Cancer  is a class of diseases in which a group of cells display uncontrolled growth invasion -intrusion on and destruction of adjacent tissues and sometimes metastasis ie spread to other locations in the body via lymph or blood. These three malignant properties of cancers differentiate them from benign tumors, which are self-limited, and do not invade or metastasize. Most cancers form a tumor but some, like leukemia, do not.
Cancer affects people at all ages with the risk for most types increasing with age, Cancer caused about 13% of all human deaths in 2007  ie 7.6 million.

Cancers are caused by changes in the genetic material of cells. These abnormalities may be due to the effects of carcinogens, such as tobacco smoke, radiation, chemicals, or infectious agents. Other cancer-promoting genetic abnormalities may randomly occur through errors in DNA replication, or are inherited, and thus present in all cells from birth. The heritability of cancers is usually affected by complex interactions between carcinogens and the host\'s genome.

Definitive  diagnosis of cancer requires the histologic examination of a biopsy specimen, usually following the initial suspicion of  of malignancy on radiographic imaging. Most cancers can be treated and some cured, depending on the specific type, location, and stage. Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy. As research develops, treatments are becoming more specific for different varieties of cancer. There has been significant progress in the development of targeted therapy drugs that act specifically on detectable molecular abnormalities in certain tumors, and which minimize damage to normal cells. The prognosis of cancer patients is most influenced by the type of cancer, as well as the stage, or extent of the disease. In addition, histologic grading and the presence of specific molecular markers can also be useful in establishing prognosis, as well as in determining individual treatments.


Signs and symptoms

Symptoms of cancer metastasis depend on the location of the tumor.

Roughly, cancer symptoms can be divided into three groups:

    * Local symptoms: unusual lumps or swelling (tumor), haemorrhage (bleeding), pain and/or ulceration. Compression of surrounding tissues may cause symptoms such as jaundice (yellowing the eyes and skin).

    * Symptoms of metastasis (spreading): enlarged lymph nodes, cough and hemoptysis, hepatomegaly (enlarged liver), bone pain, fracture of affected bones and neurological symptoms. Although advanced cancer may cause pain, it is often not the first symptom.

    * Systemic symptoms: weight loss, poor appetite, fatigue and cachexia (wasting), excessive sweating (night sweats), anaemia and specific  conditions that are due to an active cancer, such as thrombosis or hormonal changes.

Every symptom in the above list can be caused by a variety of conditions .Cancer may be a common or uncommon cause of each symptom.


There is an emphasis on early detection of cancer because there is a greater chance of cure and so if you think you may have cancer contact your licensed medical practitioner immediately.
