Dozens of caregivers and cancer patients are marching through the streets of the Kenyan capital, Nairobi, calling on the government to make treatment more affordable and accessible.
The protesters want the president to declare cancer a national disaster.They say if this happens more much-needed resources will be allocated to making cancer treatment more affordable, training oncologists and equipping hospitals.
The government says around 30,000 people die from cancer every year in Kenya.
It has pledged to set up more chemotherapy and radiotherapy centres across the country.
But for many Kenyans the treatment is far too expensive.
Only around 35 oncologists serve a population of 40 million people so patients often face lengthy delays.
Screening for cancer is often happening too late.
