Skin cancer is the most common form of cancer in humans. The term “cancer” itself refers to an abnormal proliferation of cells resulting in a tumour. These malfunctioning cells can rapidly divide and multiply, and spread to other parts of the body - a dangerous and often fatal process called “metastasis”. Skin cancer occurs when these abnormal cells originate in the layers of the skin, and they are named after the type of skin cell from which they arise. In most cases, as long as the cancerous cells remain in the top layers of the skin, the epidermis, the risk of metastasis and spreading of the cancer to other organs remains low.
Once the cancer cells grow deeper into the layers of the skin, the skin cancer becomes more life-threatening. Thus, catching cancer early and preventing the growth of the malignant cells deeper into the skin is essential.Skin cancers are divided into two main categories: melanoma, and non-melanoma skin cancers. The non-melanoma skin cancers are Basal Cell Carcinomas(BCC) and Squamous Cell Carcinomas(SCC). Together, BCC, SCC and melanoma can take on a variety of shapes and sizes. Definition Melanoma is a malignant tumor of melanocytes.
A mole on the right shoulder brings prudence, discretion, a faithful marriage partner and very industrious. On the left shoulder, satisfied with any position in life both socially and occupationally. (ad) Wrist – Frugal, ingenious and dependable. On a woman, one marriage. On a man, possibly two marriages. Signification: Twin Moles.
Melanocytes are cells that produce melanin, the dark pigments responsible for the color of skin. Melanoma is the most rare, but most dangerous form of skin cancer when detected in a late stage. Fortunately, with early detection the survival rate is 98%. Signs Melanoma can appear in moles or spots on the surface of your skin, even in areas not exposed to the sun. In more rare cases it can appear in the eye or bowel.
There are four major kinds of melanoma, divided based on clinical and pathological features: superficial spreading melanoma (SSM), nodular melanoma, lentigo malignant melanoma (LMM) and acral lentigious melanoma. “Melanoma is the most rare, but most dangerous form of skin cancer when detected in a late stage.”. C - coloursColour can help distinguish a normal mole from an abnormal one. Healthy moles usually have one even colour, while irregular moles can contain multiple shades of colour. It is also important to make note of any blue or white colours that may be present in your moles, as this is a sign that the mole may be cancerous.

If your mole has multiple colours or shades, you should speak with your doctor.The mole in the left image is monotone and is healthy. The image on the right contains multiple shades of red and is cancerous. E - evolutionNoting any changes with respect to size, shape, colour, or features is an important factor in catching cancer early. If your mole develops symptoms like itching, tenderness or bleeding, or is evolving in any way over time, this is a warning sign to seek medical attention immediately.
This is why it is important to not only check your moles regularly, but also to look for any changes that may have occurred since the last you performed.The image shows the evolution of a mole over time. While not every mole will evolve, or evolve in the same way, even minor changes are important to track and share with your doctor. Definition Basal Cell Carcinoma (BCC) is the most common cancer to mankind, with an estimated 2.8 million cases diagnosed each year in the and 50-60,000 cases per year in.
BCC develops from the basal cells in your epidermis. Tanning and UV radiation from the sun contributes to the growth of BCCs, which are commonly found on sun-exposed areas of the body such as the face and neck. Although it is quite common, BCC is rarely fatal, since it grows slowly, often taking months or years to develop, and is highly unlikely to metastasize (spread to other organs of your body). Nonetheless, a BCC has the tendency to invade into deeper tissue, and thus can be quite disfiguring if it is not properly treated. Signs Because of the long growth period, BCCs can vary in size from a few millimeters to several centimeters in diameter. There are several different clinical types of BCCs.
Definition Squamous Cell Carcinoma (SCC) is the second most common type of cancer in humans, with rates as high as 700,000 cases per year in the and over 20,000 cases each year in. SCC arise from the keratinocyte cells of your epidermis. In many cases, SCC begins with precancerous lesions called actinic keratoses (AKs), which are spots on the skin resulting from years of sun exposure and sun damage. While the majority of AKs either regress or remain AKs, a small percentage of them will turn into SCC. The condition is considered precancerous as long as the damaged cells remain in the epidermis. If left untreated, the actinic keratosis cells can begin to invade deeper layers of the skin and develop into cancer.

Both AK and SCC are most often found on areas of the skin with high exposure to the sun,. Sun exposure is a high risk factor for SCC just like it is for BCC. However, compared to BCC, squamous cell carcinomas are more likely to metastasize and spread to other organs. Signs SCC can present itself in many different ways such as scaly plaques, open sores that may crust or bleed, or even as red patches of skin resembling eczema. Sometimes, SCC can even look like a wart or an elevated growth.
Precancerous AK can initially be hard to spot, or nearly invisible, often starting out as a rough patch of skin. AKs are slow-growing, and can eventually appear as a combination of pink, red, dark tan, or skin-coloured spots. They can become inflamed, and in some instances,. In most cases, AK will regress or remain AK without developing into SCC, however it is important to monitor their development and ensure the condition does not worsen.
