I recently had a mole removed and it healed up perfect. the biopsy came back pos. for basil cell. what should i do now?

One : One option might be to have the biopsy material reviewed by another dermatopathologist . Requested outside opinions like this are not that unusual in difficult cases since there are many types of skin conditions that can mimic cancer yet not be cancer. If a determination is not possible, and the lesion is at the margin of resection, re-excision is prudent in the event this was a basal cell carcinoma. At the very least, close follow-up with your dermatologist is important to monitor this area (and the rest of your skin).

It : It typically would still require treatment because the basal cell still exists in the skin and might recur. Typical treatment would be either a topical cream such as aldara, (imiquimod) curettage and electrodessication, surgical excision, or mohs surgery. Depends on the location, size, etc. Of the basal cell. I hope that helps.

Depends: Most of the time additional treatment is required. These tumors often have "roots" so to speak, and despite healing up, there is often residual skin cancer that will come back in a few months to years. Treatment at that time may not be as simple.
