On the Surface and On the Rise
Skin cancer is consistently reported to be the most common form of cancer in the United States, affecting more than one million people every year – many of whom are 65 years of age or older. While many are aware of the three types of skin cancer – basal cell carcinoma, squamous cell carcinoma, and melanoma – the actual development of skin cancer may not be as well known. Below you will learn how skin cancer forms, the differences between the three types, and how your ageing loved ones can identify and reduce the risk of skin cancer.
Development and Types of Skin Cancer
The outer-most layer of our skin, known as the epidermis, is composed of three cells: squamous, basal, and melanocytes. Over time, as ultraviolet rays (from the sun or artificial sources like tanning beds) come into contact with the skin, DNA within the skin cells can become damaged, resulting in mutations. These mutations can then cause skin cells to multiply in quick succession, eventually invading the dermis layer of the skin. The classification of skin cancer depends solely on the epidermal skin cell from which it originated.
Basal cell and squamous cell carcinoma, two very common types of skin cancer, are considered highly curable and have been linked to those who spend a considerable amount of time outside and thus are frequently exposed to the sun. Melanoma, though less common, is recognised as more serious and potentially life-threatening. Resulting from the rapid growth of the aforementioned melanocyte cells, melanomas tend to manifest as red, brown, or pink mole-like formations or even form moles themselves.
For men, melanoma generally develops on the head or neck, and for women, it is often found on the legs, arms, or other extremities. That being said, melanoma can certainly develop in other areas of the body (wherever melanocytes are found), including the mouth, eyes, and even the gastrointestinal tract. Unlike squamous and basal carcinoma, melanoma is seen largely in those who have experienced sunburns from excessive exposure to the sun’s UV rays.
Identifying Melanoma
Although the three types of skin cancer are generally considered curable if detected early enough, the possibility of early detection is largely contingent upon one’s own self-examination. To help with identification of melanoma-related areas, the American Academy of Dermatology has created an easy and helpful system. If your ageing loved one is concerned about a particular mole or series of moles, help him or her follow the ABCDEs of melanoma.
- Asymmetry: If you were to draw a line right down the middle of the mole and both sides looked the same (or symmetrical), there’s a good chance it is benign. If, however, the two sides don’t match (or are asymmetrical), it could be a melanoma.
- Border: Pay close attention to the border of the mole. Benign moles generally have smooth borders, while melanomas have irregular or notched borders.
- Colour: Another warning signal is if the mole has more than one colour, including multiple shades of brown, black, or tan. Additionally, melanomas may become red or blue in appearance.
- Diameter: While benign moles are smaller in size, melanomas tend to be about ¼ inch or larger (or about the diameter of a pencil eraser).
- Evolving: Many of the characteristics listed above may change over time for a mole, in which case you will want to monitor closely. If other changes develop – such as itching, crusting, or bleeding – it could also indicate melanoma.
Risk Reduction
As mentioned previously, older adults – those 65 years of age or older – are more likely to develop skin cancer than any other age group. The correlation behind this is not complex; seniors have lived longer than others and have had greater exposure to the sun’s UV rays. However, with some extra precaution, seniors can reduce their overall risk of skin cancer. Below are a few helpful tips.
- Avoid tanning beds altogether.
- Use effective sunblock (at least SPF 15).
- Avoid going outside between the hours of 10 am and 4 pm, if possible.
- Wear proper clothing (hat, sunglasses, light, loose-fitting shirts) to protect against UV rays.
- Find shade whenever possible.
- Examine your skin regularly (following the ABCDEs), and follow up with a medical professional, if you suspect there may be a problem.
