Basal cell cancer removed, but not all of it. how long can i wait for further treatment?

ASAP: The sooner the better. It is difficult with the holidays looming, but i would not wait. This is important if you had a shave excision, but really important if you had the defect closed with a flap of skin to avoid a deep recurrence of the cancer. Use of frozen section in the or/surgery center and/or moh's excision is advisable. Best wishes!

Ask doctor: If they did biopsy they can schedule treatment once the diagnosis is confirmed. Size, location will dictate treatment options such as excision with primary closure, skin graft or flap. If it is small curettage may be option. If it is large greater than 2 cms. On the face or scalp, or in certain difficult areas such as the eyelids, near the ear, side of the nose mohs may be best option.

Do it right away: If you had incomplete ski cancer removal, you should have further treatment right away. You might even need special treatment called mohs surgery. Without more surgery, the cancer will continue to grow and possibly spread along nerves or lymph channels. The residual cancer will not go away on it's own so get it treated right away.

Sooner better: The sooner you get the skin cancer removed completely, the less chance it has to spread and cause further damage. This will also determine how large the scar will be. Most definitive treatment with highest cure rate is mohs surgery.
