Skin Cancer – Cause & Symptoms

Beware of the next moment you’re considering skipping sunscreen! Before arriving, skin cancer does not offer a warning. Skin cancer, however, is the most preventable of all recognized cancers. It requires you only to know what skin cancer is and to know how secure you are.

The damaging radiation from the ultraviolet (UV) rays of the sun is one of the major causes of skin cancer. These rays harm the cells of the skin and make you susceptible. What you have to do is get a lowdown of skin cancer prevention and breathe easily!

What is skin cancer?

Most skin cancers are local cancerous (malignant) skin growth. They are derived from the surface layer of the skin, the epidermis cells. Contrary to malignant cutaneous melanoma, most of these types of skin cancers rarely spread (metastases) to other areas of the body to endanger life.

Three main kinds of skin cancer exist:

(1) the most prevalent baseline carcinoma of the skin,

(2) the second more commonly occurring squamous cell carcinoma of the skin cells and

(3) the melanoma which originates from the pigment-producing skin cells (melanocytes).

Other rare types of skin cancer include lymphoma, Merkel cell and other tissue diseases, including sarcomas, hair, and sweat gland tumors.

Risk Factors For Skin Cancer

The most common risk factors for skin cancer are as follows.

  • Exposure to ultraviolet light from the sun or tanning beds. Particularly susceptible are fair-skinned people with hazel or blue eye, people with red or blonde hair. In elevated altitude or near the equator where exposure to the sun is intensified, the issue is worse.
  • A chronically suppressed immune system (immunosuppression) from underlying illnesses such as infection with HIV / AIDS or cancer, or certain medicines such as prednisone or chemotherapy.
  • Exposure to ionizing radiation (X-rays) or to cancer-prone chemicals such as arsenic
  • Certain kinds of wart virus infections sexually obtained
  • People with a history of one skin cancer have a 20 percent chance in the next two years of developing second skin cancer.
  • Elderly patients have more cancers of the skin.

Causes Of Skin Cancer

Except in rare instances, DNA mutations induced by ultraviolet light affecting cells of epidermis cause most skin cancers. Many of these early cancers seem to be controlled by natural immune control, which allows malignant cells that become tumors after damage to mass development.

Types Of Skin Cancer

There are several different types of skin cancers:

The most prevalent cancer for humans is basal cell carcinoma. Every year in the US, over 1 million cases of fresh basal cell carcinoma are diagnosed. There are several types of basal cell cancer, such as the superficial type, the least worrying type; the nodular type, the most frequent; and the morphic type, the most difficult to treat as the tumors often grow into the surrounding tissue (infiltrate) without any definite border.

Squamous cell carcinoma accounts for approximately 20% of all cancers of the skin, but in immunosuppressed people, it is more common. In most cases, its biological behavior, with a little but significant chance of distant spread, is much like basal cell carcinoma.

Melanoma, Merkel-cell carcinoma, atypical fibroxanthoma, lymphoma dermat of fibrosarcoma, and other common skin cancers are less common.

Signs And Symptoms

Most basal cell carcinomas have few symptoms if any. Squamous cell carcinomas can be painful. Both forms of skin cancer may seem like a sore, which will not cure bleeding, oozes, crusts, or else. They start like a bump that grows slowly on the skin after minor Trauma and can bleed. Both skin cancers may have edges raised and ulceration in the center.

Basal cell carcinoma signs and symptoms are as follows:

  • Looks like bright pink, red, pearly, or translucent bump
  • Pink skin growths or raised boundary lesions crusting in the center
  • An elevated reddish patch of skin that may crust or itch, but is usually not painful

Squamous Cell Carcinomas signs and symptoms are as follows:

  • Persistent red patches with irregular boundaries that can easily bleed
  • Open sore, which will not go away for weeks
  • A higher growth with a rough surface in the center
  • A wart-like growth

Actinic keratoses are scaly, crusty lesions created by ultraviolet light harm often called solar keratoses (AK) in the facial region, scalp, and back of the hand. These are regarded precancers because if untreated, up to 10% of actinic keratoses may evolve into squamous cell carcinomas.

Most Common Sites Where Skin Cancer Develops

Skin cancers typically occur constantly over many years in regions of the skin that are subjected to the sun, such as the face and nose, ears, neck back, and scalp bald region. These tumors may appear less frequently at locations with only restricted exposure to the sun, such as the back, chest, or extremities. Skin cancer, however, can happen anywhere on the skin.


A dermatologist’s skin examination is the way to get a definitive skin cancer diagnosis. The appearance alone is adequate in many instances to make the diagnosis.

Usually, a skin biopsy is used to verify a skin cancer suspicion. This is accomplished by numbing the tumor region with a local anesthetic such as lidocaine. A tiny part of the tumor is cut away by a pathologist who examines the tissue under a microscope and makes a diagnosis based on the tumor’s features.


There are several efficient ways to treat cancer of the skin. The treatment selection relies on the tumor’s place and size, cancer’s microscopic features, and the patient’s overall health.

  • Freezing: By freezing them with fluid oxygen (cryosurgery), your doctor may kill actinic keratoses and some tiny, early skin cancers. When it thaws, the dead tissue sloughs away.
  • Mohs surgery: This operation is for skin cancers that are bigger, recurrent or difficult to treat, which may include both basal and squamous cell carcinomas. It is usually used in fields where the skin needs to be kept as much as possible, such as on the nose.

During Mohs surgery, your physician will remove the skin growth layer by layer and examine each layer under the microscope until no abnormal cells remain. This operation enables the removal of cancer cells without getting too much good skin around.

  • Radiation therapy: Radiation treatment utilizes powerful power beams, such as X-rays, to kill cancer cells. If cancer can’t be totally removed during the surgery, radiation therapy can be an alternative.
  • Chemotherapy: Drugs are used in chemotherapy to destroy cancer cells. For cancers restricted to the top layer of skin, it is possible to apply creams or lotions containing anti-cancer agents straight to the skin. It is possible to use systemic chemotherapy to treat skin cancers that have spread to other areas of the body.
  • Photodynamics Therapy:  With a mixture of laser light and drugs, this therapy destroys skin cancer cells that make cancer cells susceptible to light.
  • Biological therapy:  Biological therapy utilizes the immune system of your body to kill cells of cancer.

Is It Possible To Prevent Skin Cancer?

Avoiding triggers that cause tumors to grow can prevent many skin cancers. Prevention strategies include sunscreen protection, protective clothing, and sun prevention during the 9 a.m. peak hours. to 3 p.m. Parents should protect kids from the sun. Do not use tanning beds that are a major cause of ultraviolet light exposure and an important skin cancer risk factor.

The therapy of skin cancer is as fatal as it sounds when it is caught in the early phases. However, prevention is always better than treatment. Step away from excessive sun exposure. Wear protective clothing and never skip the sunscreen. Make sure you also teach your kids about and how to prevent skin cancer. Stay Safe!!!
