Screening and Prevention of Skin Cancer
The largest organ in the body is the skin. It offers defence from heat, sunburn, harm, and illness. Additionally, the skin regulates body temperature and stores vitamin D, water, and fat. The epidermis (top or outer layer) and the dermis are the two primary layers of the skin (lower or inner layer). The epidermis is where skin cancer develops.
Overall, it is noted that the balance of advantages and disadvantages brought about by medical professionals checking patients’ skin is uncertain; nonetheless, it is recommended that checking patients’ skin may assist avert very detrimental patient outcomes caused by skin cancer, such as death.
Let’s talk prevention.
People with ashen skin typically acquire skin cancer more frequently than those with a darker complexion. Nevertheless, the following traits put people at risk: Skin cancer risk factors include:
a) The patient’s prior skin cancer incidence;
b) A family history of skin cancer;
c) Pale skin, freckling, a propensity for sunburns;
d) History of organ transplantation; and
e) The use of immunosuppressive medications. Age is also a risk factor for skin cancer in the elderly.
For people of all ages, it is advised to limit their skin’s exposure to the sun. Instead of finding shade, it is encouraged to make an effort to avoid being in the sunlight. It’s also advised to wear clothing that covers the majority of the skin, as well as hats with wide brims that allow for face and neck shading and footwear that completely covers the feet. Additionally, people are advised to take vitamin D supplements and wear sunglasses with lenses that absorb UV sunlight.

the use of broad-spectrum sunscreens with a minimum SPF of 30; these should be applied 15 to 30 minutes before leaving indoor spaces, and all exposed skin should be reapplied every 2 hours, as well as after swimming or vigorous perspiring. However, caution should be exercised around extremely young children because sunscreens may not be suitable for their skin type. For such people, it is best to stay out of the sun; using infant carriages with covers that provide shade may be advised. It’s also highly recommended for elderly adults limit their time in the sun, especially given their increased risk of skin cancer.

What is Screening?
The goal of screening is to find cancer before a person experiences any symptoms. This may aid in the early detection of cancer. Early detection of cancer or abnormal tissue may make treatment simpler. When symptoms start to show up, cancer may already be spreading.
It’s crucial to keep in mind that just because your doctor recommends a screening test, it doesn’t necessarily mean you have cancer. You can get screening tests even if you don’t have any signs of cancer.
Researchers examine screening procedures to identify the ones that cause the fewest side effects and provide the greatest benefits. The goal of cancer screening trials is to determine whether early detection increases lifespan or lowers the risk of death from the disease. If the disease is identified and treated early, there may be a greater chance of recovery for some types of cancer.
A skin cancer examination may be done by both the patient and the doctor.
Skin cancer can be screened by using both a visual self-exam by the patient and a detailed clinical examination by a healthcare professional. A doctor or nurse will examine your skin to look for moles, birthmarks, or other pigmented areas that have unusual-looking colour, size, form, or texture.
A biopsy is typically performed if an area of the skin appears suspicious. With a local excision, the doctor will cut away as much of the questionable tissue as possible. The tissue is then examined under a microscope by a pathologist to look for cancerous cells.
There are now mobile phone “apps” that analyse skin lesions to find skin cancer and malignant melanoma. To determine if these apps are reliable and helpful for skin cancer screening, more research in extensive testing programmes is necessary.

Risks of Screening Tests :
It’s possible to have false-negative test results. Results from screening tests may seem normal even when cancer is present. Even if there are symptoms, a person who receives a false-negative test result—one that indicates there is no cancer when there is—may postpone seeking medical attention. Test results that are falsely positive can happen. Results from screening tests may seem abnormal even when cancer is not present. A false-positive test result (one that indicates cancer when there isn’t any) can be stressful and is typically followed by additional tests (such as a biopsy), which come with their risks. Scarring may result from a biopsy. The doctor will attempt to leave the tiniest scar during a skin biopsy, but there is a chance of infection and scarring.
Conclusion
It is suggested to use the ABCDE mnemonic to help you remember what to look for during a typical visual inspection. Asymmetry, border irregularity, nonuniform colour, dimension bigger than 6 mm, and evolving make up this acronym. It is emphasised, nonetheless, that to use the mnemonic effectively, a greater comprehension of the many types of skin cancer and their signs is necessary. Therefore, it is essential to be well-versed in skin cancer as well.
