1. A method for treating a lesion of the skin of a patient, wherein said lesion is Bowen's disease or verucca senilis, said method comprising topically administering to the skin lesion a pharmaceutically effective amount of a polyphenol composition comprising (i) a mixture of polyphenols and (ii) a carrier, wherein the composition comprises from about 5% (w/w) to about 20% (w/w) of the mixture of polyphenols, wherein the mixture of polyphenols contains epicatechol, epicatechol gallate, epigallocatechol, epigallocatechol gallate, and gallocatechol gallate. 2. The method according to claim 1, wherein the patient is a human. 3. The method according to claim 1, wherein the polyphenol is isolated from tea or a tea extract. 4. The method according to claim 3, wherein the tea is a green tea. 5. The method according to claim 3, wherein the tea extract is a green tea extract. 6. The method according to claim 1, wherein the mixture of polyphenols contains (−)-epicatechol, (−)-epicatechol gallate, (−)-epigallocatechol, (−)-epigallocatechol gallate, and (−)-gallocatechol gallate. 7. The method according to claim 1, wherein the mixture of polyphenols contains about 2-20% (w/w) epicatechol, about 2-20% (w/w) epicatechol gallate, about 1-25% (w/w) epigallocatechol, about 40-75% (w/w) epigallocatechol gallate, and about 0.5-20% (w/w) gallocatechol gallate. 8. The method according to claim 7, wherein the mixture of polyphenols contains about 10.8% (w/w) of (−)-epicatechol, about 6.5% (w/w) of (−)-epicatechol gallate, about 9.2% (w/w) of (−)-epigallocatechol, about 54.8% (w/w) of (−)-epigallocatechol gallate, and about 4.0% (w/w) of (−)-gallocatechol gallate. 9. The method according to claim 1, wherein the mixture of polyphenols is combined with an additive. 10. The method according to claim 9, wherein the additive is selected from the group consisting of petroleum jelly, wax, oleyl alcohol, propylene glycol monostearate, propylene glycol monopalmitostearate, and isopropyl myristate. 11. The method according to claim 1, wherein the polyphenol composition contained in a carrier is selected from the group consisting of an emulsion, a gel, a cream, and an ointment. 12. The method according to claim 1, wherein the method for treating said lesions is combined with a different anticancer treatment. 13. The method according to claim 12, wherein the different anticancer treatment is selected from the group consisting of surgery, electrodessication, curettage, excision, Mohs micrographic surgery, radiation, proton therapy, chemotherapy, photodynamic therapy, cryosurgery, laser, immunotherapy, vaccine therapy, and biologic therapy. 14. The method according to claim 1, wherein the composition comprises about 15% (w/w) mixture of polyphenols. 15. A method for treating a lesion of the skin in a patient, wherein said skin lesion is Bowen's disease or verucca senilis, said method comprising topically administering a pharmaceutically effective amount of a polyphenol composition comprising (i) a mixture of polyphenols and (ii) a carrier, wherein the composition comprises about 15% (w/w) mixture of polyphenols, wherein the mixture of polyphenols contains about 10.8% (w/w) of (−)-epicatechol, about 6.5% (w/w) of (−)-epicatechol gallate, about 9.2% (w/w) of (−)-epigallocatechol, about 54.8% (w/w) of (−)-epigallocatechol gallate, and about 4.0% (w/w) of (−)-gallocatechol gallate.
