 Hello friends, I am Dr. Rahul Bak, I am a consultant surgical oncologist in department of oncosciences at Manipal Hospital's Baner Pune. As we all are aware that February is in World Cancer Awareness Month, I am going to talk about a very uncommon and very rare skin tumor that is malignant melanoma. As we all know malignant melanoma are dangerous and aggressive tumors, but you should not be worried because not every mole on the skin is cancerous. But what are the dangerous signs of melanoma? So the easy mnemonic for that is ABCDE. It is asymmetrical region with B means irregular borders with variable color shades, diameter of more than 6 mm and E means evolving shapes and sizes. If you have any of these features in your mole, please consult your oncologist for the further test because early diagnosis and early treatment have a better prognosis and can potentially cure you from this deadly disease. Thank you.
