Cancer May Spread From Where It Began To Other Parts Of The Body
When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began and travel through the lymph system or blood.
- Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor in another part of the body.
- Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor in another part of the body.
The metastatic tumor is the same type of cancer as the primary tumor. For example, if skin cancer spreads to the lung, the cancer cells in the lung are actually skin cancer cells. The disease is metastatic skin cancer, not lung cancer.
Staging For Basal Cell Carcinoma And Squamous Cell Carcinoma Of The Skin Depends On Where The Cancer Formed
Staging for basal cell carcinoma and squamous cell carcinoma of the eyelid is different from staging for basal cell carcinoma and squamous cell carcinoma found on other areas of the head or neck. There is no staging system for basal cell carcinoma or squamous cell carcinoma that is not found on the head or neck.
Surgery to remove the primary tumor and abnormal lymph nodes is done so that tissue samples can be studied under a microscope. This is called pathologic staging and the findings are used for staging as described below. If staging is done before surgery to remove the tumor, it is called clinical staging. The clinical stage may be different from the pathologic stage.

The skin does many things. It:
- protects the body from injury and infection
- helps to control body temperature
- helps to control fluid loss
- gets rid of waste substances through the sweat glands.
The skin is divided into 2 main layers. The outer layer is the epidermis and the layer underneath is the dermis. Below these is a deeper layer of fatty tissue.
The epidermis contains several types of cells. Most of the epidermis is filled with cells called keratinocytes, also called squamous cells.
The lowest layer of the epidermis is called the basal layer. It contains rounder cells called basal cells.
The basal layer also contains skin cells called melanocytes which produce melanin. Melanin gives skin its natural colour.

Almost All Of Them If Diagnosed And Treated Early Will Be Cured If Not All Three Skin Cancer Types Can Be Dangerous Disfiguring And Deadly
In a recent study, the development of non-melanoma type skin cancers in male mice exposed to UVB light was 50 percent lower in those fed a diet of 10 percent dehydrated tomato powder when compared to controls.
The three most common skin cancer types are melanoma, basal cell carcinoma, and squamous cell carcinoma, and the number of Americans who get one or more forms continues to increase. Nearly half of Americans who live to be 65 will develop some type of skin cancer. Almost all of them, if diagnosed and treated early, will be cured. If not, all three skin cancer types can be dangerous, disfiguring, and deadly.

Melanoma is the deadliest of all skin cancer types, yet the cure rate, with early detection and treatment, is 99 percent. Unfortunately, too many people delay treatment, even when they know they have a potentially life-threatening disease. The average age of people diagnosed with melanoma is 62, but it can begin at almost any age.

Any cancer is the uncontrolled growth of cells in the body, and skin cancer is a cancer that affects the cells in the skin. Its very common in Australia, with 2 in 3 Australians diagnosed with a form of skin cancer before the age of 70. You can learn more about skin cancer here.

Can You Prevent Skin Cancer
According to Dr. Dorsey, Skin cancer is an extremely serious condition, but with proactive care, most cases can be avoided altogether. In fact, taking a few small steps to limit sun damage and conducting regular skin self-exams is all you need to do to keep your skin healthy. Because sun exposure is the main underlying cause of skin cancer, sun protection is essential to prevent this condition. Patients need to apply sunscreen every day and reapply at least every two hours during prolonged sun exposure. Whenever possible, limit or avoid time spent outdoors during peak sun hours between 10 am and 4 pm. If patients need to be outdoors during these times, its important to wear protective coverings, seek shade, and reapply sunscreen frequently.
In addition to daily sun protection steps, patients also need to perform self-exams at least every month. Early detection is key to providing effective skin cancer treatment, so regular self-exams are an essential part of keeping people healthy. Your Board Certified Dermatologist can walk you through a self-exam when you visit the office, but the basic process involves carefully examining your skin, from the top of your head to the bottoms of your feet , and noting any spots, lesions, bumps, discoloration, or other skin changes or irregularities. When you know where marks are on your skin, youll be more likely to notice if they are growing or changing in ways that are concerning or that indicate skin cancer.
