Skin cancer types

When the skin looses the capacity to grow normally and skin tissues develop uncontrollably, skin cancer appears. In this disease, abnormal cells originate in the skin and grow in large numbers, thereby forming a huge mass called as the tumor. It may not be fatal in case the abnormal growth of the skin cells is limited to few cell layers and the tumor does not spread to surrounding organs and tissues. However, in cases, where the skin tumor spreads to other parts and there is abnormal regeneration of cells, the tumor assumes a life-threatening form, causing great damage to the human body.

Types of skin cells

Some form of cancer cells spreads out and starts affecting nearby healthy cells, thereby forming new tumors. However, most skin cell growth is benign and does not cause malignant tumor. Skin cancer first appears in the outer layer of the skin called the epidermis, which has three kinds of cells-basal, squamous cells and melanocytes. Chief skin cancer cells are also named after these skin cells.

Cells that increasingly roll out and fill the outside of the skin with an insoluble and strong protein called protective keratin that makes the skin waterproof are called as squamous cells.

Small cells that are found at the base of the outer layer of the skin and serves as a reservoir for squamous cells are called as basal cells.

Skin cells that generate dark matter or color that is responsible for giving skin its color is called Melanocytes.

When does skin cancer appear?

Skin cancer appears when each of these cells starts to divide and grow unusually and become dangerous to health. When certain skin cells inside the body changes in their appearance and functioning, skin cells assume a cancerous form. They begin growing and multiplying in an uncontrollable manner in place of dividing and growing in an orderly way. Abnormal cell growth may spread to other parts of the body and tissues, causing great damage.

Various types of skin cancer

There are mainly three types of skin cancer:

Squamous Cell Carcinoma: This type of skin cancer mostly occurs in body parts that are exposed to harmful sun rays for a longer period of time. In this cancer form, skin cells grow abnormally in organs such as face, mouth, and ears. People suffering from squamous skin cancer form may get a small bump on the surface of their skin that turns into an open sore and appears as a flat and crusty bump, as you can see in the picture.

Squamous Cell Carcinoma

If this skin cancer type is not detected earlier then the open sore may get larger and as it grows, there will be less chance of its healing. One should go for prompt treatment as soon as the person is diagnosed with squamous cell carcinoma because it may cause the cancerous skin cells to spread to other vital parts of the body such as the bloodstream, nerve routes and the lymphatic system.

Spread of cancerous squamous cells to other organs of the body occurs gradually and happens in very few cases. If left untreated for long, these cells spread first to the nearest lymph nodes structures and then slowly to other parts. If this cancer is detected at an early stage when the cells spread only as far as the lymphatic system, then lymph nodes can be removed in order to prevent the spread of the cancer.

Basal cell carcinoma: Most of the skin cancers are basal cell carcinoma. It is the most common and also a fatal form of cancer. In this cancer form, the skin cells grow and spread slowly. Almost 75% of the people diagnosed with skin cancer suffer from basal cell carcinoma. In this form of cancer, skin cells in the face, neck, and hands multiply in uncontrollable manner. A patient suffering from this type of skin cancer may develop a sore that oozes blood. He may get a pink pearly bump that causes sever pain and irritation. Redness around the affected area and skin irritation may occur. Appearance of a scar-like yellow or white area is also a symptom of this cancer. If detected in the early stages (every one can do it, just check the picture from our site), basal cell carcinoma can be treated effectively.

Basal Cell Carcinoma

Malignant melanoma: It is one of the most dangerous forms of skin cancer that spreads quickly to other parts of the body, causing significant damage to the health and sometimes resulting in death. Skin cancerous cells may spread rapidly to body parts such as lymp nodes and internal organs.
