If you'd like to understand how HER2+ (pronounced "her two positive") breast cancer is different from other breast cancers, and to understand the experimental drug TDM1 I am taking to treat it, this video about Herceptin is a good place to start.

HER2+ breast cancer is an aggressive, fast-growing form of breast cancer that afflicts around 20% of breast cancer patients. Before the development of Herceptin, a targeted drug to treat it, this kind of cancer was very dangerous indeed.

TDM1 is the next generation of Herceptin that, in addition to clogging up the HER2 receptors like this video describes, also delivers a miniscule but deadly, targeted dose of maytansine, a poison derived from the maytans tree.

    Thank you for the video. It was fascinating to learn about Her2Positive BC, and add it to my knowledge base of Breast Cancer. It's an epidemic, and we must stop it.
    You're sharing your journey with a group touched as well with a BC experience, or a family member, or someone close.

    I find you to be a remarkable, bright, interesting lady, who walks with God (whatever anyone's "flavor") and I pray and hope you'll get through this God awful challenge. If anyone can, it's you. You're a terrific lady, and God isn't through with your gifts on earth. Give your husband a hug from me. He picked well.

    I don't know why things happen to people, but my family wishes you and your family all the best with love and peace.
    We have never met, but your faith and love of freedom has inspired my family to be loud and proud against round the clock tracking. We are active in trying to reach out to all people and those in influential positions telling them why it is wrong to take those surveillance steps. Thank you Katherine and those who you work with.

    Has anyone found anything like this for endometrial cancer? I have looked up some clinical trials in the US but I don't think I have come across something like this. Any names or links would be appreciated.
