How fast can skin mets occur

[Mary L]

I fought skin mets for 5 years. Everytime I would take a break from Herceptin{because of Heart concerns} it would come back. Mine was apparent by the red inflammation that would start on my mastecetomy site and travel across my chest. As soon as I would go back on Herceptin, it would go away. Finally after 5 years of Herceptin I am off Herceptin and cancer free for 3 years. Wish you well. Mary L
