I have seen two medical professionals with differing assertions about the larger dark spot on my penis. I have been told it needs a biopsy, but I have also been told assuredly that it is an age-spot or lentigo. Both have gotten darker, the smaller one more so in recent months. Are they just lentigos or "age spots" ?
They just appear to be ageing spots to me. Have you ever had any pain or unusual sensations at the two areas?
