Seems odd they are so noticeable in just 10 months. Mine have been growing for over 50 years. One big growth I thought was a SK turned out to be a large malignant melanoma back in 1992 so it pays to watch them on a regular basis. My derms have never recommended freezing them off unless they are in a sensitive area that can cause problems when rubbing against clothes, etc. Some people on here seem to have them frozen off more often. I believe they told me the would likely grow back. A couple years ago a Derm cut one out which took forever to heal and there are still remnants. Mine are mostly on my back, chest and scalp. I have a couple on my upper arms. Sorry I can't give you any good news. I spent a lot of time in the sun the summer I turned 17 and, I guess, that's what caused this problem. Good luck.
