A global analysis released this week by the World Health Organisation (WHO) says that up to four in every ten new cancer cases could be prevented through changes in behaviour, stronger policies, and public health action.
The findings, published to coincide with World Cancer Day on February 4, 2026, draw on a Nature Medicine study that analysed data from 185 countries and 36 cancer types.
According to the report, about 37% of the 18.7 million new cancer cases in 2022 were linked to modifiable risk factors such as tobacco use, infections, and lifestyle exposures.
“The science is clear,” said Dr Maria Neira, WHO Director of Environment, Climate Change and Health. “A large portion of cancers — particularly those related to tobacco, infections and unhealthy environments — are not inevitable. They are preventable.”
Tobacco remains the single largest preventable cause of cancer, accounting for roughly 15% of new cases globally, the report shows. Other major contributors include infectious agents such as human papillomavirus (HPV) and Helicobacter pylori, which together make up about 10% of cases.
“Smoking and infection-associated cancers continue to take an enormous toll,” said Dr Elisabete Weiderpass, Director of the International Agency for Research on Cancer (IARC), part of WHO.
“Effective prevention is not only possible — it must be prioritised.”
Vaccines, Behaviour Change and Policy Action
One of the starkest examples of preventable disease highlighted in the research is cervical cancer, which is overwhelmingly caused by HPV — a virus for which safe vaccines exist. Similarly, cancers linked to H. pylori infection, which can be treated or prevented through improved sanitation and medical screening, were also prominent.
“We are at a moment where public health interventions — such as HPV vaccination, tobacco control measures, and healthier environmental policies — could save millions of lives,” Dr Weiderpass said.
The WHO analysis also found significant differences in preventable cancer burdens between regions and sexes:
In men, about 45% of cancers were attributable to modifiable factors.
In women, the figure was lower, at around 30%.
Regional estimates varied widely, with areas such as East Asia, Latin America, North Africa and West Asia showing different patterns of preventable risk exposure.
“These differences reflect variation in lifestyles, environmental exposures, and access to preventive care,” said Dr Neira. “This is why tailored, locally relevant strategies are essential.”
Prevention as a Global Priority
The WHO is urging governments and health systems worldwide to scale up proven interventions — from tobacco taxation and public smoking bans to vaccinations and air quality improvements.
“We must shift the focus upstream,” said Dr Neira. “Investing in prevention not only saves lives but reduces long-term health costs and strengthens resilient health systems.”
The WHO study underscores that while cancer remains a major global health challenge, a substantial share of the disease burden — nearly 4 in every 10 cases — could be averted with strategic public health action, political will, and community engagement.

