This is only for one form of skin cancer.
I think the word cancer really is used to broadly and most people believe that cancer = cancer when in fact cancers vary widely. Sarcoma cancer is so different than say Leukemia that one trial that help one has zero impact on the other.
In cancer it is the scientific name that is so important to understand what is happening. I ask people what kind of cancer they have and they say I don't know its cancer my doctor knows and I just cry on the inside.
