Almost half of cancer patients diagnosed too late

In a report, the charity claims that 46% of all patients with cancer in England have their disease diagnosed when it has already reached an advanced stage, CNN reports. The findings have highlighted the worryingly high rates of late diagnosis, and consequently poor survival, for people with many types of cancer in Britain and prompted calls for heavier NHS investment in renewed efforts to spot the disease more quickly. Although the situation has improved in recent years, Britain still has one of the worst records in Europe for both identification of cancer and survival from it. Urgent improvements to how soon cancer is diagnosed would save the NHS tens of millions of pounds a year through reduced chemotherapy, radiotherapy and surgery, as well as enhancing many cancer sufferers' chances of survival, CRUK estimates. Currently some areas of England are between three and five times better at detecting certain forms of cancer than others and that variation needs to be reduced, it said. The charity's research found that 46% of all cancers diagnosed in England in 2012 were not detected until they had reached stage three or four, according to its analysis of data collated by the NHS's National Cancer Intelligence Network. Overall, 93% of cases of melanoma (skin cancer) were diagnosed at stage one or two, as were 83% of those found to have breast cancer and 61% of prostate cancers. However, only 23% of lung cancer cases were found at an early stage, as were 32% of cases of non-Hodgkin lymphoma and 44% of ovarian cancers. "Diagnosing cancer at its earliest stages, before it has had a chance to spread to other parts of the body, can have a huge effect on survival", said the charity. "Once a cancer has spread, it is often harder to treat successfully, meaning that a person's chances of surviving are much lower." For example, if lung cancer is diagnosed early, seven in ten patients will live for at least a year but only one in four do so when it is detected late. Likewise, with bowel cancer, nine in ten patients survive for at least five years when they are diagnosed early but fewer than one in ten do so when the disease has reached stage three or four upon identification. Late diagnosis can occur when a patient delays going to see a doctor about symptoms they have developed, or a doctor wrongly judges those signs to be of no concern or believes they indicate another illness, such as irritable bowel syndrome. Some cancers, such as pancreatic cancer, only become noticeable once they have begun to spread, said Sara Hiom, CRUK's director of early diagnosis. However, "for many others there are chances for the cancer to be picked up earlier", she added. Anyone who notices something unusual about their body should visit their GP at once. "GPs play a critical role of course, knowing when symptoms need to be investigated and referring patients promptly for tests," she said. CRUK estimates that, if all parts of the NHS diagnosed cancer as promptly as the best ones do, then the service could save as much as £210m a year and improve 52,000 patients' chances of survival across the 200 different types of cancer.
