"Infections are the second-leading cause of death among cancer patients, and lead to one in five being hospitalised during treatment. Given that many cancer therapies weaken the immune system, making patients more susceptible to infections, this is to some extent to be expected. But increasingly clinicians see infections that are becoming drug-resistant — antibiotics once effective against them no longer work. Without new and effective antibiotics, this is only going to get worse, with more people surviving cancer only to die of an infection that was previously treatable."
