fatty liver

Fatty liver is just what its name suggests: the build-up of fat in the liver cells. Although this is not a normal condition, fat in the liver usually causes no damage by itself. However, on some occasions it can be a sign that other more harmful conditions are at work. Fatty liver may be associated with or may lead to inflammation of the liver. This can cause scarring and hardening of the liver. When scarring becomes extensive, it is called cirrhosis, and this is a very serious condition. Therefore, it is important that a physician thoroughly examine a patient with fat in the liver.

The term hepatitis means inflammation of and damage to the liver cells. Steato (pronounced stee-at´-toe) refers to fat. Therefore, steatohepatitis is inflammation of the liver related to fat accumulation. Heavy alcohol use can lead to fatty liver and inflammation, usually called alcoholic hepatitis. Steatohepatitis resembles alcoholic hepatitis, but it can and does occur in people who seldom or never drink alcohol. In this instance, it is often called nonalcoholic steatohepatitis or NASH. Both alcoholic hepatitis and steatohepatitis can lead to serious liver damage and cirrhosis. Studies have shown that many people who are significantly overweight have developed, or will develop, steatohepatitis. It can also occur with rapid weight loss. Steatohepatitis has been connected to estrogen hormones in some women. In the case of diabetes mellitus, researchers believe steatohepatitis may develop only in those patients whose diabetes is not properly controlled.

In most instances, treatment of fatty liver and steatohepatitis requires control of the underlying conditions. This may include reduction of high blood triglycerides, good control of diabetes, or not drinking alcohol. In some cases, surgical reversal of intestinal bypass for obesity is required. Since being overweight is by far the most critical factor, weight loss is the key to ridding the liver of fat. This is especially necessary if damage to the liver is occurring, and early signs of scarring are present on biopsy. High blood triglycerides and diabetes are also worse with obesity. So, when steatohepatitis is present with these conditions, people gain even greater benefits from losing weight. Losing weight can be difficult. However, it must be done because the alternative may be eventual cirrhosis and the need for a liver transplant. Currently, studies are underway on certain drugs such as Actigall. This drug appears to reduce liver damage in cases of steatohepatitis. At this time, however, it is not certain how helpful these drugs will be. To repeat the point, losing weight is by far the most important treatment.

Cancer liver II

Definition of liver cancer: Primary liver cancer is cancer that forms in the tissues of the liver. Secondary liver cancer is cancer that spreads to the liver from another part of the body.

Estimated new cases and deaths from liver and intrahepatic bile ductcancer in the United States in 2009:

	New cases: 22,620
	Deaths: 18,160

This booklet is only about cancer that begins in the liver. It isn't about cancer that spreads to the liver from somewhere else.

It's common for cancer to spread (metastasize) to the liver from the colon, lungs, breasts, or other parts of the body. When this happens, the disease is not liver cancer. Instead, the cancer in the liver is named for the organ or the tissue in which it began. For example, colon cancer that spreads to the liver is metastatic colon cancer. It is not liver cancer.

In the United States, metastatic cancer in the liver is far more common than primary liver cancer.

People with metastatic cancer in the liver have different treatment options than those with primary liver cancer.

Cancer begins in cells, the building blocks that make up tissues. Tissues make up the organs of the body.

Normal cells grow and divide to form new cells as the body needs them. When normal cells grow old or get damaged, they die, and new cells take their place.

Sometimes, this process goes wrong. New cells form when the body doesn't need them, and old or damaged cells don't die as they should. The buildup of extra cells often forms a mass of tissue called a growth, nodule, or tumor.

Growths in the liver can be benign (not cancer) or malignant (cancer). Benign tumors are not as harmful as malignant tumors:

Benign tumors:

• • are rarely a threat to life
  • can be removed and usually don't grow back
  • don't invade the tissues around them
  • don't spread to other parts of the body
  
  
• Malignant growths:
  • may be a threat to life
  • sometimes can be removed but can grow back
  • can invade and damage nearby tissues and organs (such as the stomach or intestine)
  • can spread to other parts of the body

Most primary liver cancers begin in hepatocytes (liver cells). This type of cancer is called hepatocellular carcinoma or malignant hepatoma.

Liver cancer cells can spread by breaking away from the original tumor. They mainly spread by entering blood vessels, but liver cancer cells can also be found in lymph nodes. The cancer cells may attach to other tissues and grow to form new tumors that may damage those tissues.

The liver

An organ in the upper abdomen that aids in digestion and removes waste products and worn-out cells from the blood.

The liver is the largest solid organ in the body.

The liver weighs about three and a half pounds (1.6 kilograms).

It measures about 8 inches (20 cm) horizontally (across) and 6.5 inches (17 cm) vertically (down) and is 4.5 inches (12 cm) thick. . .
