Since childhood I seems to have a lesion on my head scalp. My parents told me it's inherent and I was under the impression that it's a wart/mole. With age it has grown a little and it's of the size of a peanut with my age as 29. I consulted a doc who said it's a sebaceous cyst another doc told me it's soft lipoma/polyp. It does not itch or pain. Does not show the symptoms ABCDE. I do not wanna remove it as it may grow back bigger and I'm.scared of surgery. Request you to suggest if this can be cancerous.
