Read the book Cancer Salves first and look at all the pictures. This book will answer all your questions. If you take the tumor off, without doing systemic cleansing, the cancer will likely spread. If you do the systemic cleansing, you won't need to take the tumor off with bloodroot. I would do the systemic cleansing and go to a dermatologist when the blood is clean to prevent the horrible scarring and months of painful green oozing sores that make people throw up if they see them.
