I️ started the Harvoni drug in November 2014, the week before Christmas, while in the shower, I️ felt a lump in my left breast, a few days later I️ saw my gynecologist who said he didn’t think it was cancer because my mammogram in April was fine. I️ went for a partial mammogram and a biopsy was taken. A few days later I️ found out it was cancer. I️ them had a MRI to compare both breasts. The results showed another tumor on my right breast. I️ couldn’t feel this one. A biopsy was done and it came back cancer. The tumors were different which was very unusual for me to have them at the same time per the doctors. On January 30th of 2015 I️ underwent bilateral breast surgery. I️ finished the Harvoni drug in February 2015. I️ took the drug for 12 weeks. Breast cancer isn’t in my family. All my mammograms were always normal. I️ was a small breasted woman which made it easy to find the lump in my left breast. I️ honestly believe that Harvoni caused my breast cancer.
This is the first time that I have ever read that Harvoni could possibly be responsible for causing Cancer. I would imagine that someone else would have written in by now. But, I also know that there isnt any data out there as yet about the longterm affects of the cure as well. So I guess anything is possible. Then again, it just may be a coincdence or maybe the stress of living with HepC could have caused the cancer? Sorry that you have had to go through such an scary ordeal. And I sincerely hope that your suspicions are wrong.
I Took Harvoni in April. For 8 weeks .so it's been 7 months. I hope you are wrong about the Harvoni. Causing cancer ... so far I have had no side effects. And feel great .but there's a lot of difference in 7 months and 3 years. ..so if anyone else has experienced this .would you please make our group aware of this. ..prayers going out for everyone in our group. To heal and thrive. Have a wonderful veteran day weekend too .as we pay our respects
I was considered cured from Hep C in December 2015 after finishing a 24 week course of Harvoni.
In August 2016 I was diagnosed with stage 4 metastatic breast cancer. The cancer was not seen on any previous annual mammograms. By the time the cancer Dx was made the cancer had spread to lymph nodes, bone, and lung.
I am not at high risk for breast cancer and it doesn’t run in my family.
I too believe Harvoni caused my very aggressive form of cancer. I may not know within my life time, as the statistics for my type of cancer. I have a 23% chance of surviving past August 2018.
I hope that Harvoni didn’t cause my cancer although I believe it did.
Pray for us all.
