We’re Talking Tamoxifen
Let’s go back to 2003 … after my partial mastectomy and radiation therapy I was considered cancer free. The question on the table was would I be able to stay that way?
I was 36 years old. The pathology from my surgery determined my cancer cells were estrogen receptive (ER+). I hadn’t started menopause which meant I had a good amount of estrogen running throughout my body. I had a choice to make: do nothing or start hormone therapy, another adjuvant therapy, and that meant taking Tamoxifen.
Now Tamoxifen was supposed to be a pretty great drug (the FDA touted its benefits when it approved it back in 1998). I was told it would prevent whatever cancer cells I might have had left in my breast from feeding on the estrogen my body produced. I was told it would reduce my risk of recurrence by around 50%.
I was told that my risk of recurrence within five years was maybe around 10%. Taking Tamoxifen would take that number down to around 5%. I liked the lower number, that’s for sure.
Of course, there were some side effects to consider — mostly menopausal symptoms like hot flashes and vaginal dryness — also some risks: blood clots and endometrial cancer.
My oncologist felt the benefits far outweighed the risks. When asked point blank if she would take it if she were me she said, ‘yes.’
There was one potentially big problem, however, from where she stood. If my husband and I wanted a third biological child she could not ethically prescribe the drug for me because it could cause fetal harm were I to conceive while taking it. If we were done having kids, however, she’d write the script that day.
My husband and I looked at each other and smiled. No, we weren’t done having children. Yes, we wanted a third child. But we agreed immediately that she should write the prescription. See, we knew that God’s plan for our lives was to bless us with a third child, a little girl, whose biological parents in China could not raise her. We knew we’d adopt child number three so taking Tamoxifen was not going to be an issue in that regard.
I started taking Tamoxifen the week after my radiation therapy had ended. I experienced no side effects at all while taking the drug. But there was one big problem. Tamoxifen was supposed to keep me cancer free. Remember the numbers? It was supposed to reduce my risk of recurrence by about 50%. It was supposed to bring my personal risk of recurrence within five years from 10% down to 5%.
The cancer cells in my body didn’t listen to the numbers that day in my oncologist’s office. They had their own plan and it didn’t involve me staying cancer free for long.

Thanks for reading my article about breast cancer vaccines. I have dedicated my profession to study ways to cure breast cancer.
Your posting has touch me same as all postings I read from women with breast cancer. It makes me want to go back to the lab and keep doing my research. If you want you can write me anytime to let me know how you are doing.
Wish you the best!

Dr. Nava-Parada, it is an honor to read your comment!
(I need to post on the vaccine; if you want to read up on what it’s all about before I get there, head over to http://www.eurekalert.org/pub_releases/2007-04/mc-bcv041207.php)
Keep up the good work — your research makes a huge difference in our lives.
