Climate Change Drives Rising Cancer Burden in Nigeria, Experts Warn

Published

on

 A growing link between climate change and rising cancer cases is putting Nigeria’s health system under pressure, experts warn, as new data highlights the country’s increasing vulnerability.

Cancer has become one of the world’s leading causes of death, overtaking HIV/AIDS, tuberculosis and malaria combined, according to the World Health Organisation.

In Nigeria, the burden continues to rise, with 127,763 new cases and 79,542 deaths recorded in 2022, figures from the Global Cancer Observatory show.

Breast, prostate, colorectal, cervical and non-Hodgkin lymphoma remain the most common cancers nationwide.

Many of these are shaped by environmental and lifestyle risks — factors that experts say are being intensified by climate change.

Across the country, the signs of environmental stress are evident: soot-laden air in Port Harcourt, extreme heat in northern classrooms, recurrent floods in Lagos and Makurdi, and widespread deforestation.

Health specialists warn that rising cases of cancers with no clear cause may be linked to worsening environmental conditions.

Despite these emerging threats, Nigeria’s climate and health policies often operate in isolation.

Analysts argue the country lacks the integrated policy framework needed to connect environmental protection with disease prevention.

Nigeria has made progress in climate governance, establishing the Climate Change Act (2021), the National Council on Climate Change and the National Climate Change Policy (2021–2030).

The new Climate Change and Health National Adaptation Plan (HNAP 2025–2030), developed by the Ministry of Health, also signals increasing recognition of the climate–health relationship.

However, substantial gaps remain. Nigeria ranks 154th out of 181 countries on the Notre Dame Global Adaptation Initiative Index, reflecting high vulnerability to climate shocks and limited readiness.

The HNAP’s Vulnerability and Assessment projects a 21 per cent increase in disease burden due to climate change — a strain the country’s already fragile health system may struggle to withstand.

Climate change acts as a “risk multiplier,” intensifying both infectious and noncommunicable diseases.

The WHO lists nine key health outcomes threatened by climate change, ranging from respiratory conditions to cancers. Yet Nigeria’s policies continue to prioritise infectious disease response, leaving the climate–cancer connection underexplored.

Experts say stronger coordination between the Ministry of Health, the Ministry of Environment and the National Council on Climate Change is essential to building resilience.

Without such collaboration, well-designed policies risk failing to produce real-world impact.

They also recommend integrating health indicators into climate interventions, including clean energy supply for hospitals, safe medical waste disposal, sustainable equipment procurement and mandatory Health Impact Assessments in environmental approvals.

Such measures, they argue, would ensure climate investments safeguard both the environment and human health.

Public awareness of the climate–health link remains low, but advocates stress that prevention begins with individual and community action from proper waste management to demanding cleaner air and greener cities.

As Nigeria braces for escalating climate pressures, experts warn that cancer prevention must become a core component of the country’s resilience strategy rather than an overlooked consequence.

UK Tests Five-Day Breast Cancer Radiotherapy in Major Trial

Published

The UK is testing five-day breast cancer radiotherapy in a major trial that could reduce hospital visits and treatment costs for patients

The United Kingdom has launched a major clinical trial involving more than 1,000 participants to determine whether breast cancer radiotherapy can be shortened from three weeks to five days without compromising its effectiveness in preventing the disease from returning.

The government-funded FAST-Forward Boost trial, being conducted at 39 hospitals across the UK, will investigate whether a shorter course of radiotherapy combined with an additional targeted dose, known as a boost, can provide effective treatment for patients following breast cancer surgery.

The UK Department of Health and Social Care announced the development on Friday, October 30, describing the study as part of efforts to improve cancer treatment and make care more convenient for patients.

Led by the Institute of Cancer Research in London and funded by the National Institute for Health and Care Research, the study aims to recruit 4,830 participants by 2028.

Those enrolled will be followed up for five years, with results expected in 2033.

If the approach proves successful, it could reduce the number of hospital visits required by patients, potentially saving them 10 journeys compared with the existing three-week treatment schedule.

The department said the shorter schedule could also reduce transport expenses and the time patients spend away from work and family.

It could additionally ease pressure on the National Health Service by freeing up radiotherapy capacity for other patients.

Health and Social Care Secretary Yvette Cooper said the trial reflected the country’s efforts to use medical research to improve cancer care.

“This trial shows how the UK is using our world beating research capabilities to pursue huge improvements and transformations in cancer treatment for patients,” she said.

Why the radiotherapy trial matters

Radiotherapy uses carefully targeted radiation to destroy cancer cells or prevent them from growing.

For many people with breast cancer, it is recommended after surgery to reduce the risk of the disease returning in the treated area.

A treatment boost involves delivering an additional dose of radiation to the area considered to have a higher risk of recurrence, usually the site where the tumour was removed.

The FAST-Forward Boost trial is examining how this additional treatment can be incorporated into a shorter schedule.

Reducing treatment from three weeks to five days could make a considerable difference to patients who must travel regularly to hospitals.

The impact may be particularly significant for people living far from specialist cancer centres, those with limited transport options and patients balancing treatment with employment or family responsibilities.

However, the trial is designed to establish whether the shorter approach is effective and safe for the patients being studied. Its results will be important in determining whether the treatment schedule can become a wider option in clinical practice.

UK expands breast cancer screening efforts

The announcement comes as the British government intensifies efforts to improve breast cancer screening, encourage early diagnosis and strengthen support for patients.

The Department of Health and Social Care said screening uptake among women receiving their first invitation had risen to 63.6 per cent, its highest level in a decade.

Despite the improvement, around four in 10 women invited for their first screening appointment still do not attend.

The government is also working with the National Institute for Health and Care Research and NHS England on studies examining how artificial intelligence could support the analysis of mammograms.

The technology is being explored as a way to assist the assessment of breast screening images, although its role and effectiveness must be established through appropriate research and clinical evaluation.

In addition, the government has partnered with breast cancer charity Breast Cancer Now for three years to help women recognise symptoms, find reliable information and access support after treatment.

Together, the initiatives reflect a broader approach to breast cancer care, combining screening, research into treatment improvements and support for people living with the disease.

For now, the five-day radiotherapy approach remains under investigation. With final results not expected until 2033, the FAST-Forward Boost trial will need to establish whether reducing treatment time can deliver comparable cancer control while maintaining patient safety.
