I finished 234 weeks of Harvoni and was considered cured December 2015.
By August 2016 I was diagnosed with stage 4 breast cancer. I had a mammogram in 2015 and all of a sudden I have stage four cancer with prognosis of two years to live. Has anyone else developed aggressive form of cancer after finishing Harvoni treatment? I believe this is not unusual and the drug manufacturer is hiding this information.
Added 31 July 2017:
I finished 24 weeks of Harvoni treatment, not 234 weeks! Sorry, my mistake

Five years ago I did 12 weeks of Harvoni, cured my Hep C. Within a year and a half I was diagnosed with Stage 4 Metastatic Prostrate cancer. I was not sick at all with Hep C, numbers were low, but Dr said try this new drug, it was 12 weeks of hell!! Then Dr retired!!

My 57 year old daughter, took 12 weeks of Harvoni treatment for Hep C in 2014, 2015- after treatment she was clear of Hep C. During treatment the medicine made her very weak, nauseated and much joint pain. By 2018 she was very sick with respiratory problems, that antibiotics could not cure. By May of 2019 she was so weak and sick she moved home from South Texas to Missouri with us, her parents. Right away we were making trips to the emergency room with her and being seen at walk in clinics almost daily. In late June if 2019, while being exrayed for possible blocked bowel, they saw holes in her hip and pelvis bones. She was referred to Siteman Cancer Center in St Louis, the diagnosis was a rapid cancer that had metastasized to the lungs, throat, spine hips pelvis, her body was ravaged with cancer. The cancer grew so rapid she was dead by July 28, 2019. Could Harvoni have been the cause, our family does not have a history of cancer.

My brother was 58 started Harvoni in May of 2017 completed dosage mid June. He was diagnosed with two separate cancers the end of June 2017 he was now 59 he had bladder cancer and liver cancer two separate cancers. He died August 10 2017. No doubt in my mind Harvon contributed to my brothers death.

Yes I was fine altough I had hep C but no symptoms. Felt great Harvoni came out and my dr.said let's do this " since this miracle drug came out. So I did and cured the hepC but before he released me for once a year visits they found a rare cancer and now I have all kinds of problems and trying to get on a transplant list. I don't even think I'll do a transplant if offered. I've so many embolism treatments ro try and slow it down i can't take anymore. Just waiting for a miracle from God is all I have left. Think hard about it. Me personally with all I know now I wouldn't have that drug in my house. Lawsuits are going to run rampant. I'm absolutely sure this drug caused it. I'd still be just fine if I hadn't taken it. Best for you, but pray now.

Were you referring to me earlier. "This Stephen guy is posting all over the place"?
I posted here with the best information available at the time years ago. Just to make you happy, I have recently been diagnosed with an insanely aggressive liver cancer that seems to have developed just 3 months ago and is now Stage 2. I don't have high hopes of making it through the next 6 months, it is already causing intermittent pain. Sleep well buddy and know that your wish has been fulfilled..

Hi Kathie1990 I took Harvoni for 8 weeks around two years ago. I have been having some unexplained pain only upper liver area. I have not been checked for cancer yet, but after reading your post I will get checked as soon as I can. I am so very sorry to hear about all the cancer that has been showing up after taking Harvoni. No one told me of any side effect from taking Harvoni. I am very scared now. May God bless all of you and be there for you to give comfort and strength during your time of need. This is just wrong to give someone a drug to cure them from being sick and it ends up giving you cancer that will take your life.

This concerns me since there is cancer in my family history. 9 days on harvoni treatment and haven’t had a good day yet. I’m so sorry to hear about your situation. I think they rushed it to the public without extensive studies, this is not the only site that I have read this on. My Dr told me it’s a risk/reward kind of thing I’ve read of a few rewards but what happens years after treatment. Drs are pretty mum on the correlation between the too.

I stopped treatment after 28 days as the side effects were not minimal, and included a resurgence of heart and lung problems, as well as severe joint pain. Of course the docs adamantly claimed the side effects were so minimal as to not even be worth concern. They vehemently denied any correlation between Harvoni and cancers, heart and respiratory disease, nor arthritis. I stopped treatment and pray I did not ingest enough Harvoni poison! There are lawyers now taking these cases, hoping it becomes a class action suit.

My Mother died 1.5 years after taking this horrible drug. I feel responsible because I told her about it. Now she is gone and I will have to live with this for the rest of my life. She had HepC for over 30 years with NO cancer and mild cirrhosis. After taking it, she had a cough that wouldn't go away, problems with her ankles and an aggressive form of a 'rare' cancer - biliary cancer - right on the liver where the bile ducts connect to the liver. She was diagnosed in March 2017 and dead within 6 weeks. I pray there is a class action. Get copies of all your medical records for your family just in case something happens.

I was diagnosed on jan31,18 with inflammatory breast cancer my family has no history of breast cancer I took harvoni two and a half years ago, and that's the only thing I did different in the past ten years. I also believe harvoni is the cause of my cancer,it is very aggressive I haven't been given a prognosis yet but my oncologist is just getting started, I was fine before i took harvoni the hep c wasent having any bad effects on me so yes I also regret taking harvoni, and just as I was in a point in my life that being a grandma was wonderful( still is of course) but I won't be here to watch them grow up and becoming a great grandmother won't happen either.
If I knew then what I've learned in the last year+ I never would have taken any of the pills from our own pharmaceutical world, I have learned that our country allows dangerous medications on the market knowing that there pills are dangerous and almost always cause patients other medical problems I believe this is intentionally being done to americans , its all about the money and population control all we Americans are to them is a number.

The mechanism between Harvoni and liver cancer is getting better understood, sadly there is no way to screen for it. I took an unknowing roll of the dice and came up a winner, sorry that your experience was not the same. Liver cancer is the only recognised Harvoni cancer to this date.

I took harvoni for three months ten months later I also have been diagnosed with stage 3 metastatic carcinoma I do believe that the harvoni drug caused my breast cancer
A number of people have reported the appearance of aggressive liver tumours that they put down to the use of Harvoni. Sadly, for many of the older people, the cancers were probably inevitable. This is the first report of other cancers being implicated that I have read of. The real proven answer probably won't be known for years.
Best wishes on your journey.
