What is Skin Cancer ?

Increasing skin cells in unusual way is called skin cancer, which often comes in contact with sunlight. But skin cancer is often also in those areas of the skin, which are not normally exposed to sunlight.

Skin cancer is mainly of three types - basal cell carcinoma, squamous cell carcinoma and melanoma.Cancer Causes, Types, Treatment, Symptoms ad Signs

Types of Skin Cancer

Basal Cell Carcinoma-

Basal cells produce new skin cells because older people die. Restricting contact with the sun may help prevent these cells from becoming cancerous.

Squamous Cell Carcinoma -

Cancer due to uncontrolled development of abnormal squamous cells.

Melanoma -

it starts in color-production cells (melanocytes) in the skin. The incidence rate is very low, but it is very dangerous compared to the two types of skin cancer above. Melanoma occurs when pigment-producing cells that give skin color, become cancerous.

Symptoms of Skin Cancer

Basal Cell Carcinoma

Basal cells are usually found on the parts of the body, which come in contact with the sun: - face and neck.

It can also be in the following form -

  1. As a pearl or wax-colored bottom on the skin,
  2. In the form of flat, fleshy or brown marks.

Squamous Cell carcinoma

Squamous cell carcinoma occurs only in parts of the body, which come in contact with sunlight such as face, neck, ears and hands etc. Such people are likely to develop 'squamous cell carcinoma' which does not come in contact with Sunburn.

'Squamous cell carcinoma' can occur in the following form.

  1. As a hard and red lump. 
  2. As a flat wound with flake layer.


Melanoma can be developed anywhere in the body, a sesame or wart of normal skin or part of the body can turn into skin cancer. In males 'melanoma' often develops on their face or trunk (abdomen, waist, and chest etc.), and in women it often develops in the lower part of the feet. Men and women can also develop melanoma on those parts of their body, which are not exposed to sunlight.

Melanoma can affect people of every type of skin tone. Often, in people with blurred skin, 'melanoma' develops under their soles and feet or under the feet and nails.Foods That Fight Cancer Naturally.

Symptoms of Melanoma:

With a deep point, large brown mist.
A sesame or a wart, whose color and shape are changing or bleeding with it.
A small wound with temporary edges and stretches, which can be red, white, blue or black-blue.
Dark wounds that can occur in the body in the palms, feet soles, hands and feet, mouth mucous membrane, nose and genitalia.

Causes of Skin Cancer

Squamous cell's

It is below the surface of the skin, which acts as the inner layer of the skin.

Basal Cell

These cells produce new skin cells, which are located just below the squamous cells.


These cells produce "melanin", it is a pigment (substance that provides color), which provides normal color of the skin. It is located in the lower part of the epidermis. When you are in the sun, you begin to make 'melanocytes' and more melanin to protect the inner lining of your skin. It is known that on the basis of skin cancer, its type and treatment options are determined.

Ultraviolet Rays:

In cases of skin cells destroyed by DNA, most are the result of ultraviolet radiation. These radiations are found in sunlight and beds used for light. But due to the exposure of the sun, the cause of skin cancer. it can not be understood, because skin cancer can also occur on those parts of the body which are not exposed to the sun.

Risk Factors for Skin Cancer

White skinned

Well skin cancer can be for any skin tone. But white skin has less pigment (melanin), which can provide less protection than ultraviolet radiation.

Take a Long Time in the Sun

If a person spends too much time in the sun, then the risk of skin cancer can increase. Especially when he has not used clothes or sunscreen etc. to avoid sunlight.

Moles or Wart

Those who have excessive or unusual abnormalities on their body may also be exposed to skin cancer. Unusual malls are those that are temporary, larger than normal mall size. They are more likely to have cancer than normal malls. If such unusual malls are visible on the body then their changes should be monitored regularly.

Pre-cancer Wounds

Skin wounds known as "actinic keratosis" can also increase the risk of developing skin cancer. Pre-cancerous wounds are especially visible in the form of rigid and shiny spots, which can range from brown to black pink.

Weak Immune System

Those who have weakened the immune system, they may be at greater risk of developing skin cancer. People who have HIV (HIV-AIDS) or those taking immunosuppressant medicines after organ transplantation often weaken their immune system.

Exposure to Harmful Substances

If you ever come in contact with some harmful substances like arsenic, then increase the risk of skin cancer. Know About The Most Common Types of Cancer
