Skin Cancer: Causes, Symptoms, and Prevention

Skin cancer is one of the most common types of cancer in the world. It is a disease that affects the skin. It usually starts when skin cells grow uncontrollably and form a tumour. Skin cancer is mainly caused by exposure to ultraviolet light from sunlight. This UV light damages DNA in the skin cells and it often leads to cancer. People with fair skin are at a higher risk of developing this type of cancer than people with darker skin. People who have had excessive exposure to the sun are also at higher risk. 

The most common type of skin cancer is basal cell carcinoma, followed by squamous cell carcinoma and melanoma.

Basal Cell Carcinoma: It arises from basal cells, which are found at the bottom layer of the epidermis. It can develop in any part of the body but is usually most common in the upper half of the face.

Squamous Cell Carcinoma: It appears as an open sore or ulcer that may crust over or bleed. 

Melanomas: Usually black or brown in appearance and they grow quickly, sometimes within weeks or months.

Causes of Skin Cancer

Exposure to harmful UV rays

Skin cancer is the abnormal growth of skin cells that can occur in any part of the body. It can be caused by UV rays exposure.

Xeroderma pigmentosum

This is a rare genetic skin condition in which the skin is unable to repair UV damage. Most people with this condition can develop skin cancer on exposure to UV rays.


The majority of birthmarks are harmless and do not pose a risk for skin cancer. There is, however, a chance that some birthmarks in the outer layer of the skin may develop into cancer. 

Radiation Treatment

Radiation exposure can lead to skin cancer. People who undergo radiation treatment may develop cancer in an area of treatment. Also, technicians who work in close exposure to radiation may develop it in the long run. 


The risk of skin cancer increases with some occupations as they involve working with certain chemicals such as petroleum products, arsenic, coal tar, creosote, soot, shale oils, etc.
