HCC is Hepatic (Liver) Cellular Carcinoma. In my husbands case, he was given Hepatitis C by Army vaccines in 1969. when they were using unsterillized needles repeatedly and air gun injections without changing the vials before deployment. Like AIDS it can hide in the body for 30 yrs. Diagnosed in 1992 but no cure available. Interferon was offered but everyone we know who took it died. Given Harvoni "cure" in 2016 but no mention that Harvoni can double your risk for liver cancer and no annual scans ever suggested. While we were moving in 2021 he experienced severe back pain. CT and MRI showed State 4 HCC with primary large 17cm liver tumor and two smaller 6cm tumors invading the spine at L1 and T8 that had fractured both vertebrae. HCC can also be caused by alcohol but my husband could not drink because of the Hepatitis C, so we know the Harvoni poisoned him. Hep C also caused Hepatic Encephalopathy which is when the damaged or infected liver cannot purge ammonia from bacteria breaking down protein which normally exits via urination so the ammonia stays in the blood and burns the brain causing edema (swelling of brain tissues) and extreme headaches which he suffered with for 30 years. Many Vietnam Era Vets have these issues and don't know what is happening to them. They experience memory loss, confusion, behave inappropriately due to the acid from ammonia in their blood burning their brains and ruining their cognitive functions. They don't know why they are psychotic. We had to go to an outside lab to prove he had Hepatic Encephalopathy because the VA was doing the blood ammonia tests wrong. We were able to get the ammonia down to normal levels by severely limiting meat consumption and using L-Arginine and L-Orthinine which is used in Europe. All the U.S. offers is Lactulose which causes diarrhea to pull ammonia out. Now we just have to beat the HCC which the VA says is incurable. Thank you for the prayers and good wishes it keeps us going thru this long nightmare. Thousands of Vets have died from this syndrome, committed suicide or are still suffering with Hepatic Encephalopathy and worse. The VA advertises go get checked for Hep C because it might be hurting your liver, but they do not mention in the ads. it could also be ruining your brain. They also say if you were born between this year and that year on the ads you should be tested for Hep C tests because they don't want to admit it was the vaccines. 64% of Vietnam Era Vets have contracted Hep C whereas 10 % to 14% have contracted Hep C during other wars. It would be so helpful if word could get out this is how veterans are really treated. We are paying out of pocket for the treatments that are keeping him alive now.
