Cancer is a group of diseases that we may never be able to cure completely, but scientists are optimistic that vaccines, personalised medicine and smart lifestyle choices will help prevent and treat a much greater proportion of cases than currently happens.
Nosotros asked three cancer experts - Nobel laureate Professor Harald zur Hausen, Professor Walter Ricciardi and Dr Elisabete Weiderpass – for their thoughts on curing cancer. They all sit on the EU's Horizon Europe mission board for cancer and will help to define a concrete target for Europe in this expanse over the next decade.

'Prove of infections linked to cancer provide promise of preventing up to half of all cancers'
If nosotros can always cure cancer completely – that is an open question which I cannot respond. We have a practiced chance of drastically reducing the incidence of cancers, but what nosotros run across at present is that the incidence, or occurrence, of cancer is increasing globally.
The mortality of cancer patients is slightly decreasing, but the increase in incidence is not compensated by the decrease in bloodshed. There are notwithstanding a big number of cases coming up every yr, and if we really want to exercise something against cancer in the future, we demand to end the increment.
We know at that place are a number of cancer risk factors that can exist avoided. At this moment, we also know of nearly twenty% of cancers where infections are involved. Nosotros tin can not merely effectively immunise patients against these types of cancer, but nearly eradicate information technology, in detail Hepatitis B (a cause of liver cancer) and Human Papillomavirus (which Prof. zur Hausen discovered is linked to cervical cancer) where we have vaccines that are presently bachelor.
We believe nosotros have evidence that at to the lowest degree thirty% more human cancers are as well linked to infectious events. This provides at least the hope that in the about future other methods tin be developed that volition also lead to long-term protection from those diseases – specifically colon cancer, breast cancer, and prostate cancer, where testify is mounting that specific infectious events play a role.
Recently, we discovered a completely new class of infectious agents which are derived originally from plasmids. Plasmids are a kind of mini-chromosome of bacteria, which nosotros detect in a very large number of colon cancer patients. These are infections which persist for decades, causing chronic inflammations, and these inflammations are actually the crusade of oxygen radicals and mutation events in cells that are susceptible to cancer development.
Nosotros accept all the (plasmid) genomes sequenced that we have identified so far, and what came up was actually a surprise for us, because they do non stand for viral nor bacterial sequences. They are slightly modified bacterial plasmids, originating from specific bacteria only learnt to replicate independently in cattle and human cells. We can demonstrate that they are found in inflammatory lesions of the colon, breast and prostate. So, in my opinion, this will hopefully allow new approaches for prevention and, in the long run, for treatment of these very common types of cancers.
The biggest claiming is to develop more basic research and put more than emphasis on preventative measures to block the incidence of cancer occurrence, avoiding the precursor lesions of cancer with surgical interventions. Nosotros demand to ameliorate the treatment protocol for the curing of cancers. And we demand to devise some methodology in order to attain long-term protection of patients, for a lifetime.

'Digital applied science can help us find more than precise ways of tackling these diseases'
Cancer is a general definition for a series of diseases, and so we cannot take a general approach – a solution for every type of cancer – just nosotros tin can develop a general strategy. It needs an alliance between the different stakeholders, not simply in the health sector, but likewise in the social sector, because many of the behaviours that favour the onset of cancer are modifiable by lifestyle and prevention. We besides have to take advantage of the immense progress in engineering. I'm confident nosotros are going to find a better approach to tackle this illness.
Nosotros take the possibility via digital technology today to take a lot of data that, in principle, could be related to genome sequencing, since, equally far as we know, at that place are some cancers that are genetically determined. Nosotros know that the majority are related to five factors, four of which are behaviours – alcohol use, tobacco employ, eating too much, and not doing enough physical action, every bit well equally pollution. Digital technology can incorporate a lot of data, going from the very general to the specific characteristics of a single person.
Agreement someone'southward specific characteristics means that we can develop a more than personalised and precision-targeted approach, avoiding what happens now – where we provide a single drug, say for every kind of breast cancer. We know that produces side effects in some women who don't get whatever real reward from the drug. So, looking at a subpopulation of women who go breast cancer, that is the approach nosotros accept to develop.
Immunotherapy (where the patient's allowed organization is stimulated to attack the cancer) has also been achieving incredible results. In the past, some cancers like lung cancers or metastatic melanoma were impossible to treat, where at present we have the possibility to really care for them and, in some cases, to accept a substantial solution to the illness. I think we tin can be optimistic besides on this front end.
The claiming for the time to come is the immense data that we will have – genomic data for 500 1000000 (European) citizens – that has to be managed appropriately, with respect to privacy.

Cancer is a family of diseases. In that location are over a hundred dissimilar cancer types. Some types are curable, and indeed are beingness cured, specially when they are detected earlier and in rich countries, while other types nosotros simply don't know how to cure.
For some cancer types, let's say early on stage breast cancer, testicular cancer, and some types of leukaemia, we already know ways to diagnose it relatively early, every bit well equally ways to treat it extremely effectively.
There are several cancer types where very substantial progress has been made, simply there are several types that nosotros don't know how to deal with. At that place is a very mutual cancer type, prostate cancer, where nosotros however do not know the best means to detect information technology early and if information technology's worthwhile to detect it early. Nosotros don't have expert screening tools and we don't know how to differentiate betwixt wearisome-growing types that do not need much intervention at all and rapid-growing types. So prostate cancer is definitely one cancer where we have a very big challenge in terms of public wellness because it affects a very large number of men.
With the enormous increase in the number of cancer patients expected over the next decades due to the increment in life expectancy, governments are called to urgently and more than rigorously implement cancer prevention and cancer control programmes as thirty-40% of cancers are preventable (in European countries; for other countries the proportion of preventable cancers is even college).
What ordinary European citizens can do is learn the European Lawmaking Against Cancer. These are 12 ways, based on very solid evidence, to help reduce your cancer take chances and to help detect certain cancers early.
For case, smoking remains responsible for one-half of all preventable cancers in Europe. An inappropriate diet which does not have enough fruits and vegetables and a nutrition that leads to obesity are other important causes of cancer in Europe.
Equally told to Ethan Bilby.
The interviews accept been edited for clarity and length.
xix/ix/19 - This story has been updated to reflect that thirty-40% of cancers are preventable in European countries and that in other countries the rate of preventable cancers is even higher.
The telescopic of the Horizon Europe Mission on Cancer will be nether discussion on 25 September at the EU's Research and Innovation Days event in Brussels, Belgium.
European Inquiry & Innovation Days
The European Inquiry & Innovation Days, which will take place in Brussels, Belgium, from 24 to 26 September, are designed to bring together policymakers, academics, industry, civil society and entrepreneurs to talk over how research and innovation can help tackle the major issues facing the EU over the next decade.
The thought is to seek a wide range of opinions from experts and interested parties virtually priorities for the start four years of the European union'due south upcoming €100 billion enquiry funding programme, Horizon Europe. In addition to briefing sessions, policymakers from the EU and national administrations will be bachelor throughout the event in a infinite chosen Horizon Village to get together farther input from participants.
The event, which is set to be an annual matter, consists of a policy conference to shape the Horizon Europe piece of work programme, an innovation hub for innovators and investors to network, and a public exhibition called Science is Wonderful!.
