What are the signs that a mole might be cancerous?

In a report on Pinoy MD, Oncologist Dr. Isaac David Ampil II said when a mole changes its form there may be a possibility that it is cancerous.

"Kapag nagbago yung anyo ng nunal, then kailangan mo na magpatingin sa doctor. Halimbawa, 'yung nunal ay dati maliit pero lumalaki or kunwari dati siya ay flat ngayon ay umuumbok na," he said.

"O kunwari yung nunal mo nagsusugat-sugat na o nagdudugo o yung tinatawag naming nanganganak na nunal, ' yung nagkakaron pa ng mga nunal sa paligid," he added.

According to Dr. Isaac when the mole is transforming into different forms it's a sign that you have to consult a doctor to get it checked. — Jannielyn Ann Bigtas/LA, GMA News
