The Liver largest internal organ in the body and is located directly below the right lung. The Liver consists of the right lobe and left lobe, which comprises hepatocytes cells responsible for processing the nutrients from the blood. Hepatocytes help break down and store some nutrients and also help remove any waste from the body. The Liver also produces bile fluid that helps us break down drugs, alcohol, and other toxic waste in the blood, then passing from our body through stool and urine. A liver cancer diagnosis is often due to cancer metastasizing from a different area and is therefore known as secondary liver cancer. The different types of cells in the Liver can result in many cancerous (malignant) and noncancerous (benign) tumors. These variations of tumors all have different causes, are must be treated differently.
Global Liver Cancer Statistics
Based on recent statistics from 2019, Liver cancer is the fourth most commonly occurring cancer in men and the eighth-most common cancer type in women. The total number of patients with primary liver cancer has nearly tripled since the 1980s due to liver disease growth due to conditions such as hepatitis C. Primary liver cancer generally tends to be diagnosed in patients in their 50s and 60s and is more frequently found in men.
Types of Liver Cancer
There are many liver cancer variations and each type is quite different in the way it develops and mutates over time. Treatment options also vary depending on the type, scale, and severity of the diagnosis. The three most common types of liver cancer include:
Hepatocellular carcinoma (HCC)
HCC is the most common form of primary liver cancer in the world. This type of cancer starts in the hepatocytes (liver cells), that process nutrients in the blood. HCC Cancer often develops as a single small tumor that spreads (metastasizes) to other organs and tissue in the body. Another type of HCC liver cancer starts as many tiny cancer nodules in the Liver (instead of a single tumor). This type of liver cancer is seen most often seen in patients with chronic hepatic tissue damage and liver cirrhosis. Many patients with hepatocellular carcinoma also have some other disease of the Liver that is causing inflammation and fibrotic scarring in the liver, including:
- Fatty liver disease which can be attibuted to excessive alcohol consumption
- Chronic hepatitis B or C virus
- Metabolic abnormalities, such as hemochromatosis (too much iron in the body) or nonalcoholic fatty liver disease.
Bile duct cancer – Intrahepatic Cholangiocarcinoma
Intrahepatic cholangiocarcinoma (cancer of the Bile ducts), is the second most diagnosed type of primary liver cancer. This type of liver cancer usually starts bile duct cells (tube-like structures) that deliver bile; about 15% to 25% of cases of this type of cancers are intrahepatic cholangiocarcinomas. Many cholangiocarcinomas also start forming in the bile ducts outside the Liver.
Hemangiosarcoma and Angiosarcoma
These rare types of liver cancers usually form on the cell lining of blood vessels inside the Liver. Common causes of Angiosarcoma and Hemangiosarcoma include patients exposed to toxins such as thorium dioxide (Thorotrast) and vinyl chloride. Other known risk factors include environmental exposure to radium or arsenic and can also be diagnosed due to mutations in the DNA resulting in an inherited condition called hereditary hemochromatosis. In more than 40% of cases, the diagnosis is considered idiopathic as no clear link can be identified. 
Tumors from Hemangiosarcoma and Angiosarcoma cancer increase and are often too widespread to be treated surgically by the time they are discovered. In some cases, radiation therapy (Chemotherapy) might help slow the disease, but these methods often fail as these particular types of cancers are challenging to treat.
Fibrolamellar-Hepatocellular Carcinoma (FLL-HCC)
Also called fibrolamellar carcinoma, this type of hepatocellular carcinoma is quite rare and is considered less aggressive than other known liver cancer types. FLL-HCC usually develops in young adults and is often misdiagnosed as a type of focal nodular hyperplasia, a noncancerous liver tumor.
This rare type of primary liver tumor usually develops in children less than five years old. When seen under a microscope, the hepatoblastoma cells look very similar to fetal liver cells comprised of tissue that resembles bile duct cells, fetal liver cells, or mature liver cells. Hepatoblastomas is curable with chemotherapy or surgery, but the tumors become much harder to treat if they spread outside the Liver.
Metastatic liver cancer – Secondary liver cancer
When liver cancer is found, it did not develop there but has metastasized (spread) from other organs in the body, including the colon, lung, pancreas cancer, stomach, prostate cancer or breast cancer. Since this type of cancer has spread from another (primary) site, it is referred to as secondary liver cancer. These naming and treatment options for the tumors are based on the original primary site where it started. For example, cancer that started in the pancreas and spread to the Liver is called Pancreatic cancer, and not liver cancer. It is also treated like pancreatic cancer. In Europe and North America, secondary (metastatic) liver tumors are more commonly diagnosed than primary liver cancer, but the opposite is true for many parts of Asia (Thailand) and Africa.
