A TEENAGER died after six doctors "failed to spot her tumours" seven times - instead insisting she was just "under the weather". The same dismissive response was delivered by six different doctors on seven occasions. I googled Ruby’s symptoms and read about lung cancer cases where a tumour pressing on a vein in the chest can cause swelling. "So even when a child presents with cancer symptoms, they may not think it’s likely to be the disease." She was only diagnosed with advanced adenocarcinoma after she visited a private doctor and died three weeks later.
