Types of Cancer

Cancer is an uncontrolled growth of a group of cells, invading the adjacent tissues or spreading to far off places in the body, through lymph or blood. Cancer still does not have definite cure as yet. Cancer affects people of all ages, even the fetuses in a womb. However, the risk of developing cancer increases with old age. Except for leukemia, almost all the types of cancer result in the development of a tumor.
Following are various Types of Cancer:
1.       Lung Cancer: It is caused by an uncontrolled cell growth in lung tissues. The growth, though it occurs in the lungs, leads to metastasis, which causes penetration beyond the lungs.
2.       Breast Cancer: Breast cancer starts in the cells of the breast of an individual. Though women are generally more prone to this type of cancer, men are no exception.
3.      Prostate Cancer: This type of cancer affects only the males. It develops in the prostrate, a gland in the male reproductive system, and may spread to other parts of the body, especially the bones and lymph nodes.
4.      Bladder Cancer: In this type of cancer, abnormal cells multiply, without control, in the bladder. Several types of growth might occur in the urinary bladder, in bladder cancer.
5.      Pancreatic Cancer: A tumor of the pancreas, this cancer causes pain in the upper abdomen, along with loss of appetite, significant weight loss and painless jaundice.
6.Leukemia: Leukemia is a type of cancer that affects the blood or bone marrow of a person. In leukemia, there is a multiplication of white blood cells.
7.      Ovarian Cancer: Exclusively found in women, ovarian cancer is the fifth leading cause of cancer-related deaths in women. In this type of cancer, a growth forms in the lining of the ovary or in the egg cells.
8.      Colon Cancer: Colorectal cancer, also called colon cancer or large bowel cancer or "CRC", includes cancerous growths in the colon, rectum and appendix.
9.      Hodgkin’s disease: Hodgkin's lymphoma, previously known as Hodgkin's disease, is a type of lymphoma, which is a cancer originating from white blood cells called lymphocytes. It was named after Thomas Hodgkin, who first described abnormalities in the lymph system in 1832.
10.   Multiple Myeloma: Multiple myeloma is cancer of the plasma cells in bone marrow.
11.    Skin Cancer: Skin cancer is the uncontrolled growth of abnormal skin cells. If left unchecked, these cancer cells can spread from the skin into other tissues and organs.
12.    Head and Neck Cancers: The term head and neck cancer refers to a group of biologically similar cancers originating from the upper aerodigestive tract, including the lip, oral cavity (mouth), nasal cavity, paranasal sinuses, pharynx, and larynx.
13.    Esophageal Cancer: Esophageal cancer is a cancerous (malignant) tumor of the esophagus, the muscular tube that moves food from the mouth to the stomach.
14.   Stomach Cancer: Gastric cancer, commonly referred to as stomach cancer, can develop in any part of the stomach and may spread throughout the stomach and to other organs; particularly the esophagus, lungs, lymph nodes, and the liver.
15.   Liver Cancer: Hepatocellular carcinoma is cancer of the liver.
16.   Anal Cancer: Anal cancer is a type of cancer which arises from the anus, the distal orifice of the gastrointestinal tract.
17.   Kidney Cancer: Renal cell carcinoma is a type of kidney cancer in which the cancerous cells are found in the lining of very small tubes (tubules) in the kidney.
18.   Testis Cancer: Testicular cancer is cancer that develops in the testicles, a part of the male reproductive system.
19.   Gynecological Cancers: Gynecologic cancer is a group of cancers that affect the tissue and organs of the female reproductive system. Each type of cancer is named after the organ it originates.
20.  Choriocarcinoma: Choriocarcinoma is a malignant, trophoblastic and aggressive cancer, usually of the placenta. It is characterized by early hematogenous spread to the lungs. It belongs to the far end of the spectrum of gestational trophoblastic disease (GTD), a subset of germ cell tumors.
21.    Brain Tumors: A brain tumor is an intracranial solid neoplasm, a tumor within the brain or the central spinal canal.
22.   Bone Tumors: A bone tumor refers to a neoplastic growth of tissue in bone. Abnormal growths found in the bone can be either benign (noncancerous) or malignant.
23.   Carcinoid Tumor: Carcinoid tumor is a slow-growing type of neuroendocrine tumor, originating in the cells of the neuroendocrine system.
24.  Nasopharyngeal Cancer: Nasopharyngeal carcinoma (NPC) is a cancer originating in the nasopharynx, the uppermost region of the pharynx or "throat", where the nasal passages and auditory tubes join the remainder of the upper respiratory tract.
25.   Retroperitoneal Sarcomas: Retroperitoneal sarcomas are rare neoplasms.
26.  Soft Tissue Tumors: A soft tissue sarcoma is a form of sarcoma that develops in connective tissue, though the term is sometimes applied to elements of the soft tissue that are not currently considered connective tissue.