Benign Liver Tumors
Sometimes, the tumors found in the Liver are classified as noncancerous (benign). This type of cancer usually doesn’t cause any severe symptoms or discomfort. Benign liver tumors are often found by chance when a patient undergoes imaging tests for other health conditions. Common benign tumors in the Liver include:
- Cysts in the Liver
- Focal nodular hyperplasias
4 Stages of Liver Cancer
When a patient is clinically diagnosed with liver cancer, oncologists will first try to determine if the cancer tumors have spread, and if so, how far. This diagnosis process is called staging. The stages of cancer describe how severe the cancer is in the body. Staging helps doctors determine how severe the cancer is and what the best treatment option is. Oncologists also use a patient’s cancer stage to discuss realistic survival chances.
Stages for liver cancer can range from stage I (1) through IV (4). Generally speaking, the lower the stage number, the less cancer has spread. A higher stage (stage 4) means the liver cancer has spread more. Each patient’s cancer experience is unique, but cancers with similar stages generally have similar outlooks and are typically treated the same way. The staging systems vary around the world, but the most common systems include:
- AJCC (American Joint Committee on Cancer)
- The Okuda System
- Child-Pugh score
- The Cancer of the Liver -CLIP Italy
- The Barcelona Clinic Liver Cancer (BCLC) system
These different types of staging systems are usually not compared against each other, and usage depends alot on which part of the world you reside in. At this time, there is no universal staging system that all doctors in the world use.
Classifications of Liver cancer
Staging systems can often help oncologists determine outlook. Still, for treatment purposes, some doctors classify liver cancers much more simply, depending on whether they can be surgically cut out (resected). Resectable cancer means that the tumor can be removed via surgery (partial hepatectomy.) Other types of simple classifications include:
Unresectable liver cancer: Cancers that have not yet spread distant organs or lymph nodes but can’t be removed entirely via means of surgery are classified as unresectable cancers. These types of liver cancers include those that have spread through the entire liver organ or cannot be safely extracted due to proximity to sensitive areas around the Liver, including the veins, main arteries, or bile ducts.
Transplantable liver cancer (Potentially resectable) – If patients are healthy enough for surgical intervention, liver cancer can be removed entirely by either surgery or treated using immunotherapy or total liver transplant. This generally is an option for patients in stage 1 and some stage 2 cancers but requires that patients do not have liver cirrhosis or any other severe medical conditions. A minimal number of patients diagnosed with liver cancer have these types of tumors.
Inoperable liver cancer: If the liver cancer is small enough, in a safe place to be removed, but a patient is not healthy enough to have surgery, it will be classified as Inoperable. This usually occurs because a noncancerous part of the Liver might not be healthy enough (due to cirrhosis etc.). If the cancer is removed surgically, there might not be enough healthy liver tissue remaining for a properly functioning liver. This classification is also reached if a patient has comorbidities that would make surgery dangerous.
Advanced (metastatic) liver cancer: Cancers that have already spread to the lymph nodes or other organs in the body are classified as advanced. Most advanced liver cancers cannot be treated with surgery alone.
Symptoms of Liver Cancer
Common Symptoms associated with HCC & Liver Cancer include:
- Loss of appetite
- Pain in the right shoulder
- Feeling of weakness
- Weight Loss
- Abdomen pain/discomfort or swelling
- Elevated liver enzymes found on Liver Function Test
Liver Cancer Prevention & Risk Factors
Major Risk Factors associated with cancer in the Liver include:
- History of Liver Cirrhosis
- Reaction to foods containing aflatoxins, a family of toxins produced by some fungi (commonly found on maize, tree nuts, corn, peanuts, and cottonseed
- Smoking tobacco
- Alcohol abuse
- History of Diabetes
- History with the hepatitis B and C Virus
- Men have a greater risk of developing liver cancer than women
- The average age patients develop liver cancer is about 55
- Exposure to environmental toxins
Hepatitis B or C infections or drinking too much alcohol are often contributors to scarring of the Liver. Asymptomatic viral infections from HBV cause more than 75 percent of primary liver cancers worldwide. Primary liver cancer caused by viral infections and hepatitis develops slowly over decades and often goes undetected. Preventative medical screening for infections helps prevent them from becoming advanced and causing cancer. Chronic systemic infections of Hepatitis C virus (HCV) and Hepatitis B virus (HBV)are major risk factors for developing liver cancer.
Diagnostic Tests for detection of Cancer in the Liver
Several types of medical tests can be done to detect or eliminate the possibility of liver cancer tumors. Standard diagnostic tests include:
- Physical examination with a general physician or gastroenterologist to get information about your medical history to determine overall risk factors for developing liver cancer. Physical exams of the abdomen area, skin, and eyes (signs of jaundice). Depending on the initial physical exam findings, further tests may be required to determine the cause of symptoms.
- Radiology tests & Imaging– As the name implies, Imaging results provide clear visual scans of internal body parts using x-rays, magnetic fields (MRI), or sound waves (Ultrasound.) CT scans, bone scans, and angiography are some other standard tests done to evaluate liver cancer.
- Laparoscopy procedures use a thin tube with a camera inserted through the abdomen to better see the liver tissue and surrounding organs. Diagnostic laparoscopy is a low-risk, minimally invasive surgical procedure that requires micro incisions. A Laparoscopy can be performed to better determine the current stage of liver cancer, help create a customized stem cell treatment plan, or confirm an existing diagnosis.
