Some cancer treatments work great, but they can't breach the outer barriers of tumor clumps. As such, they're only approved for things like blood cancer.
This new treatment acts like a breacher charge, binding to one of the tumour's outer barrier cells and triggering cell death, thus creating an access point.
So this new treatment could allow us to use those other treatments for additional cancer types since now they can get into the tumor clumps?
It's cool that this could be a thing and has been demonstrated to work in vitro, but a lot of these drugs die off because they simply aren't effective (or safe to use) in vivo, so I'll hold my judgement until we see it working in live subjects.
As much as I believe big pharma are unscrupulous bastards, cancer kills people. They want us nice and alive with chronic conditions that need management.
Also if they actually cure cancer, they will use that as leverage to be cunts till the end of time.
