Oncologists are actually way more specific than even that. Because there are many forms of breast cancer and different treatments depending on the type.
But yeah, oncologists aren’t telling people “you have cancer” the way they might say “you have MRSA”.
Yeah, it's WAY more specific. We got a genetic breakdown, multiple pamphlets on the drugs being used, what they are targeting, and why they work (along with the risks).
Honestly, I think people probably get false impressions because cancer usually hits old people and old people are, frankly, often not reliable narrators.
