Skin cancer is the most common type of cancer among people who work or play sports outside and among sunbathers.
Fair skinned people who produced less melanin are particularly susceptible to developing most forms of skin cancer.
The protective pigment in the outer epidermis; the melanin helps protect the skin from ultraviolet radiation of the sun.
However, dark-skinned people and people whose skin has not had significant sun exposure can have skin cancer. Years after x-ray therapy, or exposure to substances that can cause sin cancer, skin cancers may also develop.
Types of Skin Cancer
The three main types of Skin cancer are;
Basal cell carcinoma
Squamous cell carcinoma
When treated at an early stage most skin cancers are curable. Initially, cancers do not give any symptoms.
In lieu of this, any unusual skin growth that enlarges or lasts for more than a few weeks should be examined by a doctor.
Skin cancer occurs when there’s a mutation in the DNA of the skin cells.
This causes the cells to grow out of control and form a mass of cancer cells.
It begins in the epidermis. The epidermis as stated earlier is the outer layer of the skin that serves as a protective cover that the body continually sheds.
The damage to the DNA in skin cells is mostly caused as a result of much ultraviolet radiation found in the sunlight and in the lights for tanning beds.
But sun exposure does not explain skin cancers that develop on skin not ordinarily exposed to sunlight.
This means that other factors may contribute to risk of skin cancer.
The following factors may also increase your risk of skin cancer
A history of sunburns
Precancerous skin lesions
Family history of cancer
Exposure to radiation
weakened immune system
Since many skin cancers seem to be related to ultraviolet exposure, doctors recommend a number of measures to limit UV exposure.
Such measures are;
1. Avoiding the sun
2. Wearing protective clothing
3. Using sunscreen
4. Avoid tanning beds
5. Be aware of sun-sensitizing medications
6. Check your skin regularly and report changes to your doctor.
Most skin cancers are removed surgically, and the scar that is left after the surgery depends on the size of the original cancer.
More invasive cancer may require removal of a significant amount of skin.
With a skin graft, a piece is removed from another area of the person’s body.
With a skin flop, doctors transfer skin from an adjacent area to replace where the cancer was removed.
With the aforementioned ,We’ve brought to your notice what skin cancer is all about,causes ,prevention and treatment.
