I felt a smooth hard lump in the upper wall of my mouth in back of my upper front teeth. Also, upper front gum was reddish looking. I went to the dentist (I have not seen a dentist in over 20 years). The gum specialist did the biopsy and the results went to my family doctor. He said the results was melanoma, one of the deadliest skin cancer disease. I will be having an MRI to find out where it is. He mentioned 4 stages and I wanted to know what they are. Also, what are the symptoms for each stages. This is my first time and hopefully the last.
