A Scottish teenagee has "bizarrely" suffered from cancer symptoms since her identical twin was diagnosed in 2017 - despite not having the disease herself. Megan Walker's sister Sophie was diagnosed with a Wilms tumour - a type of kidney cancer - on October 25, 2017, and started a four-week course of chemotherapy shortly after.
In the five years since, the 16-year-old has gone into remission twice - but relapsed four times. Throughout this time, Megan has been experiencing many of the same symptoms.
After Sophie was diagnosed following stomach bug-like cramps, Megan began experiencing similar traits of the condition - including stomach and back pain, paleness and even weight loss.
