Widely Variable: Melanoma grows and invades at widely variable rates. It really is not possible to give a useful estimate to your question. As a dermatologist, I have seen melanomas that took 5 yrs to grow that deep and others that seemingly appeared to invade almost immediately. Any suspicious mole should be checked out immediately. Good luck to you.

A guess: Melanomas can behave quite differently. Some can stay relatively dormant for years, while others grow like wild fire. I would estimate that a superficial spreading melanoma (the most common type) would reach 0.5 mm in depth in about 6 months to 2 years from its inception.
