Thank you for your query at AskTheDoctor.com
I understand your concern.
From the image that you have shared, I could appreciate a sore and not a swelling, definitely not a wart.
Warts are caused because of HPV infection, whereas such sores are common due to herpes infections. If you had any exposure to someone who is infected or have previous history of such outbreak of sores then there is nothing to worry about. There are 1-2 outbreaks such as this and then the virus automatically stops.
Please do not worry about it turning into cancer. Even warts due to HPV can be treated and never turns into cancer. Please let me know if you have any known history or exposure to herpes before in the follow-up.
Hope this was helpful,
