For Marcus, a scalp growth associated with acne keloidalis nuchae had affected an ordinary part of daily life: wearing a hat. During a follow-up conversation, Dr. Sanusi Umar confirms that the treatment plan has not changed, while Marcus prepares to say goodbye to the growth that the conversation playfully calls “Mr. Brain.”
A Growth That Changed an Everyday Routine
The chapter begins with a simple practical problem. Marcus is unable to wear hats because of the growth on his scalp. That detail brings the discussion down to the level of everyday comfort, rather than focusing on appearance alone.
People searching for information about bumps on the back of the head may recognize the importance of questions like these. In Marcus’s case, however, the chapter does not provide a new examination finding or a completed treatment result. It documents a conversation about his current situation and the plan ahead.

Dr. Umar Keeps the Plan in Focus
Dr. Umar notes that little has changed since the last visit and that he did not expect a significant change in such a short interval. He makes the next point plainly: “Our plan still remains the same.”
That exchange matters because the conversation is about what comes next, not a claim that treatment has already taken place. The clip does not identify the procedure or establish a final outcome. It shows Dr. Umar guiding Marcus through the decision to move forward.
Saying Goodbye to “Mr. Brain”
The conversation becomes lighter when someone asks whether the growth has a name. The nickname “the Brain” emerges, followed by “Mr. Brain.” Dr. Umar addresses it with a playful warning: “Your hours are numbered.”
Then comes the question that gives the chapter its emotional center: Is Marcus ready to say goodbye? Marcus answers, “Yeah, I’m ready to say goodbye.”
The answer is direct. Marcus is looking ahead, and Dr. Umar’s role is to keep that moment anchored in the treatment plan already discussed. The chapter ends at that point of readiness, without showing what happens afterward.
