Overview:
Skin cancer occurs when cells of the skin grow abnormally and form a lesion. It most often develops on skin exposed to the sun but can also occur on areas of your skin not ordinarily exposed to sunlight.
Skin cancer is categorized into three different types; basal cells, squamous cell, and melanoma. The first two types are non-melanoma skin cancers, which are highly curable. However, malignant melanoma is a rare type of cancer and harder to treat. It can quickly spread to nearby tissue and cells from the point of origin. Hence, it is necessary to have a timely intervention.
What are the symptoms you need to look out for?
In the early stages, skin cancer only occurs as a tiny lump or lesion and often get mistaken for other skin conditions. However, each type of skin cancer causes a specific set of signs and symptoms. Symptoms of each type of cancer are:
Basal cell carcinoma
- Raised translucent bumps on the skin that are smooth and pearly
- Pink or red lumps with a crusted centre
- Small blood vessels appearing on the lump or lesion
- Red scaly patches with irregular edges
- Ulcer and bleeding in patches
- Dome-shaped bump with a rough surface and an indented centre
- Moles that are asymmetrical and abnormal
- Mole changing color or diameter
- Red ulcers that itch and bleed
- Spots or growths of various colors, ranging from brown to black
- Fair skin, which has less pigment and protection from the UV rays.
- Severe sunburns
- Excessive sun exposure
- Frequent use of tanning beds
- Moles
- Weak immunity
- History of skin cancer in the family
- Skin examination: They will check your skin to determine whether your skin changes are likely to be skin cancer. If they suspect cancer, further testing may be needed to confirm that diagnosis.
- Skin biopsy: They will remove a sample of suspicious skin and send it to the lab for testing. These tests can determine whether you have skin cancer and, if so, what type of skin cancer you have.
- Cryosurgery: They will destroy precancerous cells by freezing them with liquid nitrogen.
- Excisional surgery: They will cut off the cancerous tissues along with the surrounding tissues.
- Mohs surgery: They will remove cancer along with the affected skin. The surgeon will remove the cancer layer by layer to save as much skin as possible.
- Curettage or electrodesiccation: They will scrape away the cancerous cells using an electric needle.
