Melanoma is a type of cancer that develops from the pigment-containing cells known as melanocytes. This typically occurs in the skin but may rarely occur in the intestines, mouth, or eye. Some symptoms may be tenderness, pain or itchiness, sores that do not heal, and changes in texture or bleeding from an existing mole.

Leukemia is a cancer of the blood or bone marrow. Bone marrow produces blood cells. Leukemia can happen when there is a problem with the production of blood cells. It usually affects the leukocytes or white blood cells. Some signs and symptoms of this condition may be losing weight without trying, easy bleeding/bruising, recurrent nosebleeds, or tiny red spots on your skin.

AIDS-related Kaposi’s sarcoma is caused by a herpes virus. It may spread through sexual contact. Tumors with tiny new blood vessels grow below the surface of the skin and in membranes of your nose, mouth, eyes, and anus. It can spread to your lungs, stomach, and lymph nodes which are glands that help you fight infection.

Condylomata acuminata is one ofthe most common types of sexually transmitted infections. It affects the moisttissues of the genital area. It may look like small, flesh-colored bumps orhave a cauliflower-like appearance. The signs and symptoms may include itchingor discomfort in your genital area, flesh-colored or gray swellings in yourgenital area, and bleeding with intercourse.

Chronic hepatitis B and C areboth viral infections that attack the liver and they have similar symptoms. Thesesymptoms can include fever, fatigue, dark yellow urine, nausea, vomiting, orpale/gray stools. The most significant difference between hepatitis B and C isthat people may get hepatitis B from the bodily fluids of an infected person. HepatitisC usually spreads through blood-to-blood contact.

Peginterferon Alfa-2b is the same as a protein that your body naturally produces. It is called interferon.

How does Peginterferon Alfa-2b work?

Interferons are a family of small protein molecules that are produced naturally by cells in response to viral infections. Three major classes of Interferons have been identified; alpha, beta, and gamma. Peginterferon Alfa-2b is thought to boost the immune system causing it to attack infected or abnormal cells. This prevents malignant cells from increasing in numbers. In chronic hepatitis B and C, this drug helps prevent these viruses from multiplying in the liver cells.
