The medical term cancer refers to the disease or condition commonly characterized by the abnormal production of an excessive number of extra-large cells foreign to a body organ. The abnormal cells accumulate to perpetually growing tumors and adversely affect normal functioning of the human. Cancer types are named based on the human body organ in which it primarily inhabits. Typological classification of cancer identifies a distinct type, after it exhibits over 35, 000 cases of world wide citing.

Skin cancer currently has the highest tally number of cases reported presently are said to amount to over 1.2 million in the Unite States alone. Thyroid cancer is the least common with 38,000 cases reported in USA. Colon cancer types closely ranked with rectal cancer, collectively called colorectal cancers, ranges between 10000 and 400 000 reported cases at average since 1994. Kidney cancers are categorized into two distinct types namely: renal pelvis cancer and parenchyma. The most common are renal cancers inhabiting the renal section of the human kidney with over 46,000 cases in USA alone, during a recent tally year.

Bladder cancer types typically affects the component human bladder tissues. The human bladder is a body organ charged with the responsibility to temporarily store urine before it’s released, mostly suffers from carcinomas which is a cancer type beginning from the bladder walls and spreading elsewhere in the bladder. The bladder cancer that forms from flat cells in the human bladder is referred to as squamous carcinoma cancer and is characterized by inflammatory effects in the bladder lining.

Breast cancer is another common but women specific cancer types characterized by reddening inflammation of a woman’s breast, causing chronic swelling and painfully high temperatures restricted to the breast. Breast cancer inhabits the breast lobule (milk producers) and ducts (milk transmitting channels) tissues. Endometrial cancer is another women specific condition occurring at the tissues lining the uterus. A natural human uterus is a hollow organ inside the pelvis and basically a fetus during pregnancy. Given that most endometrial cancer cases are adenocarcinomas, their early stages are characterized by cells producing excess mucus and other thick liquid substances on uterus lining. The US reported 40100 new patients of endometrial cancer types and 7501 of which died in one year.

Finally tough not exclusively, Leukemia is also a common type of cancer inhabiting body tissue responsible for blood cells manufacture like the bone marrow. Cancerous cells induce the perpetual production of too many cells which are then released into the blood stream with grave consequences. Most cancer types classification attempts places Leukemia as a blood cancer because the cancerous adversities ultimately reside in the blood. Leukemia by itself is further categorized into two types namely: lymphoblastic leukemia (affecting the lymphatic system) and chronic leukemia (bloodstream based). The Lymphoblastic type of leukemia is the single most common leukemia in the US, going by recent statistics. There is however some other types of cancerous leukemia mostly cited among children but whose occurrence rate is marginal.
