Welcome @cam108, I'm tagging fellow caregivers who have experience with squamous cell carcinoma of the scalp like @gaybinator and @sylviapf. They can share their experiences with you.

As you may know already, squamous cell carcinoma is the second most common type of skin cancer. It’s more common in people with fair skin and on areas of skin heavily exposed to the sun, including the scalp. Squamous cell cancer is generally very treatable and curable when found early. Mohs surgery is typically used when this type of cancer appears on the head or neck.

Cam, I can tell that you are very worried about your father and concerned about making the right choices considering his age and other conditions. I think you are asking all the right questions that you (and he) should discuss with his care team. I would ask questions like:
- What stage is the cancer?
- What is recovery from Mohs surgery like?
- Can the lesion be completely removed with surgery or are other treatments necessary?
- How many appointments will my father have?
- What will happen if he refuses treatment?
- How can he be kept comfortable and pain free?
- Is palliative care available?

What questions would you add? Do you accompany your father to his appointments?
