Why do doctors choose to do surgery when there is a proven skin cancer cure known as curaderm-bec5?

Beware.: Anytime you see "proven cure" attached to a product, you should be suspicious. Curaderm bec5 is an extract of eggplant, and there is no credible evidence that eggplant is an effective treatment for skin cancer, no matter what you've read on the internet. Not only that, but using these "magical" creams only delays effective treatment (such as surgery), once you realize that you've been had.

What proof?: A quote from the archives of dermatology: "escharotic agents are available as herbal supplements and are being used by patients for the treatment of skin cancer. The efficacy of these agents is unproven and their content is unregulated. Serious consequences may result from their use. ...Physicians should recommend against the use of escharotic agents for skin cancer".

It is a scam: The "scientific" publications you have read have not be published in the actual medical literature. If you have had "amazing results", I am happy for you. However, i could never, ever, recommend this type therapy to a cancer patient without proven data that it might help. Unfortunately, all it will do for a patient is make them poorer.

Not proven: Surgery is the mainstay of treatment for melanoma.

Not proven: There is no "proven" skin cancer cure aside from surgery. Curaderm is an escharotic agent that is widely regarded as a scam, and has been around for decades. Most testimonials you read, people are reporting treating multiple different cancers, basal cells and squamous cells, all over themselves; to have that many different primary cancers would be rare and likely just self(and wrong) diagnosis.
