I have a question about skin cancer and a treatment for it. It's called Mohs micrographic surgery and it seems to treat skin cancer before it infects lymph nodes. My question is based on this diagram that shows how the treatment is performed. It appears that Mohs removes the infected cells/growth until they can no longer see any cells in a microscope. Isn't this how all skin cancer patients are treated? For example, my mother had some pre-cancerous moles removed and the Dermatologist just cut the tissue out. Are these procedures the same, aside from Mohs focusing on more detailed extraction, compared to my Mom who just had a bunch of tissue removed (she has a similar scar like this example)?
If anyone has any insight with skin cancer and this type of treatment, I would love to learn more about it. It seems really interesting and I would like to know if it’s an option instead of having a dent in your body like my Mom has.
