Surgery being undertaken doesn’t mean there’s an intent or expectation to cure: this is your point of confusion. Incurable doesn’t mean “we’ll never do anything to try and help”. 1) Some tumors (brain being one example) cause problems due to the space they take up and the pressure they exert on nearby organs. Removing a large part of the tumor stops this happening, until the tumour regrows. This hopefully means that majority of the patient’s remaining life is mostly free of these problems. 2) Debulking can also help with subsequent treatment, as there’s less tumor to have to be treated.
