Cancer that is produced in skin tissues is called Skin Cancer. It is one of the most common cancer types which affects both men and women. This cancer affects around one million people per year and this is caused by several factors like prolonged sun exposure, tanning, poor immune systems etc. Read on to get a better understanding of this most common type of cancer and take steps to avoid it.

How does it affect cancer in the skin?
When the skin cells abnormally change and expand, the uncontrollable growth causes the creation of a mass known as a tumour. Also known as a lesion is this tumour that develops in the skin, and these cancerous growths are malignant in nature, causing the death of adjacent cells leading to spontaneous growth. These tumours migrate through the bloodstream, and even affect other remote organs during advanced skin cancer stages.
Skin Cancer Types
Skin cancer is classified into two forms, based on how far they can spread. Non-melanoma and melanoma are both forms of skin cancer. Non-melanoma contains in it the form of basal cell carcinoma and squamous cell carcinoma.
- Melanoma-The cancer that affects the melanocytes or the pigment-creating skin cells.
- Basal cell carcinoma-The cancer that affects the lower epidermis or the outer skin layer.
- Squamous cell carcinoma-cancer affecting the squamous cells or the flat cells forming the surface of the skin.
Basal cell carcinoma and squamous cell carcinoma do not normally spread to other parts of the body while melanoma is a dangerous form of skin cancer that spreads to other parts of the body. The key ratio and most common type of skin cancer are the forms of carcinoma with the least component representing the aggressive melanoma.
The Skin Cancer Signs
The skin cancer signs are changes in the skin that require time to treat along with ulcers. Skin discoloration and variations in skin moles can also be observed on occasion. The most common symptom is a thin, bright and pale lump in colour, or a firm red lump. Some cancer forms are often associated with rough and scaly patches, or smooth red or brown scaly patches. In such cases, beware of any new suspicious development and consult a doctor. While most of the time these growths are painless, at times they can also be painful.
In cases of basal cell carcinoma a smooth round bump is usually formed on the head, shoulder, or neck with signs of crusting and bleeding with tumour growth. A thick red colour patch may be formed in squamous cell carcinoma, along with ulcer and bleeding. In cases of melanomas, brown or blackish lesions form. As a symptom of the melanoma being malignant, the lesion shows a change in scale, colour or shape.