Senate Orders Kyari’s Arrest Over Alleged ₦210 Trn NNPCL Financial Infractions
… As Former CFO Dismisses Missing Funds Claim, Defends Company’s Accounts
A dramatic session unfolded at the Senate on Wednesday as the Senate Committee on Public Accounts ordered the arrest of former Group Chief Executive Officer of the Nigerian National Petroleum Company Limited (NNPCL), Mele Kyari, over his failure to appear before lawmakers investigating alleged unaccounted funds amounting to ₦210 trillion between 2017 and 2023.
The committee’s directive followed Kyari’s absence from an investigative hearing examining 19 audit queries raised against the national oil company by the Office of the Auditor-General of the Federation.
Lawmakers insisted that the former NNPCL chief had repeatedly failed to honour invitations despite several opportunities granted to him.
The hearing took another twist when former Chief Financial Officer of the NNPCL, Umar Ajiya Isa, strongly rejected claims that ₦210 trillion was missing from the company’s accounts. He argued that the figure being cited as unaccounted for exceeded the total revenue generated by the corporation during the period under review.
During deliberations, some committee members urged restraint. Senator Saliu Mustapha and Senator Tony Nwoye informed the committee that Kyari was reportedly receiving medical treatment in Germany and should be granted another opportunity to appear before lawmakers.
Their plea, however, met stiff resistance from other members of the panel who insisted that verbal explanations were insufficient. Senator Abdul Ningi argued that any claim of illness should be backed by documentary evidence rather than mere verbal assurances.
The strongest push for enforcement came from Senator Victor Umeh, who formally moved a motion calling for the issuance of a warrant of arrest against the former NNPCL chief. The motion received immediate support from the committee’s Deputy Chairman, Senator Peter Nwaebonyi.
Nwaebonyi told the committee that granting Kyari another opportunity to appear voluntarily would amount to chasing shadows. He noted that the committee had already convened nine separate meetings on the matter, with three of them presided over by him, without securing the former NNPCL chief’s appearance.
“This is the ninth time this committee is meeting on the 19 audit queries raised against NNPCL. The time to issue a warrant of arrest is now because the committee must conclude its assignment and report back to the Senate,” he declared.
Following a voice vote, Committee Chairman Senator Ibrahim Dankwambo announced the panel’s decision, directing security agencies to ensure Kyari’s appearance before the committee.
“Anywhere Mele Kyari is, he should be arrested and brought before this committee,” Dankwambo ruled.
While the committee intensified pressure on the former NNPCL boss, Isa mounted a vigorous defence of the company’s financial records. He described the allegation of ₦210 trillion in missing funds as impossible, insisting that the figures did not align with NNPCL’s audited financial statements.
According to him, the company generated approximately ₦54.5 trillion in revenue during the period under review, even before accounting for production costs. He argued that it would be mathematically impossible for ₦210 trillion to be missing when the total earnings were significantly lower than the amount being alleged.
“To be clear, if money had gone missing during our tenure, we would not have had the confidence to publish audited accounts. For over four decades, NNPC accounts were either not prepared, not published, or not submitted to the Auditor-General. The fact that audited accounts were released demonstrates transparency,” he said.
Isa also dismissed allegations that ₦5.8 billion was spent on the registration of NNPC Limited, describing the claim as false and harmful. He challenged the committee to verify the matter independently with the Corporate Affairs Commission and the Nigeria Revenue Service.
Warning against the consequences of inaccurate financial allegations, the former CFO said unsubstantiated claims could damage Nigeria’s international reputation and affect investor confidence. He recalled how a previous petition allegedly disrupted efforts to secure about $2.5 billion in Chinese financing for the Ajaokuta-Kaduna-Kano Gas Pipeline project, despite sovereign guarantees backing the deal.
He further urged anti-corruption and intelligence agencies, including the Economic and Financial Crimes Commission and the Nigerian Financial Intelligence Unit, to investigate the allegations thoroughly and establish the facts. “When people claim ₦210 trillion is missing, they should be asked where exactly it went,” he stated.
At the conclusion of the hearing, the committee directed Isa and former Chief Upstream Investment Officer, Bala Wunti, to return in two weeks as lawmakers continue their probe into the audit queries and the financial operations of the NNPCL during the period under review.

“This is great news. Finally, we have reason to celebrate. The court is indeed the hope of the common man,” he said.
He also called on the Delta State Government to assist in facilitating the implementation of the court order and commended community leaders and legal representatives for their efforts.

FG, Ethiopia Finalise Deal To Transfer Over 100 Nigerian Prisoners
More than 100 Nigerians serving jail terms in Ethiopia may soon be transferred to Nigeria as both countries conclude arrangements for a prisoner transfer agreement.
Minister of Foreign Affairs, Bianca Odumegwu-Ojukwu, arrived in Addis Ababa for the signing of the pact alongside the Attorney-General of the Federation and Minister of Justice, Lateef Fagbemi.
The Nigerian delegation was received by Ethiopia’s Minister of State for Foreign Affairs and the country’s Chief of Protocol.
According to Odumegwu-Ojukwu, the agreement is scheduled to be signed on Wednesday.
She disclosed that four Nigerian inmates died during the lengthy process of negotiations, judicial reviews and ratification of the agreement.
“We cannot afford to lose any more precious lives. We are determined to bring home the living,” she stated in a post on her X handle.
The minister identified Kaliti Prison and Aba Samuel Prison as the facilities where the affected Nigerians are being held.
Odumegwu-Ojukwu described the agreement as a product of the longstanding relationship between Nigeria and Ethiopia, anchored on humanitarian considerations, justice and bilateral cooperation.
She said that while the Nigerian government continues to urge its citizens abroad to obey the laws of their host countries and protect the nation’s image, it remains committed to ensuring that Nigerians facing legal challenges overseas are treated fairly and in accordance with established legal frameworks.
The minister added that the welfare and protection of Nigerians abroad remain a key priority of President Bola Tinubu’s administration.
She also expressed appreciation to the Ethiopian government for its cooperation in bringing the agreement to fruition.
