will it spread

i had a melanoma on my ankle which measured 1.15mm.i had 3 lymph nodes removed and microscopic spots were found on 1 of them,the doc then took another 11 nodes out and some tissue near my stomach and some more skin from around the original site on my ankle.the 11 nodes and tissue came back clear but the skin on my ankle had more cells found in it.the doc said it should be fine, he thinks i got it at the right time and im very lucky,BUT i was put on a trial for interferon but i was given the observation arm instead of the treatment,i now want to pursue the treatment insead of just observation i want to try and do everything i can to prevent it from comming back wat do u suggest?

Well it over a year. I had my melanoma over two years ago.  So far all okay.  How are you doing?  Hope all is well.
