Science will win the technical battle against 1 cancer. But that is only half the fight
The numbers are stark 2. Cancer claimed the lives of 8.8m people in 2015; only heart disease caused more deaths 3. Around 40% of Americans will be told they have cancer during their lifetimes 4. It is now a bigger killer of Africans than malaria. But the statistics do not begin to capture the fear inspired by 5 6 cancer's silent and implacable cellular 7 mutiny 8 9. Only Alzheimer's exerts a similar grip on 10 the imagination 11.
Confronted with this sort of enemy, people understandably 12 focus on the potential for scientific breakthroughs 13 14 that will deliver a cure 15. their hope is not misplaced 16. Cancer has become more and more survivable over recent decades owing to 17 a host of 18 advances 19 20, from genetic sequencing to targeted therapies 21. The five-year survival rate for leukemia 22 23 in America has almost doubled, from 34% in the mid-1970s to 63% in 2006-12. America is home to about 15.5m cancer survivors, a number that will grow to 20m in the next ten years. Developing countries have made big gains, too: in parts of Central and South America, survival rates for prostate 24and breast cancer have jumped by as much as a fifth in only a decade 25.
From a purely technical perspective 26 27, it is reasonable to expect that science will one day turn most cancers into either chronic diseases or curable ones 28 29. But cancer is not fought only in the lab. It is also fought in doctor's surgeries 30, in schools, in public-health systems and in government departments. The dispatches from these battlefields are much less encouraging.
Cell-side research
First, the good news. Caught early, many cancers are now highly treatable 31. Three out of four British men who received a prostate-cancer diagnosis 32in the early 1970s did not live for another ten years; today four out of five do. Other cancers, such as those of the lung, pancreas 33 and brain, are harder to find and treat. But as our Technology Quarterly in this issue shows, progress is being made. Techniques to enable early diagnosis include a device designed to detect cancer on the breath 34; blood tests can track fragments of 35 36 DNA shed from tumors 37. Genome sequencing 38makes it ever easier to identify new drug targets.
The established trio of 39 20th-century cancer treatments - surgery, radiation and chemotherapy 40 - are all still improving. Radiotherapists 41 can create webs of gamma rays 42, whose intersections deliver doses 43 high enough to kill 44 tumors but which do less damage to healthy tissue 45 as they enter and leave the body. Some new drugs throttle the growth of 46blood vessels 47 bringing nutrients to tumors; others attack cancer cells' own DNA-repair kits. Cancer may be relentless 48; so too is science.
The greatest excitement is reserved for immunotherapy 49 50, a new approach that has emerged in the past few years. The human immune system is equipped with 51 a set of brakes 52 53that cancer cells are able to activate; the first immunotherapy treatment in effect disables the brakes, enabling white blood cells 54 to attack the tumors. It is early days, but in a small subset of 55 patients this mechanism has produced long-term 56 remissions 57 58 that are tantamount to cures 59. Well over 1,000 clinical trials of 60 such treatments are under way 61, targeting a wide range of different cancers. It is even now possible to reprogram immune cells 62 to 63 fight cancer better by editing their genomes; the first such gene therapy 64was approved for use 65in America last month.
Yet cancer sufferers 66 need not wait for the therapies of tomorrow to have a better chance of survival today. Across rich and poor countries, the survivability of 67cancer varies enormously. Men die at far higher rates than women in some countries; in other countries, at similar levels of development, they do comparably well 68. The five-year survival rate for a set of three common cancers in America and Canada is above 70%; Germany achieves 64%, whereas Britain manages a mere 52%. Disparities exist within 69 countries, too. America does well in its treatment of cancer overall, but suffers extraordinary inequalities in outcomes 70 71. The death rate of black American men from all cancers is 24% higher than it is for white males; breast-cancer death rates among blacks are 42% higher than for whites. A diagnosis in rural America is deadlier than 72 one in its cities.
Practical as well as pioneering 73
Variations between 74 countries are partly a reflection of 75 76 health-care spending: more than half of patients requiring radiotherapy in low- and middle-income countries do not have access to treatment. But big budgets 77 do not guarantee good outcomes. Iceland and Portugal do not outspend 78 England and Denmark on health care as a proportion of 79 GDP, but past studies show wide variation in survivability in 80 all cancers.
Instead, the problem is often how money is spent, not how much of it there is. To take one example, a vaccine exists against the human papillomavirus (HPV) 81, which causes cancers of the cervix 82in women, as well as cancers of the head and neck. Rwanda started a programme of routine vaccination 83 in 84 2011, and aims to eradicate cervical cancer by 85 2020. Other countries are far less systematic. Vaccinations could help prevent cervical cancer 86120,000 Indian women each year.
Policymakers are not powerless 87 88. More can be done to verify 89 which treatments (and combinations thereof 90) work best. A £1.3bn ($2bn) cancer-drug fund 91 in England, which made expensive new 92medicines easier to obtain 93, did not assess the efficacy 94 of 95the drugs it provided - a huge missed opportunity. Measuring the incidence and survival of cancer, through cancer registries 96, spotlights where 97patients are being failed. Access to health care matters, too: the number of Americans whose cancers were diagnosed at the earliest possible opportunity went up after Obamacare was enacted 98. And prevention remains the best cure of all. Efforts to rein in 99 tobacco use averted 22m deaths 100 (many of them to cancer) between 2008 and 2014. Yet only a tenth of the world's population lives in countries where taxes make up at least three-quarters of the price of cigarettes, as recommended by the World Health Organization.
Taxes and budgeting are a lot less exciting than tumor-zapping proton beams 101 102and antibodies 103with superpowers. But the decisions of technocrats are as important as the work of technicians 104. Cancer kills millions of people not simply for want of scientific advance 105 106, but also because of bad policy.
