if scientists isolate a cancer cause protein is this adjectives and how would that allow them to create a drug?

If the action of the protein contributes to cancer nouns, then yes, blocking the undertaking of that protein would make a appropriate drug target. It is also possible that the inaction of a protein might contribute to cancer development. In any covering, finding one protein that is implicated contained by cancer development is not necessarily the 'magic bullet', since developing cancer requires like mad of things going wrong.
A number of the cancer causing proteins exert their undesired hum by being effectively constantly switched on, surrounded by these cases chemists can create a drug which blocks the protein.
An example would be the action of Gleevec which is used to treat CML
They can be paid antibodies that act against the cancer protein.
Antibodies are more specific and so own less side effects.
The first Monoclonal antibody used for treatment within cancer is Herceptin OR Trastuzumab
All tumor markers are proteins. They are different from one another . Not adjectives to create a drug.
