Why are there different types of cancer?

But vary in some ways because body organs do very different things. For example, nerves and muscles do different things, so the cells have different structures. There are more than 200 types of cancer and we can classify cancers according to where they start in the body, such as breast cancer or lung cancer.

Why are different types of cancers named based on where in the body they originate?

Types of cancer are usually named for the organs or tissues where the cancers form. For example, lung cancer starts in the lung, and brain cancer starts in the brain. Cancers also may be described by the type of cell that formed them, such as an epithelial cell or a squamous cell.

How are the different types of cancer categorized?

Cancers are classified either according to the kind of fluid or tissue from which they originate, or according to the location in the body where they first developed. In addition, some cancers are of mixed types.

What is the difference between carcinoma and lymphoma?

Carcinomas — the most commonly diagnosed cancers — originate in the skin, lungs, breasts, pancreas, and other organs and glands. Lymphomas are cancers of lymphocytes. Leukemia is cancer of the blood. It does not usually form solid tumors.

Is there a difference between sarcoma and carcinoma?

Carcinomas are cancers that develop in epithelial cells, which cover the internal organs and outer surfaces of your body. Sarcomas are cancers that develop in mesenchymal cells, which make up both your bones and soft tissues, such as muscles, tendons, and blood vessels.

What kind of cancer is sarcoma?

A sarcoma is a type of cancer that starts in tissues like bone or muscle. Bone and soft tissue sarcomas are the main types of sarcoma. Soft tissue sarcomas can develop in soft tissues like fat, muscle, nerves, fibrous tissues, blood vessels, or deep skin tissues. They can be found in any part of the body.

What type of cancer is carcinoma?

Carcinoma is a type of cancer that starts in cells that make up the skin or the tissue lining organs, such as the liver or kidneys. Like other types of cancer, carcinomas are abnormal cells that divide without control. They are able to spread to other parts of the body, but don’t always.

What is the difference between lymphoma and sarcoma?

Lymphomas are cancers of lymphocytes. Leukemia is cancer of the blood. It does not usually form solid tumors. Sarcomas arise in bone, muscle, fat, blood vessels, cartilage, or other soft or connective tissues of the body.

What are the differences between sarcoma and carcinoma in macroscopic and microscopic features?

Carcinomas arise out of epithelial cells that line the surface and organs of the body, whereas sarcomas arise from connective tissues such as bone, cartilage, fibrous tissue, blood vessels, and nerves.

Is sarcoma an aggressive cancer?

This is an extremely rare form of soft tissue sarcoma that usually arises in the abdomen or pelvis, although it can develop elsewhere in the body. It is aggressive and often spreads to other areas of the body, particularly the lungs or liver. These tumors can cause pain and a mass can usually be felt in the abdomen.
