The causes of skin cancer, symptoms and treatment

Skin cancer is more likely to occur among the white people, the Indians or black peoples are not more less then suffering from this disease . The sun’s ultraviolet rays on the skin, is the most causes of skin cancer. However, skin cancer can also occur in areas of the skin that are not exposed to sunlight. It is proven that, the UV rays of the sun are mainly responsible for skin cancer.

The causes of skin cancer:

The factors that increase the risk of this cancer –

This is mostly caused by the ultraviolet rays of the sun. This cancer occurs when UV rays of the sun are absorbed through the skin for a long time. The skin of Indian subcontinent has a higher level of melanin which protects us from the harmful effects of the sun’s ultraviolet rays. Compared to the skin of the white people, the level of melanin is much lower and they have a high risk of this cancer due to their tendency to sun bath.

Some medications such as prednisone or chemotherapy weaken the body’s immune system. The people of HIV or AIDS positives and the people who take immunosuppressant drugs after organ transplants are also at risk of this cancer.

Severe skin damage and even cancer can be causes of Arsenic exposure.

If someone in your family had this disease or if you have had it once, there is a chance that it will come back within the next two years.

How many types of skin cancer? And what are the symptoms?

In which part or cell of a person the skin cancer starts, this way can be know the type of this cancer. When the cancer starts in the cells known as basal cells a person is then infected basal cell carcinoma. Skin cells that give our skin color are called melanin, when cancer starts from melanin it is called melanocarcinoma.

Let’s look at the most common skin cancers and how they manifest.

Basal Cell Carcinoma: –

Basal cell carcinoma is one of the most common types of skin cancer. This type of cancer is usually caused by UV rays to the white-skinned people. In this case, the white or pink sore wax-like swollen part spreads all over the body including the scalp, neck, chest, hands and feet, lower abdomen. At the primary steps diagnosis is very important. Because basal cell carcinoma has the tendency is to spread inner parts of the body. If you don’t take initiative for a long time, it can penetrate the nerves and bones of the body and damage them.

Squamous cell carcinoma: –

It can be infected in any part of the skin. It starts first with sores that don’t want to dry quickly. These are called actinic keratoses, which are not cancer at first. If it will left untreated for a long time, red or brown-colored swollen areas are formed from here, which start from the edges of the ears, hands, face, neck, chest, back and slowly spread throughout the body. Later it reaches deeper part into the skin. Early detection and treatment can prevent this cancer from spreading to inner parts of the body.


Melanocarcinoma It is the most dangerous of all skin cancers. This cancer can spread into the whole body very quickly. This cancer can start from any mole or wart on the body or through dark spots of the skin. As possible as early diagnosis and treatment is very important.

Overall, it is important to remember that if you notice any new or different spots on your skin, or itching or bleeding, then definitely met with a dermatologist. So that no skin related diseases can spread in the body.

How is the skin cancer diagnosed?

If there is a suspicious area of ​​skin is found, the doctor will first begin with various tests, noting the size, shape, color of the sore area or swelling, as well as whether there is any bleeding. This cancer diagnosis usually begins with a visual examination.

The doctor may consider these factors when choosing the diagnostic tests:

  1. Patient symptoms and physical condition
  2. Patient’s age and general health
  3. Results of previous medical examinations

Dermatoscopy:- Dermatologist may use a special magnifying lens or microscope for better examine the suspicious area of ​​the patient’s skin, this procedure is called dermatoscopy.

Biopsy:- A sample of the affected area of ​​skin may be taken for biopsy to see if it is cancer. It identifies the type of cancer also.

Imaging tests – Some imaging tests are also done to check whether nearby lymph nodes have become enlarged, whether the cancer has spread to the bones or other parts of the body. For example-

CT scan



These imaging procedures are non-invasive and painless.

Treatment of skin cancer:

Skin cancer treatment depends on the size, type, depth, spread and location of the lesions caused. If cancer is identified  in the early stages, it can be easily treated by removing the harmful lesions on the skin, these harmful lesions or lesions are treated in different ways, such as-


The cancer cells are destroyed by freezing them with extreme cold through liquid nitrogen. As a result, the cells are removed without any damage from the skin. Freezing/Cryosurgery applied most common in the treatment of Acinic Keratosis.

Excisional Surgery:-

If the skin disease makes a large swelling or lesion, it is removed through surgery.

Mohs Surgery:-

Mohs surgery is a special surgical technique, through which thin layers of cancerous skin are removed one by one and the presence of cancer is also checked. This process is continued until there is a layer of healthy and normal cells free of cancer. It is often used in areas of the body where it is necessary to preserve as much skin as possible, such as the nose.

This procedure removes cancer affected cells instead of excess healthy skin.

Curettage and electrodesiccation or cryotherapy:-

Cancer cells are removed using a special device called curette. Then the remaining cancer cells are burned and destroyed through electrocautery needle (an electric needle).


The upper layer of the skin where is confined cancer, anti-cancer creams or lotions containing can be applied directly to the skin, but chemotherapy is used to kill cancer cells that have spread deeper into the skin and elsewhere.

Radiation Therapy:-

Radiation therapy uses high-energy beams to kill cancer cells like X-rays. Radiation therapy may be an option if the cancer cannot be completely removed with surgery.

Photodynamic Therapy:-

In this treatment, the cancer cells are destroyed using laser light and drugs combination.

How skin cancer can be prevented?

The risk of skin cancer can be avoided by following these steps.

  1. Daily use of sunscreen with SPF 30+. Remember; apply sunscreen at least half an hour before going out in the sun, not in to the sun going out time.
  2. Wear always full body covered clothing, UV-blocking sunglasses and a full-round hat or umbrella in the sun.
  3. Avoid going out when there is strong sun.
  4. Use Sun Control Glass Film on car and house windows.
