Why It’s Important To Get Screened For Skin Cancer

Skin health, particularly getting you skin checked for the onset of cancers or other conditions, is an essential part of healthcare that many people overlook. According to Healthline, millions of people are diagnosed with skin cancers every year, and if left untreated, the diseases can spread throughout your body and have a significant impact on your health and your body’s aging. 

While melanoma and other skin cancers are quite common, they are fortunately not often lethal — provided that skin cancer signs are detected and treated early to prevent the disease’s spread. Caucasian people are 20 times more likely to develop melanoma then people of African descent, however, roughly 95% of Caucasians survive melanoma, while just 70% of African Americans do. Regardless, the key to avoiding serious skin health issues and skin cancers is regular skin checks to facilitate the early detection of issues.

Types Of Skin Cancer

Basal Cell Carcinoma

Basal cell carcinoma is one of the most common forms of skin cancer. According to the American Cancer Society, nearly 80% of the approximately 3 million new cases of skin cancer diagnosed per year are basal cell carcinoma. This type of skin cancer is slow-growing and develops in the basal cell, the lowest part of your skin’s outermost layer, the epidermis. Basal cell carcinoma most often develops in the areas of your skin that receive the most sun exposure, such as your head and neck. Basal cell carcinoma doesn’t often spread unless left untreated for a long period of time. However, those who do develop basal cell carcinoma once are much likelier to develop it again in the future. 

Recurrent Basal Cell Carcinoma

While basal cell carcinoma doesn’t spread through the body quickly, it is very likely to reappear on the body after it has been diagnosed and treated once. According to the American Cancer Society, half of all patients that are treated for basal cell carcinoma experience a recurrence of the cancer within five years of their first diagnosis. In other words, while this particular type of skin cancer isn’t as dangerous as other types, it is very difficult to keep away permanently once it has developed for the first time.

Squamous Cell Carcinoma

Squamous cell carcinoma is another common type of skin cancer, accounting for nearly 20 percent of all skin cancer diagnoses. This type of skin cancer develops in your epidermis and most often affects a person’s neck, ears, face, and hands, but it can also be found in other areas, such as on scars, ulcers, or in your gential area. 

Squamous cell carcinoma is only slightly more likely than basal cell to spread throughout the body, however, it is much more likely to penetrate deeper into your skin to your fatty tissue, making it more difficult to treat and remove. 


Melanoma is a very complex type of skin cancer that requires expert care to treat. Melanoma develops in melanin, the pigment in your skin that protects your body from UV damage and controls your skin color. Because of this, melanoma is particularly dangerous — not only can it spread to other parts of your body quickly, but it can also develop in nearly any area on your body, including your eyes! To catch melanoma early, it’s essential that you get your skin checked at least once a year.

Merkel Cell Carcinoma

Merkel cell carcinoma is a rare but aggressive form of skin cancer that develops in your skin’s nerve endings, often on the face or scalp. Merkel cell carcinoma is dangerous because it can metastasize to the brain, bones, liver, or lungs. Immunocompromised people over the age of 50 are more susceptible to merkel cell carcinoma than others.

Top Skin Cancer Signs To Watch For

Beyond annual skin health screenings at Kallgren Dermatology, one of the best things you can do to avoid skin cancer is to perform self-checks. Monitoring your skin for any changes or the development of any growths or discoloration will help you spot the symptoms that our dermatologists can evaluate and treat. 

To perform a monthly self-check, examine your body in a full-length mirror in a well-lit room. Follow the ABCDE method:

  • A — Asymmetry. Look for moles or birthmarks in which one half does not match the other in shape or size. 
  • B — Border. Check to see if the borders on any birthmarks or moles are irregular, jagged, or blurred. 
  • C — Color. If you see any irregularities in color on any moles on your body, call our dermatology clinic and schedule an evaluation.
  • D — Diameter. You do not want any spots or moles on your body to exceed a quarter-inch in width. If they do, schedule a skin health screening.
  • E — Evolving. If any of your moles, spots, or birthmarks are changing in size, shape, or color, get a dermatologist’s help right away. 

Overall, you’re looking for the development of any marks or growths that seem unusual, or changes to any spots or moles you already have. We don’t expect you to be able to discern skin cancer symptoms from acne or natural skin imperfections, but if you spot anything on your skin that is changed or that looks abnormal, give Kallgren Dermatology Clinic a call. The combination of monthly self-checks and annual skin health screenings will help keep you healthy so you can continue to enjoy the year-round Boulder sunshine for years to come.
