Harry: Is it getting bigger?

Ahmed: Yes, and it's very itchy. Is there anything that I can apply to it?

Harry: No, you're not going to apply anything. You're going to go to your doctor tomorrow morning because if you've got a black wart as you call it and it's enlarging, you must always have it checked out. This may be a mole, and I don't want to alarm you but if a mole is enlarging we always get worried about the possibility of cancer in that mole. However, let me reassure you that the chances are that it's not cancerous. But if that black wart is enlarging, changing colour, becoming irregular in its outline, itching, causing pain or bleeding - it needs to be checked. This is quite common in South Africa and is often aggravated or precipitated by the sun. The sun in South Africa is poison and if you tell me that you're a person who loves the sun …

Ahmed: Yes, I'm a great outdoor person.

Harry: Well with that combination of sun exposure and this black wart enlarging , please don't waste time. You go and report to your GP tomorrow morning and he will be able to tell what is what.
