I noticed I was bleeding after scratching the other day. It happened again today. No mole before but it's a perfect circle and bleeds easily. Cancer?

Unlikely: What you described is unlikely to be cancer. Could it be that you had in insect bite, e.g. tick bite and the bleeding is from the bite and scratching. Perfect circle also suggest erythema marginatum. It would be prudent to see your doctor for an examination and may be tests for Lyme disease.

How soon after diagnosis should you get a cancerous mole removed? Is one month too long to wait?

How soon after diagnosis should you get a cancerous mole removed? Is one month too long to wait?

Depends: "cancerous mole" could mean a mole which has become malignant melanoma, in which case prompt removal would be really important. It might also mean a mole on the way to becoming cancerous (a dysplastic mole), in which case waiting a month is no problem. I suppose it could also mean a basal cell skin cancer or a squamous cell cancer, both of which could wait a month, especially basal. Ask the doc. ...Read more
