Most skin cancers are caused by long term exposure to the sun. There are two types of non melanoma skin cancer, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). A history of sunburn increases the risk of BCC. Risk is especially high if you had several episodes of sunburn in childhood. The risk of SCC is linked to overall sun exposure through your life. This means that outdoor workers have an increased risk, such as, farm workers, gardeners and building site workers. Sunburn in childhood is also linked to SCC in some studies.
Fair skinned people, with light coloured hair and eyes, or those more likely to burn than tan, are more at risk of sun damage than dark skinned people.

Skin Cancer Causes
Ultraviolet (UV) light exposure, most commonly from sunlight, is overwhelmingly the most frequent cause of skin cancer.
Other important causes of skin cancer include the following:
* Use of tanning booths
* Immunosuppression—impairment of the immune system, which protects the body from foreign entities, such as germs or substances that cause an allergic reaction. This may occur as a consequence of some diseases or can be due to medications prescribed to combat autoimmune diseases or prevent organ transplant rejection.
* Exposure to unusually high levels of x-rays
* Contact with certain chemicals—arsenic (miners, sheep shearers, and farmers), hydrocarbons in tar, oils, and soot (may cause squamous cell carcinoma) Regarding your mother's comment, people who had at least one severe sunburn early in life have a greater risk of developing skin cancer. Mom is right! Treatment for basal cell carcinoma and squamous cell carcinoma is straightforward. Usually, surgical removal of the lesion is adequate. Malignant melanoma, however, may require several treatment methods, including surgery, radiation therapy, and chemotherapy. ..........................
