What Is Skin Cancer, and what are the different kinds of skincancer?
Skin cancer is caused by he abnormal growth of skin cells, mostly due to DNA damage from UV rays. There are three common types:
- Basal cell carcinoma: involves deep skin cells, rarely spreads but can grow locally.
- Squamous cell carcinoma: appears on sun-exposed skin, can spread if untreated.
- Melanoma: most dangerous type, can spread early, deadly without swift treatment.
Identifying Skin Cancer (Signs & Symptoms)
Knowing what to look for saves lives.
- Look for new growths, non-healing sores, or dark spots with irregular shape, border, or color.
- “ABCDE” method helps check moles: Asymmetry, Border irregularity, Color changes, Diameter over 6mm, Evolving size/shape.
- SCC appears as scaly, sometimes sore patches. BCC as pearly bumps. Melanoma often appears as a striking “ugly duckling” compared to other moles.
Skin Cancer Treatment Options
- Surgical excision is standard for most skin cancers, providing a high cure rate.
- Mohs surgery is preferred for facial and high-risk cancers.
- Immunotherapy and targeted therapy help fight advanced or spread cancers, especially melanoma.
- Topical treatments and photodynamic therapy assist with superficial cases.
Skin Cancer Prevention: How to Lower Your Risk
- Wear broad-spectrum SPF 30+ sunscreen, reapply every 2 hours when outdoors—even on cloudy days.
- Avoid sun at midday, use hats, sunglasses, and seek shade when possible.
