Skin cancer refers to the abnormal growth of skin cells, typically caused by the unrepaired damage to DNA in skin cells. There are several types of skin cancer, including basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma, which is the most dangerous form. Exposure to ultraviolet (UV) radiation from the sun or artificial sources, such as tanning beds, is a significant risk factor for developing skin cancer.
BCC is the most common type of skin cancer. It usually appears as a raised, pearly bump or a pinkish patch of skin. BCC typically grows slowly and rarely spreads to other parts of the body. However, if left untreated, it can cause damage to surrounding tissues and structures.
Although less common than BCC or SCC, melanoma is the most aggressive and potentially deadly form of skin cancer. It develops from pigment-producing cells called melanocytes. Melanoma can arise from an existing mole or appear as a new dark spot on the skin. It may exhibit an irregular shape, uneven borders, different colors within the lesion, or undergo changes in size or appearance over time. Melanoma has a high likelihood of spreading to other parts of the body if not detected and treated early.
SCC is the second most common type of skin cancer. It often appears as a scaly, red, or rough skin patch or a raised growth with a crusty surface. SCC can grow quickly and has a higher risk of spreading to nearby lymph nodes or other organs if left untreated.
Signs and symptoms of skin cancer can vary depending on the type and stage of the disease.
It is important to regularly examine your skin and be aware of any changes or abnormalities. If you notice any suspicious skin lesions or have concerns about skin cancer, it is crucial to seek medical evaluation and consultation with a dermatologist.
Early detection and treatment greatly increase the chances of successful outcomes for skin cancer.
Therapeutic options for skin cancer depend on factors such as the type, stage, and location of the cancer, as well as the individual’s overall health. Here is a brief overview of common therapeutic options for skin cancer:
Surgical
excision
The primary treatment for most skin cancers involves surgically removing the cancerous lesion along with a margin of healthy tissue to ensure complete removal. This procedure is typically performed under local anesthesia and may be done as an outpatient procedure.
Cryotherapy
Liquid nitrogen is used to freeze and destroy precancerous and cancerous skin cells. This treatment is often used for superficial skin cancers or small areas of involvement.
Mohs micrographic
surgery
This specialized surgical technique is used for certain types of skin cancer, especially those with high recurrence rates or located in critical areas. The surgeon removes the cancerous tissue layer by layer and examines each layer under a microscope to ensure complete removal while minimizing the loss of healthy tissue.
Targeted
therapy
Some types of advanced or metastatic skin cancers may be treated with targeted therapies. These medications specifically target the genetic mutations or proteins that drive cancer growth, helping to inhibit tumor growth and prolong survival.
Radiation
therapy
High-energy radiation is targeted at the cancerous cells to destroy them or prevent their growth. It may be used as the primary treatment for certain types of skin cancer or as adjuvant therapy after surgery to kill any remaining cancer cells. Radiation therapy is typically administered over several sessions.
Immunotherapy
Immunotherapy drugs stimulate the body’s immune system to recognize and attack cancer cells. They are often used to treat advanced or metastatic skin cancers and can have durable responses in some cases.
Topical
medications
For certain superficial skin cancers, topical medications such as creams or gels containing immune response modifiers, chemotherapy agents, or photodynamic therapy agents may be prescribed. These medications are applied directly to the skin to target and destroy cancer cells.
The specific treatment plan will depend on the individual’s unique circumstances, and a multidisciplinary approach involving dermatologists, oncologists, and other specialists may be employed. Early detection and treatment offer the best chance of successful outcomes in skin cancer management. It’s important to consult with our healthcare professional to determine the most appropriate therapeutic options for your specific skin cancer.

Preventing skin cancer involves adopting sun-safe behaviors and taking precautions to minimize your exposure to harmful ultraviolet (UV) radiation. Here are some recommendations to help reduce your risk of developing skin cancer:
Apply sunscreen
Use a broad-spectrum sunscreen with a sun protection factor (SPF) of 30 or higher on all exposed skin, including your face, neck, arms, and legs. Apply it generously and reapply every two hours or after swimming or sweating.
Perform regular
self-examinations
Check your skin regularly for any new or changing moles, spots, or lesions. Pay attention to any growths that are asymmetrical, have irregular borders, exhibit multiple colors, or change in size or appearance. If you notice anything suspicious, consult a dermatologist.
Seek shade
When the sun’s rays are strongest, typically between 10 a.m. and 4 p.m., seek shade under trees, umbrellas, or other structures. This reduces your direct exposure to intense UV radiation.
Get professional
skin examinations
Consider having regular skin screenings performed by a dermatologist, especially if you have a personal or family history of skin cancer or significant sun exposure.
Wear protective
clothing
Cover your skin with protective clothing, such as long-sleeved shirts, pants, and wide-brimmed hats. Look for clothing with a tight weave or special UPF (ultraviolet protection factor) rating for added sun protection.
Be cautious around
reflective surfaces
UV rays can bounce off reflective surfaces like water, snow, sand, or concrete, increasing your exposure. Take extra precautions when spending time near such surfaces.
Use
sunglasses
Protect your eyes from harmful UV rays by wearing sunglasses that block 100% of UVA and UVB radiation. Look for sunglasses labeled as providing UV protection.
Teach sun-safe
habits to children
Educate children about the importance of sun protection and encourage them to adopt sun-safe practices, such as wearing sunscreen, seeking shade, and wearing protective clothing and hats.
Avoid tanning
beds
Tanning beds emit harmful UV radiation, increasing your risk of skin cancer. It’s best to avoid them altogether.
Be aware of
medications
Some medications can increase your sensitivity to sunlight. If you’re taking any medications, consult your healthcare provider or pharmacist to determine if sun protection measures are necessary.
Remember!
Prevention is key, but it’s never too late to start practicing sun safety. Incorporating these recommendations into your daily routine can help reduce your risk of developing skin cancer and maintain healthier skin in the long run.
