Effectiveness

How Fulvestrant Affects PatientsFulvestrant is a type of medicine given by injection that blocks the action of the hormone estrogen. It does not have any known effects that imitate estrogen.
How Fulvestrant works in the bodyFulvestrant is used to treat estrogen-sensitive breast cancer. It works by blocking the estrogen receptors in cancer cells. This prevents estrogen from binding to these receptors, and also causes them to break down. This helps stop the growth of cancers that are resistant to tamoxifen, as well as those that are sensitive to estrogen.

Fulvestrant for Metastatic Breast Cancer Progression Post-Antiestrogen Therapy
So far, I've had two rounds of injections with only minor side effects like insomnia and a sore throat. Fingers crossed that this continues to be an effective treatment for me with no major complications.

Fulvestrant for Metastatic Breast Cancer Progression Post-Antiestrogen Therapy
I am currently on my sixth cycle of this protocol (Fluvestrant with Taselisib) and, so far, it is working well. My doctors tell me that the cancer is 'stable,' which is good news. I am hopeful that the tumors will disappear completely soon. In the meantime, I have learned to relax during treatment and Visualize the tumors disappearing, which has helped reduce the pain significantly.

Fulvestrant for Metastatic Breast Cancer Progression Post-Antiestrogen Therapy
I've been taking this for a couple years now. It's less painful if you heat it up first and administer it slowly. Over time, it became less painful for me in general. Additionally, it halted the growth of my tumor and helped me feel overall healthier--I'm really glad I use this treatment! That said, I do wish it came in pill form.
