Cancer is the term for a collection of similar syndromes due to which, cells in the body lose their balance. The cells keep dividing and breaking continuously and spread into surrounding tissues.
The human body is made up of billions of cells, and new cells are created once the older ones get damaged. When the body develops cancer, this orderly process stops, and the batteries work abnormally. Batteries do not die when they arrive used or old and new cells, on the other hand, grow when they are not required.
Cancers may form solid tumors which are masses of tissues at any part of the body. Again, the blood-related diseases have no such external effects and are more malignant and spread faster than the rest. Except for brain tumors (mostly life-threatening) others, types of tumors do not spread easily. They vary in size and once removed, do not grow back quickly. The case is just the opposite for the malignant tumors.
Types of Cancer
Take a look at some of the most common forms of cancer:
These are the most common types of cancers and are caused by epithelial cells. These are the cells that cover the inside and outside surfaces of the body. There are four main types of Carcinoma:
- Adenocarcinoma is the type which usually forms in the epithelial cells which release fluids or mucus. The tissues containing such cells are commonly known as glandular tissues. Examples of cancers falling under this category are breast, colon, and prostate cancers.
- The next is the Basal cell carcinoma, and the name says it all. This cancer usually begins from the lower or the base layer of the epidermis, which is a person’s outer layer of the skin.
- Squamous cell carcinoma or epidermoid Carcinoma is the type which begins from the layer beneath the basal cell. This layer is said to cover some of the vital organs such as the stomach, intestine, lungs, bladder, and kidney.
- Transitional cell carcinoma forms in the epithelial tissue or urothelium. This tissue is made up of several epithelial cells that get bigger or small. Cancers in the bladder, kidneys, and ureters are examples falling under this category.
Sarcomas are the cancers which usually form in bones and soft tissues of the body. The commonly infected parts are muscles, fat tissues, blood vessels, lymph vessels, and the fibrous tissues for examples tendons and ligaments. Osteosarcoma is the most common type of Sarcoma cancer.
The diseases that begin in the blood-forming tissues of the bone marrow are termed as leukemia. There are no solid tumors formed on the body in this case. Instead, what happens is an increase in the number of white blood cells in the body. The result of this abnormal change is that the healthy blood cells are overpowered by the damaged, white cells, due to which proper oxygen supply to the tissues is snapped. This activity brings down the immunity level of the human body tremendously.
This cancer begins in the lymphocytes or T-cells and B-cells. These cells are immunity of white blood cel
