I am new to this site, so I apologize if there are similar posts. Just this morning I felt pain in my palm like it was bruised. I noticed a lump on my palm between the base of my thumb and pointer finger. It is swollen and tender to the touch and is about a centimeter around. It is not bony, and follows right along the life line in my palm. It is not perfectly circle. I am 24, female and healthy. I am though at high risk for skin cancer due to several moles and I have a bony lump on my head as well which I have had a cat-scan for. (The doctors said it was 'normal') I am hoping this is not related. It is definitely under the skin and not on top of the skin like a mole.
