The major problem is that the many different facets of the different types of cancer cannot be easily addressed with simple advances in cancer treatment technologies. There are many different types of cancer, people react differently to different treatments, so developing a one size fits all cure will probably always remain difficult.

But sometimes treatment does not work well or stops working. Maybe treatment ended a while ago and was successful at first, but cancer has come back. Or maybe one type of cancer treatment has stopped working and the cancer has kept growing.
Why does cancer not have a cure yet?
Every cancer is caused by a different set of mutations and as the tumour grows, more and more mutations accumulate. This means that every tumour has an individual set of mutations, so a drug that works for one cancer patient, might have absolutely no effect on another.

For some cancers, if it has not recurred by five years after initial diagnosis, the chance of a later recurrence is very small.

Secondary prevention controls cancer by screening to detect the disease at its earliest stages and, if necessary, intervening early in the course of the disease’s progression. Secondary prevention has helped bring down death rates of breast, cervical, and colorectal cancers, among others.
What is implementation science?
Just as crucial will be translating new scientific insights into public health practice —a field known as implementation science. “Public health impact is efficacy times reach,” says Karen Emmons, professor of social and behavioral sciences at the Harvard Chan School. “We often develop interventions without thinking about the end users and what could get in the way of true impact, so shame on us as a field. As a scientific community, we think, rather arrogantly, ‘Well, we’ve shown that colorectal cancer screening is important—why don’t community health centers just make sure that everybody has colorectal cancer screening? It’s clear that vaccines are important—why aren’t all kids getting HPV vaccine?’ But the real question is: How do you structure systems to make those goals possible?”
