Thank you for the question.
In general, we worry about a mole when it shows the following features:
1. Asymmetry
2. Borders are irregular
3. Colour is variegate or uneven
4. Diameter >0.6m
5. Evolution - the mole is enlarging or bleeding
If there are changes to a mole such as bleeding and crusting, and there are concerns of skin cancer, the mole can be excised and sent for histological testing to rule out a skin cancer or melanoma.
Mole excision is done under local anaesthesia. If in doubt, do visit your doctor/dermatologist who will do a proper examination and advise you further on the need for excision.
