Here are the different types of cancer that you can come across and write about or get to know more about. Help taken from googled websites that explained each cancer thoroughly;

Acute lymphoblastic leukaemia [ALL]

Leukaemia is a cancer of the white blood cells. People with leukaemia usually have more white blood cells than normal. Leukaemia cells behave differently from healthy white blood cells.

Acute Myeloid Leukaemia [AML]

In AML, too many early myeloid cells are made. In most types of AML, the leukaemia cells are immature white blood cells. In some less common types of AML, too many immature platelets or immature red blood cells are made.

The immature cells fill up the bone marrow, taking up space that's needed to make normal blood cells. Some leukaemia cells 'spill over' into the blood and circulate around the body in the bloodstream.

Anal Cancer

A cancer (malignant tumor) which arises from the anus, the distal opening of the gastrointestinal tract.

Adrenocortical Carcinoma

Adrenocortical carcinoma is a rare disease in which malignant (cancer) cells form in the outer layer of the adrenal gland. There are two adrenal glands. The adrenal glands are small and shaped like a triangle. One adrenal gland sits on top of each kidney. Each adrenal gland has two parts.

Kaposi Sarcoma

Kaposi's sarcoma is a cancer that causes patches of abnormal tissue to grow under the skin, in the lining of the mouth, nose, and throat or in other organs.

AIDS-related lymphoma

People with HIV (human immunodeficiency virus) have a weakened immune system. As a result, they are more likely to develop certain cancers. This includes non-Hodgkin's lymphoma (NHL). Also known as AIDS-related lymphoma, this is a cancer of white blood cells. White blood cells fight infection.

Appendix Cancer

Appendix cancer or appendiceal cancers are rare malignancies of the vermiform appendix. Gastrointestinal stromal tumors are rare tumors with malignant potential. Primary lymphomas can occur in the appendix. Breast cancer, colon cancer, and tumors of the female genital tract may metastasize to the appendix.

Basal Cell Carcinoma [BCC]

Basal cell carcinoma is a type of skin cancer. Basal cell carcinoma begins in the basal cells - a type of cell within the skin that produces new skin cells as old ones die off.

Basal cell carcinoma often appears as a waxy bump, though it can take other forms. Basal cell carcinoma occurs most often on areas of the skin that are often exposed to the sun, such as your face and neck.

Bile Duct Cancer

These cancers develop in the smaller bile duct branches inside the liver. They can sometimes be confused with cancers that start in the liver cells, which are called hepatocellular carcinomas, and are often treated the same way. Only about 1 in 10 bile duct cancers are intrahepatic.

Bladder Cancer

Bladder cancer is a malignant tumour that starts in the cells of the bladder. Malignant means that it can spread, or metastasize, to other parts of the body.

Rare types of bladder cancer can also develop. These include squamous cell carcinoma and adenocarcinoma. Urothelial carcinoma can also start in the renal pelvis or ureters, but this is less common.

Bone Cancer

Bone cancer is an uncommon cancer that begins in a bone. Bone cancer can begin in any bone in the body, but it most commonly affects the long bones that make up the arms and legs.

Several types of bone cancer exist. Some types of bone cancer occur primarily in children, while others affect mostly adults.

The term "bone cancer" doesn't include cancers that begin elsewhere in the body and spread (metastasize) to the bone. Instead, those cancers are named for where they began, such as breast cancer that has metastasized to the bone.

Types of Bone Cancer;
Ewing Sarcoma
Osteosarcoma and Malignant Fibrous Histiocytoma

Brain Stem Glioma

Childhood brain stem glioma is a disease in which benign (non cancer) or malignant (cancer) cells form in the tissues of the brain stem. Brain tumors may be benign (not cancer) or malignant (cancer).The cause of most childhood brain tumors is unknown.

Brain Tumor

A brain tumor is a collection (or mass) of abnormal cells in the brain. The skull is very rigid and the brain is enclosed, so any growth inside such a restricted space can cause problems. Brain tumors can be cancerous (malignant) or non-cancerous (benign).

Types of Brain Tumor;
Astrocytomas, Childhood
Brain and Spinal Cord Tumors Treatment Overview, Childhood
Brain Stem Glioma, Childhood
Central Nervous System Atypical Teratoid/Rhabdoid Tumor, Childhood
Central Nervous System Embryonal Tumors, Childhood
Central Nervous System Germ Cell Tumors, Childhood
Craniopharyngioma, Childhood
Ependymoma, Childhood

Breast Cancer

It is a malignant tumor that starts in the cells of the breast. A malignant tumor is a group of cancer cells that can grow into (invade) surrounding tissues or spread (metastasize) to distant areas of the body. The disease occurs almost entirely in women, but men can get it, too.

Bronchial Tumors, Childhood

The term bronchial adenoma describes a diverse group of tumors arising from mucous glands and ducts of the trachea (windpipe) or bronchi (large airways of the lung).

Burkitt Lymphoma

Burkitt lymphoma is a form of non-Hodgkin's lymphoma in which cancer starts in immune cells called B-cells. Recognized as the fastest growing human tumor, Burkitt lymphoma is associated with impaired immunity and is rapidly fatal if left untreated.

Carcinoid Tumor

Carcinoid tumors are a type of slow-growing cancer that can arise in several places throughout your body. Carcinoid tumors, which are one subset of tumors called neuroendocrine tumors, usually begin in the digestive tract (stomach, appendix, small intestine, colon, rectum) or in the lungs.

Central Nervous System

A central nervous system (CNS) tumor begins when healthy cells in the brain or the spinal cord change and grow uncontrollably, forming a mass. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body.

Cervical Cancer

Cervical cancer is a cancer arising from the cervix. It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body. Early on, typically no symptoms are seen. Later symptoms may include abnormal vaginal bleeding, pelvic pain, or pain during sexual intercourse

Cholangiocarcinoma

Cholangiocarcinoma is a form of cancer that is composed of mutated epithelial cells (or cells showing characteristics of epithelial differentiation) that originate in the bile ducts which drain bile from the liver into the small intestine.

Colon Cancer

Colon cancer most often begins as clumps of precancerous cells (polyps) on the inside lining of the colon. Polyps can appear mushroom-shaped, or they can be flat or recessed into the wall of the colon. Removing polyps before they become cancerous can prevent colon cancer.
