Melanoma skin cancer
This disease develops in the melanocytes, skin cells that produce melanin that gives color. Melanocytes are found in the epidermis, layer of outer skin.
Melanoma is the type of skin cancer less common and more severe. You can easily spread to other parts of the body through blood or lymphatic system. If diagnosed early, the prognosis is better.
It can occur from existing moles, or a new formation, small, pigmented, appearing in an area of normal skin.
Will have to consult with your doctor if you notice a change in the size, shape or color of a mole. Or a mole that is swollen or painful to the touch or oozing or bleeding. Read the rest of this entry »

Kaposi sarcoma in two forms:
That which usually develops in those patients with acquired immunodeficiency syndrome (AIDS) and children and young people of equatorial Africa. This form grows very fast and tends to affect internal organs.
Before the onset of the disease, tended to present only the elderly of European origin Mediterranean. In these people grows very slowly on the skin and rarely spreads.
In the first the characteristic appearance is a sin pink, red or purple round or oval, in any part of the body but more often in the face. Read the rest of this entry »
Types and Description of Skin Cancer
Nonmelanoma skin cancer
Squamous cell carcinoma (or squamous cell carcinoma) develops in the middle layers of the epidermis and accounts for 20% of all cases of skin cancer.
Usually appears in areas that have been exposed to the sun, like the top of the nose, ears, forehead, lip and back of hands.
You can also occur in areas of skin that have been in contact with chemicals, which have undergone radiotherapy, or have been burned. In the genital area, appears less frequently.
Generally tend to have a hard red bump. Sometimes it may look, scaly, or bleed and develop a scab that never heals. As will having enlarged nodular and sometimes presents a warty surface. In the end, it becomes an open sore and grows into the underlying tissue.
Through the lymph system can extend to any part of the body, although this rarely happens. It is a tumor with a tendency to grow and fall in the same place, once removed. But it tends to spread. Read the rest of this entry »
Cancer, skin cancer: prevention by eating broccoli
According to a study by researchers at Johns Hopkins University, broccoli 25% decreases the likelihood of developing skin cancer.
Always known that eating fruits and vegetables is good for the body.
Always doctors and nutritionists recommend eating lots of fruits and vegetables because the beneficial effects on healthy life and to take over five servings per day.

A vaccine will cure skin cancer
A new vaccine being tested gives new hope for treatment of skin cancer. The drug, called “OncoVEX” attacks cancer cells, leaving healthy cells intact, and stimulates the body’s response to melanoma, so patients can fully recover, even those with the disease, advanced.
Dr. Howard Kaufman of the Rush University Medical Center in Chicago said that the vaccine will bring relief to thousands of people with skin cancer every year. The drug not only affects cells that are injected, but also in other parts of the body can not be reached, inducing an immune response by the flow of blood.
The BioVex, manufacturer is currently recruiting more than 400 patients for the final stages of testing, which will be made in the USA and the UK. Read the rest of this entry »
Found a cure for skin cancer
A test vaccine in infancy in England shows its effect has some complete cures melanoma, even at an advanced stage: attack cancer cells while leaving healthy cells intact and significantly increases the immune response to skin cancer.
Dr. Howard Kaufman of Chicago’s Rush University Medical Center, says: “Our studies show clearly that we are: we have a cure for melanoma and develop drugs that could save thousands of lives every year.”
The figures are dramatic: in the last 25 years the rate of melanoma in the UK alone has increased dramatically compared to other types of cancer, and kills more than 2,000 victims a year. Read the rest of this entry »
What is Skin Cancer?
Skin cancer is a disease caused by the development of cancerous cells in any of the layers of the skin.
There are two types: non-melanoma and melanoma.
The non-melanoma cancer is the most common and is called nonmelanoma because they formed from other skin cells are not accumulating pigment (melanocytes). Within this type are all skin cancers less malignant melanoma is less common and more malignant and explained below.
Skin cancer is most prevalent among white skinned people who have spent much time exposed to sunlight, especially when sun exposure occurred in childhood and there were numerous sunburn. Although it may appear anywhere on the skin, is more common than is presented on the face, neck, hands and arms.
This cancer is one of the most common of all cancers, and diagnosed an estimated two million new cases per year worldwide.
In recent years, the incidence of malignant melanoma has increased dramatically, has multiplied by 3.3 in males and 2.5 in women over the last twenty years in Spain. Despite this, less than 3% of all tumors and early detection campaigns have allowed the mortality is reduced by 30% since the seventies.
You can recognize a change in the appearance of the skin, like a wound that does not heal or a small bump. You may also see a red, rough or scaly skin with a tendency to grow.
Any changes or abnormality of the skin, one must see the doctor. It can extract and analyze a sample (biopsy) to check whether a tumor is malignant or not.
