Methods for treating mammary gland disorders
View Patent ↗A method for treating a mammary gland disorder, including hyperplastic, hypertonic, cystic and/or neoplastic mammary gland tissue by local administration of a botulinum toxin to or to the vicinity of the afflicted breast tissue.
1. A method for treating a non-malignant mammary gland disorder associated with hyperplastic mammary gland tissue, the method comprising the step of local administration of between about 10 −2 U/kg and about 200 U/kg of a botulinum toxin type A to the hyperplastic tissue of a mammary gland of a human patient
wherein administration of the botulinum toxin type A causes the regression or remission of the hyperplastic tissue, or reduces the ability of the hyperplastic or hypertonic tissue to develop into a neoplasm, thereby treating the mammary gland disorder.
2. A method for treating a non-malignant mammary gland disorder selected from the group consisting of a breast cyst, sclerosing adenosis, duct papilloma, fibroadenoma, blunt duct adenosis, and proliferative breast disease, the method comprising the step of local administration of between about 10 −2 U/kg and about 200 U/kg of a botulinum toxin type A to a mammary gland of the patient,
wherein administration of the botulinum toxin type A causes a reduction in the size of the breast cyst, sclerosing adenosis, duct papilloma, fibroadenoma, blunt duct adenosis, or proliferative breast tissue, thereby treating the mammary gland disorder.
3. The method of claim 1 , wherein the mammary gland disorder is associated with hyperplastic mammary gland tissue.
4. The method of claim 1 , wherein the local administration comprises between about 10 −1 U/kg and about 35 U/kg of a botulinum toxin type A.
5. The method of claim 1 , wherein the local administration comprises direct injection of botulinum toxin type A into the hyperplastic tissue.
6. The method of claim 1 , wherein said local administration comprises implantation of a botulinum toxin type A implant onto or into the hyperplastic tissue.
7. The method of claim 1 , wherein the diameter of the hyperplastic tissue is reduced by about 20% to about 100% subsequent to said local administration.
8. The method of claim 2 , wherein said local administration comprises between about 10 −1 U/kg and about 35 U/kg of a botulinum toxin type A.
9. The method of claim 2 , wherein said local administration comprises direct injection of botulinum toxin type A into said breast cyst, sclerosing adenosis, duct papilloma, fibroadenoma, blunt duct adenosis, or proliferative breast tissue.
10. The method of claim 2 , wherein said local administration comprises implantation of a botulinum toxin type A implant onto or into said breast cyst, sclerosing adenosis, duct papilloma, fibroadenoma, blunt duct adenosis, or proliferative breast tissue.
11. The method of claim 2 , wherein the diameter of said breast cyst, sclerosing adenosis, duct papilloma, fibroadenoma, blunt duct adenosis, and proliferative breast tissue is reduced by about 20% to about 100% subsequent to said local administration.
12. A method for treating a non-malignant mammary gland disorder associated with precancerous mammary gland tissue that increases the risk to the patient of development of a breast cancer, the method comprising the step of local administration of between about 10 −2 U/kg and about 200 U/kg of a botulinum toxin type A to or to the vicinity of the precancerous breast tissue of a mammary gland of the patient,
wherein the precancerous tissue is hyperplastic mammary gland tissue, metaplastic mammary gland tissue, or neoplastic mammary gland tissue; and
wherein administration of the botulinum toxin type A causes a reduction in the size or activity of the precancerous mammary gland tissue, thereby treating the mammary gland disorder.
13. The method of claim 12 , wherein the local administration comprises between about 10 −1 U/kg and about 35 U/kg of a botulinum toxin type A.
14. The method of claim 12 , wherein the local administration comprises direct injection of botulinum toxin type A into the precancerous mammary gland tissue.
15. The method of claim 12 , wherein said local administration comprises implantation of a botulinum toxin type A implant onto or into the precancerous mammary gland tissue.
16. The method of claim 12 , wherein the diameter of the precancerous mammary gland tissue is reduced by between about 20% and about 100% subsequent to the local administration of the botulinum toxin type A.
