Kenya is facing a growing health crisis as cancer continues to claim thousands of lives each year, with five specific types, breast, cervical, prostate, oesophageal, and colorectal cancers, responsible for over half of all new cases. The National Cancer Institute of Kenya (NCI-K), through its chair Dr. Timothy Olweny, has dubbed these the nation’s “Big Five” cancers, urging swift and aggressive interventions to curb their deadly grip.
Speaking on July 29, Dr. Olweny painted a grim but urgent picture of the country’s cancer landscape. He emphasized that these five cancers alone account for 52% of the 42,116 new cancer cases reported annually, with many leading to premature deaths, emotional devastation, and financial ruin for thousands of families.
“Cancer is not only a health issue but a socio-economic one. Its burden pushes entire households into poverty,” Dr. Olweny stated. “Targeting prevention, early diagnosis, and treatment of the Big Five could drastically cut mortality and improve quality of life.”
Breast cancer remains the leading cancer among women in Kenya, with 6,799 to 7,243 new cases annually. Cervical cancer follows closely, with over 5,200 new cases per year, and is the leading cause of cancer deaths in women. Prostate cancer leads among men, accounting for up to 3,412 new cases annually.
Oesophageal and colorectal cancers are increasingly alarming due to their high fatality rates and rising prevalence across genders. Late diagnosis, poor lifestyle habits, and limited awareness exacerbate the impact of these diseases.
NCI-K is now calling for robust investment in cancer prevention, early screening programs, and equitable access to treatment and palliative care. The institute also seeks increased funding and decentralization of cancer services to bring care closer to the most affected communities.
As the numbers rise, the Big Five cancers stand as a stark reminder that Kenya must move decisively to address this silent epidemic.
