and short-tempered at work and with her loved ones.
When Marcus (Charlie Condou) decides to tackle the matter by asking Maria what's up, she finally confides in him by revealing that she has been referred to a clinic about a lump in her breast.
Maria adds that her appointment is that day, but she'd originally wanted to keep quiet about it until she knew what she was facing.
Marcus immediately insists on joining Maria as she faces the doctors, so they head off secretly without telling Jason or Aidan what is going on.
In the end, the tests are inconclusive and when the pair head back to the street, it's clear that Maria is terrified over what could lie ahead…

Coming up on Emmerdale, Jai Sharma is forced to miss Rachel Breckle's baby scan as the pressure to keep their big secret intensifies.
