Not sure I can be of any help. I developed a mole in which I thougt was a deer tick. Turned out to be melanoma. Had it surgically removed and now go yearly for annual mole checks. I've had several moles removed in the past. Was not aware that having skin cancer/malignant moles was even connected to having cancer in the body. This is a good hting no cancer detected in the blood. You did not mention in the lymph section. I had 3 lymph nodes removed during htis melamnoma surgery to ensure a microscopic cell thad not traveled to another part of the body. I saw where no one had answered your question, and I wanted to at least try to put your mind at ease. You are never alone here! Keep in touch and keep us posted!
