Tumor size of a dime removed from my leg a yr ago. now there is a black dot at edge where there's a scar looks like a hairfollicle leekin clr fluid ?

Recheck: Having a leg surgery and now a new lesion at the site is suspicious. Best to get reexamined to determine what this could be . Please see your doctor.

Melanoma, BCC or SCC: Basal cell or squamous cell carcinoma or melanoma, or a metastatic tumor of other origins? It might be something benign like an ingrown hair within a follicle, or there is an outside chance that the tumor resection margins were not 100% clear microscopically. It only takes one cancer cell to start replicating, and melanomas are notorious for travelling. Get it checked and perhaps biopsied ASAP.

Needs to be checked.: A pigmented mole which grows back and drains fluid is concerning enough to warrant prompt attention. This needs to be seen by your physician or dermatologist promptly. Be well!
