5 Essential Facts for Understanding and Preventing Skin Cancer


Understanding and preventing skin cancer, a globally widespread cancer type, is a significant public health issue. Skin Cancer Awareness Month in May emphasizes the need for public education about skin cancer’s risks and the necessity for prevention. This article aims to offer detailed insights into skin cancer, including its varieties, causes, prevention measures, and treatment options, aligning with Skin Cancer Awareness Month’s objectives.

Comprehending Skin Cancer

Skin cancer arises when skin cells undergo mutation and proliferate uncontrollably, leading to a mass or tumor. This tumor can either be benign (non-cancerous) or malignant (cancerous). The primary skin cancer types include basal cell carcinoma, squamous cell carcinoma, and melanoma.

Basal Cell Carcinoma (BCC)

Basal Cell Carcinoma is the most prevalent form of skin cancer. It affects the basal cells in the epidermis’ lower part. BCC often presents as a pearl-like bump or a slightly shiny patch on the skin that may bleed or crust over.

Squamous Cell Carcinoma (SCC)

Squamous Cell Carcinoma originates in the squamous cells, which form the skin’s middle and outer layers. SCC generally appears as a hard, red nodule or a flat lesion with a rough surface.


Melanoma is the most lethal type of skin cancer. It stems from melanocytes, the cells that contribute to skin pigmentation. Melanoma often mimics moles; some even evolve from moles. While most melanoma lesions are black or brown, they can also be skin-colored, pink, red, purple, blue, or white.

Skin Cancer Causes

The main cause of skin cancer is exposure to ultraviolet (UV) radiation from the sun or tanning beds. However, other risk factors include fair skin, a history of sunburns, excessive sun exposure, residing near the equator or at high altitudes, having numerous or abnormal moles, a family history of skin cancer, a compromised immune system, and exposure to radiation or certain substances.

Preventing Skin Cancer

Prevention lies at the core of Skin Cancer Awareness Month. Here are some crucial strategies for skin cancer prevention:

  1. Avoid Sun Exposure: Limit your sun exposure during peak hours (10 a.m. to 4 p.m.), when UV rays are most potent.

  2. Use Sunscreen: Apply a broad-spectrum sunscreen with an SPF of 30 or higher on all exposed skin, even on overcast days and during winter.

  3. Cover Up: Whenever possible, wear protective clothing such as long-sleeved shirts, wide-brimmed hats, and sunglasses.

  4. Stay Away From Tanning Beds: UV radiation from tanning beds can lead to skin cancer and should be avoided.

  5. Examine Your Skin: Regular self-checks can help detect skin cancer early when it’s most treatable.

Skin Cancer Treatment

The treatment for skin cancer depends on the cancer type, size, location, stage, and the patient’s overall health. Options may include surgery, radiation therapy, chemotherapy, immunotherapy, targeted therapy, or a combination of these.


Skin Cancer Awareness Month is a vital reminder of the continuous fight against skin cancer and the importance of prevention. By understanding skin cancer and adopting measures to protect our skin, we can significantly lower our risk and promote overall skin health.
