Sounds like he is taking the proper steps, but if you have doubts perhaps get a second opinion form a medical oncologist such as Dr. Mark Scholz or Dr. Richard Lam in Marina del Rey CA.
They do phone consults.
If I recall you are in UK, and your dad is in Moroco. I do not know who to point you to there.
