Cancer is a potentially fatal and very complex disease. There are a number of types of cancer known to mankind. Each type of cancer grows and spreads in a different way. Each type of cancer has different sets of symptoms associated with it. Most common types of cancer fall under four major categories:
Carcinoma is a form of cancer which multiplies rapidly and exists in the epithelial region. In other words, this type of cancer exists and grows in body parts like nose, colon, penis, breasts, prostrate, urinary bladder etc. this category forms about 80% of all cancer cases.
The most common symptoms of this type of cancer are dysphagia and weight loss. Patients may experience pain and appearance of a skin lesion. Other symptoms of such cancer includes blood in the urine, abnormally coloured urine, pain in the back, weight loss, enlargement of one testicle etc. One should look for lumps or growths in body for early detection of cancer in the body. Specific screening tests, x-rays etc are used for detection. Blood and urine tests may also be conducted. Special tests like tumor markers, in the blood, urine, or certain tissues may be conducted.
Sarcomas are the tumors which originate, develop and grow in bone, muscle, cartilage, fibrous tissue or fat. Two common types of sarcoma are Ewing sarcoma and Kaposi’s sarcoma.
Ewing sarcoma usually occurs during puberty when the bone grows rapidly. This form of cancer arises in long bones of the extremities like in thigh bone or the pelvis. It is also known to grow in skull bone or trunk bone. The symptoms of such cancer is pain accompanied with swelling and fever. This is a fast growing tumor and spreads into lungs and other bones. No prevention for this type of cancer is known.
Kaposi’s sarcoma is a malignant tumor. It involves skin of people suffering from AIDS. It develops fast on skin, lungs, gastrointestinal tract and other organs of AIDS infected people. Symptoms include existence of an irregularly shaped, bluish-red macule, bleeding, gastrointestinal lesions, shortness of breath etc.
Leukemia can be defined as cancers of the blood or of organs which form blood. Leukemia causes abnormal production of blood cells. Usually this abnormal production is on white blood cells. The leukemia cells have a different appearance and look different from normal blood cells. Such cells also do not work properly. Leukemia can differ in its severity. In acute leukemia, the abnormal blood cells are not developed enough to perform normally. Such cells cannot fight infections. Symptoms include fever, chills, weakness, frequent infections, loss of appetite and/or weight, swollen or tender liver, spleen and lymph nodes, easy bleeding etc.
Lymphomas is the cancer of the lymphatic system. The lymphatic system is used to distribute nutrients to blood and tissue. It also helps fight bacteria and other foreign invaders from attacking the body. This form of cancer spreads to any part of the body including the liver, bone marrow, and spleen.
