My GP recommended that I get an ultrasound scan, and by the time I found out the results, I was certain that I was about to hear the worst news. So you can imagine my relief when the technician told me that it was merely a lipoma – a benign tumour, made of fat cells, that posed no serious threat to my health. Almost as soon as I found out, all those aches and pains vanished, and I soon started returning to my previous weight.
