A woman was six months pregnant when she discovered a lump in her breast which quickly grew to the size of a golf ball.
After initially being prescribed antibiotics by her GP and then paying a trip to A&E, Louise Swain-Hughes, 34, was referred to her local breast clinic for a check-up.
She claimed that she was told by a radiologist that the lump was "nothing to worry about" and was just hormones related to her pregnancy, Wales Online reports.
