The primary forms of skin cancer include basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell carcinoma and squamous cell carcinoma are typically non-malignant and progress slowly. In contrast, melanoma is malignant and tends to grow rapidly. Other types of skin cancer include Kaposi’s sarcoma and cutaneous T-cell lymphoma. Early detection and treatment significantly increase the chances of curing most cases of basal cell and squamous cell skin cancers.
Skin Cancer Symptoms
The most common indication of skin cancer is a change in the skin. This could manifest as a new growth, a sore that doesn’t heal, or alterations in an existing growth. Skin cancers vary in appearance, and the ABCD technique aids in diagnosis:
A stands for Asymmetry:
Normal moles are symmetrical, but potentially cancerous moles are not. Check for asymmetry by mentally dividing the mole and observing if the sides match. While not all asymmetrical moles indicate skin cancer, regular examination is a proactive measure to identify potential concerns.
B stands for Border:
Healthy moles typically have smooth, clearly defined borders. Examine mole borders closely; irregular, notched, or feathered borders may suggest skin cancer.
C stands for Colour:
Ordinary moles exhibit a range of colors from light tan to dark brown. Suspicious moles may have multiple colors, such as various shades of brown, tan, or black within a single area. Moles can also appear blue, red, or white.
D stands for Diameter:
Moles suggestive of skin cancer often grow rapidly from a small to a larger size. If you notice a mole enlarging, it’s advisable to consult a doctor for further evaluation.
Regular self-examination is recommended for identifying changes in the skin. While not all changes indicate cancer, it’s crucial to report any alterations to a healthcare provider promptly. Seeing a dermatologist, who specializes in diagnosing and treating skin conditions, may be necessary. Despite practicing sun safety, regular skin checks remain important, as early detection increases the likelihood of successful treatment and cure for skin cancer.
