Cancer tumours are rare in children so, without a big patient population, there is less of an incentive for pharmaceutical companies to conduct clinical trials.Cancer tumours are rare in children so, without a big patient population, there is less of an incentive for pharmaceutical companies to conduct clinical trials.
This means they risk missing out on innovative treatments which target the cancer cells, leaving healthy ones alone.This means they risk missing out on innovative treatments which target the cancer cells, leaving healthy ones alone.

"The cost of developing these gene-targeted drugs is very high. They tend to go to adults first, where more people are being treated and results can be seen more quickly."The cost of developing these gene-targeted drugs is very high.
