Chancres typically show up anywhere between 3 weeks and 3 months after you get the infection. The sores usually last about 3 to 6 weeks and then go away on their own — with or without treatment. But if you don't get treated, you still have syphilis, even if the sores are gone.

How long does a chancre last?

These painless chancres can occur in locations that make them difficult to notice (e.g., the vagina or anus). The chancre lasts 3 to 6 weeks and heals regardless of whether a person is treated or not. However, if the infected person does not receive adequate treatment, the infection progresses to the secondary stage.

Can chancre be cured?

Yes! Luckily, if you treat it early, chancroid can be cured. When caught early, this disease can be treated with antibiotics.
