Is squamous acanthoma cancer?
No.
"Squamous acanthoma" or "Basal-squamous acanthoma" are
scary-sounding, technical terms for "age spots" (or "liver spots"),
which are benign skin blemishes.
Such blemishes, although possibly unsightly, may be removed or
even safely ignored.
Occasionally they may return after being removed, which is not
cause for concern.
