What is Liver Cancer?

Located between the chest and the abdomen, liver is the largest organ of the body. It is one of the most significant organs of the body without which no one can survive. Therefore, before discussing about the Liver Cancer, let’s have brief discussion about liver.

Shaped like pyramid, liver is the organ with the two lobes (right lobe and left lobe). This is the only organ that receives blood from two sources; blood received from the hepatic artery is rich in oxygen and the blood received from the portal vein is nutrient-rich blood.

Liver Cancer

So, liver has very significant roles to play:

  • Provides energy by transforming sugar and fat into energy
  • It produces bile that helps to dissolve fat and food gets easily digested
  • It produces proteins and chemicals required for the body
  • It stores nutrients
  • At the time of injury, it helps in blood clotting
  • It breaks down some substances such as alcohol and drugs; likewise, waste products get rid of

Besides, it has unique feature that is – it can function even in a condition when small part of it is working. It can repair itself very fast. However, the cancer in liver is such kind of problem that not only damages it, but also takes patient’s life if proper treatment is not given on time.

Liver Cancer: The cancer (basically tumour) when develops in the liver, it is known as liver cancer. Liver cancer is a fatal disease; if it is not diagnosed and treated on time, then it can damage major functioning of the body and finally takes life.

Basically, liver cancer is categorized as:

  • Primary Liver Cancer
  • Secondary Liver Cancer

Primary Liver Cancer:

When the cancer (tumor) starts in the liver and remains in the nascent stage, it is known as primary liver cancer. It is of following type:

  • Cholangiocarcinoma: It originates in the bile ducts and also known as bile duct cancer.
  • Hepatocellular Carcinoma (HCC): It originates in hepatocytes (Liver cell) and also known as hepatoma. This is the most common one.
  • Angiosarcoma: It originates in the blood vessels. It is the rarest type of liver cancer that normally seen in the patients who are aged above 70.

Causes and Risk Factors of Primary Liver Cancer:
