Liver Cancer – Causes, Symptoms and Treatment



The liver is the largest internal organ in the body. It is also known as primary liver cancer or hepatoma and hepatocellular carcinoma is a cancer arising from the liver. The liver performs several vital functions. It processes and stores many of the nutrients absorbed from the intestine. It also makes some of the clotting factors needed to stop bleeding from a cut or injury. Hemangioma (he-man-ge-O-muh) is the most common type of benign liver tumor. It starts in blood vessels and Hepatic adenomas are benign tumors that start from the main type of liver cells (hepatocytes). Women have a much higher chance of having one of these tumors if they take birth control pills, although this is rare. Stopping the pills can cause the tumor to shrink. Hepatic adenomascancer begins in many spots throughout the liver and is not confined to a single tumor. This is most often seen in people with liver cirrhosis and is the most common pattern seen in the United States.

Hepatic tumors also called Liver cancer. Hepatic tumors is are tumors or growths on or in the liver. There are many forms of liver tumors premary is Malignant. Malignant, primary liver cancer is hepatocellular carcinoma (also named hepatoma, which is a misnomer). These growths can be benign or malignant (cancerous). They may be discovered on medical imaging (even for a different reason than the cancer itself). Most of the time when cancer is found in the liver, it did not start there but spread to the liver from a cancer that began somewhere else in the body. These tumors are named after the place where they began (primary site) and are further described as metastatic. Symptoms can include a lump or pain on the right side of your abdomen and yellowing of the skin. However, you may not have symptoms and the cancer may not be found until it is advanced.

Some researchers believe that cancer starts with damage to DNA the material that contains the instructions for every chemical process in your body, including the rate of cellular growth. DNA damage causes changes in these instructions. Liver cancer also occurs as metastatic cancer, which happens when tumors from other parts of the body spread (metastasize) to the liver. In the liver cancer some cells begin to grow abnormally. One result is that cells may begin to grow out of control and eventually form a tumor a mass of malignant cells. In the United States, most cancer found in the liver spread there after originating elsewhere. Rather than being called liver cancer, this type of cancer in the liver is named after the organ in which it began such as metastatic colon cancer in cancer that starts in the colon and spreads to the liver.

Causes of liver Cancer

Hepatitis B virus (HBV) infection is the main causes of liver cancer. Liver cancer relates to (correlates with) the frequency of chronic hepatitis B virus infection. Studies in animals also have provided that hepatitis B virus can cause liver cancer. For example, liver cancer develops in other mammals that are naturally infected with hepatitis B virus-related viruses. Finally, by infecting transgenic mice with certain parts of the hepatitis B virus, scientists caused liver cancer to develop in mice that do not usually develop liver cancer.

Symptoms of liver cancer
Liver cancer is very common larges countries in world wide. Generally is discovered at a very advanced stage of cancer disease for several reasons. In addition, patients from these regions actually have more aggressive liver cancer disease. live cancer tumor usually reaches an advanced stage and causes symptoms more rapidly. Abdominal pain is the most common symptom of liver cancer and usually signifies a very large tumor or widespread involvement of the liver and other symptom is weight loss. These symptoms are less common in individuals with liver cancer in the U.S.an additionally symptoms is ascites (abdominal fluid and swelling), jaundice (yellow color of the skin), or muscle wasting.

Treatment of liver cancer

The treatment of liver cancer is overall condition of the patient. First treatment if liver cancer is Chemotherapy. Chemotherapy is a powerful drugs to kill cancer cells. Chemotherapy is anot effective not some cases of liver cancer but type of chemotherapy is known as chemoembolization is an important part of treatment for HCC. chemoembolization causes many of the same side effects as other forms of chemotherapy, including abdominal pain, nausea and vomiting. Second treatment is surgery. Surgery is best treatment for localized resectable cancer is usually an operation known as surgical resection. In some cases, the area of the liver where the cancer is found can be completely removed. Alcohol injection has been shown to improve survival in people with small hepatocellular tumors. It may also be used to help reduce symptoms in cases of metastatic liver cancer. The most common side effect is leaking of alcohol onto the liver or into the abdominal cavity.

Toads and Warts



It was a popular myth in the old days that you can get warts from toads. Not true – now we know that’s bogus. Warts are actually benign tumors of the epidermis caused by a virus. The virus responsible is the human papillomavirus, a double-stranded DNA-virus. The virus resides in the bottom layer of the epidermis and replicates into almost normal-looking skin. Different sub-types of the human papillamavirus cause different types of warts. Some subtypes also cause cervical cancer and other more obscure types of wart-related cancers.

Another myth about warts is that they have “roots” but warts do not have “roots”. They only grow in the top layer of skin, the epidermis. When they grow down, they displace the second layer of skin, the dermis. The underside of a wart is actually smooth. Warts are caused by a virus that enters the body through a break in the skin. The virus grows in warm, moist environments, such as those created in a locker room or in your shoes when your feet perspire and the moisture is trapped.

Warts normally grow out of the skin in cylindrical columns and they do not fuse when the wart grows on thin skin such as the face. On thicker skin, the columns fuse and are packed tightly together giving the surface the typical mosaic pattern. Dark dots can sometimes be seen in a wart and it is actually blood vessels that have grown rapidly and irregularly into the wart and have thombosed or clotted off.

Warts can occur in people of all ages, but hit most often children and young adults. They spread by direct contact, simply by touching the wart. Most warts resolve within weeks or months, some may take years. Although that is unusual and persons prefer to treat the warts very quick. It appears that a person’s susceptibility to warts and the time it takes for them to go away is related to the individual’s immune system. People who have immune-related diseases tend to have more warts that last longer.

What kind of treatment is there?

Most warts can be treated with simple over-the-counter remedies. For those that are resistant to these measures, there are other types of treatments that are effective. In your local drug store you may find good working remedies. Try it and if it works, great. If it does not work you lost a few days and some dollars. Then you will perhaps search for a professional opinion from a doctor and they will probably recommend you some of the following treatments.

Salicylic acid is very common and an effective over-the-counter treatment. You have to do a consistent application every day. The best way to use salicylic acid is to first pare the wart with a blade, pumice stone or a small scrub brush. Soaking the wart in warm water will aid to get a better absorption of the medicine. Salicylic acid is then applied to the wart and allowed to dry. Occluding the treated wart with a band-aid or piece of tape also improves the absorption of the medicine. This procedure should be repeated daily.

If the wart is resistant to your treatment, your physician may recommend an office procedure to remove it. After a local anesthetic is applied, the physician may use liquid nitrogen to freeze the wart and dissolve it. To avoid scarring or damaging other tissues, this method removes only the top portion of the wart. The treatment must be repeated regularly until the entire wart is dissolved. Alternatively, the physician can cut out the wart.

The human papillomavirus is not killed by cryotherapy and is released into the surrounding tissue. The immune system will usually take care of the virus. You will have a blister as a side-effect of the treatment. Nothing to think about unless you have the warts on the bottom of the foot. Then you should perhaps choose another treatment.

Some warts will go away, your immune system take care of them. If not, you will have a number of treatments available that will most certainly work well.

A Brief Description of Pleomorphic Adenoma



The most common kind of the benign tumor is the pleomorphic adenoma in the salivary glands which is also called the mixed tumor as the tissues are originated from various types of cells. Looking at the tumor’s physical appearance, it appears to be a hard and a painless mass that usually grows gradually over time.

It mostly develops in the parotid gland with very rare instances of occurrence in the submandibular glands or in the minor salivary glands. Though salivary glands are the glands from where the saliva are produced but the parotid gland is regarded as the largest salivary gland that is found near the upper teeth and the just beneath the ear. It is generally found to occur in the people of age group 45 – 60 years and is mostly detected in females than in males. One can associate factors like chain smoking and radiation exposure with the pleomorphic adenoma, but usually it happens because of the blockage of the salivary ducts. If left untreated, the tumor can become malignant where the cancerous tumor is called the malignant mixed tumor or the carcinoma ex pleomorphic adenoma.

Generally a fine needle aspiration (FNA) is used to diagnose the presence of the pleomorphic adenoma, and CT (computer tomography) scans and the MRI (magnetic resonance imaging) tests are also conducted to examine its place and size. The surgical resection is the common treatment done to remove the pleomorphic adenoma or the organ that is affected by it, but good care is to be taken while performing the surgery as it can also cause the damage of the facial nerves. The complete removal of the adenoma tumor is done with scalpel for the benign tumors in the salivary glands.