- Liver Biopsy is a surgical procedure that can help detect cancer cells’ presence through a sample of patient liver tissue.
- Lab tests & Blood panels are very inexpensive and effective means to determine if the body and internal organs are functioning correctly, track treatment progress, search for cancer markers or detect for recurrence of cancer
- Genetic screening for Cancer – ctDNA (Circulating tumor DNA) analysis differs from traditional diagnostic tests that were available. Unlike invasive tissue biopsies, Cancer biomarker assessments like the ctDNA Analysis requires simple saliva samples or cheek swabs. Rapid screening is a prognostic marker detection, consistently predictive. It can provide a very early assessment of potential metastatic disease, treatment monitoring, and determination of epigenetic and genetic alterations from primary cancers.
Immunotherapy Liver Cancer Treatment in 2022
Available Treatments for HCC and Liver Cancer
Most patients diagnosed with liver cancers are treated with combinations of radiation therapy, chemotherapy, or surgery. Radiation based therapies are disadvantageous as the high-energy particle rays do not target the cancer cells and destroy healthy cells causing severe side effects. The levels of radiation exposure in chemotherapeutic doses must be limited to avoid organ toxicity. Therefore, the 21st Century approach requires more precisely targeted therapies that are capable of killing cancer cells while ignoring the healthy cells. The combination of modern immunological cancer therapies and stem cells is much more targeted and significantly less toxic while maintaining similar and often better results depending on the type, age, and diagnosis stage. Immune boosting therapies are also more effective in achieving long-term tumor immunosurveillance while reducing the chance of relapse.
Its time to change how the world treats cancer
Immunological therapies can increase long-term disease-free survival and are prescribed as adjuvant therapy for patients with low white blood cell counts. Stem cell therapy for liver cancer helps boost a patient immune system with a naturally produced growth factor to enhance the cancer-fighting capacity.
Immunotherapy for liver cancer is quickly becoming a standard-of-care treatment and, in some cases, a complete cure. Immunotherapies refers to manipulating or mobilizing the patient’s immune system to treat or cure liver cancer. Immunological therapies can also be performed via manipulation of genes using NK Cells, Dendritic cells (DCs), Monoclonal antibodies therapy, Immune modulators, adoptive cell transfer, an oncolytic virus therapy, which is a virus-based delivery system of modified genes where the payload uses the viruses as a host to carry past the patient’s immune system.
Immunotherapy for liver cancer
Patients diagnosed with HCC who initially might have responded well to medications that target PD-1 protein (checkpoint inhibitors) can, over a short time, develop resistance to these therapies, significantly if cancer has metastasized from its primary location to spawn additional liver tumors. In such cases, genes encoded with tumor-associated antigens (TAA) induces a much for an adequate response from the immune system.
Earlier clinical trials on liver cancer focused on identifying the proliferating progenitor cells (CD34+) in human blood. These progenitor cells are stimulated by cytokines (GM-CSF and TNF-alpha) to differentiate into dendritic cells rapidly. For some cases, using a combination of IL-4 & GM-CSF helps to generate significantly larger quantities of cancer-fighting dendritic cells from monocytes and macrophages.
Immunological therapy for liver cancer might soon be the gold standard in the treatment of liver tumors for these reasons:
- Targeted Liver cancer immunotherapy can target and debulk the tumor mass at the same time kill the tumor via inducing a normal cellular response and paracrine cell signaling
- Immunological therapies help save a copy of the memory responses (immunosurveillance). This significantly reduced the risk of relapses.
- The combination of stem cells and immunotherapy growth factors help to reduce nearby lesions and prevents metastases from forming on the cellular level, thus improving cytoreduction while avoiding the destruction of normal healthy cells
- Liver Cancer stem cells therapies are non-toxic and may not require the use of chemotherapy and its adverse side effects
- Recent data indicate that adoptive T cell therapy is successful in the treatment of liver cancer. This breakthrough therapy for HCC is essential as without having the treatment, the estimated five-year survival rate is just below 5%.
TREATMENT PRECAUTIONS & RISKSPlease note cellular and immune system therapies are not appropriate for all types of cancer. Risk is a part of any medical treatment. Though scientific based regenerative technologies have made liver cancer treatments safer and a more reliable treatment option, there is always the potential risk of problems and or side effects.

Warning and Dangers of Herbal Therapies
Some herbal based treatment might help treat some symptoms associated with liver cancer, but patients diagnosed with cancer need to be extra precautious before digesting an herbal remedy. A compromised liver may have a much harder time breaking down or metabolizing” substances. In particular, patients with lung cancer have a challenging time processing alcohol. Since many herbal preparations and extracts are alcohol-based, liver cancer patients should always double-check all the ingredients before taking any herbs. Furthermore, some herbal supplements for liver cancer can cause excessive bleeding and prevent blood from clotting properly.
