Melanoma

Melanoma is considered as the most dangerous form of skin cancer

Introduction

What is melanoma?

Melanoma is considered the most dangerous form of skin cancer as it typically will spread to other areas of the body, including organs, if left untreated.

Non-melanoma skin cancers, such as Squamous Cell Carcinoma and Basal Cell Carcinoma, are generally considered less dangerous as they are less likely to spread and can usually be treated with surgery. It can occur anywhere on the body, including areas not exposed to the sun, like inside the mouth or the palms of the hands. Men are more likely to get melanomas on their back while women are more likely to experience them on their legs.

Melanoma begins in melanocyte cells. It occurs when those cells behave abnormally, growing excessively and taking over surrounding tissues. They can develop from existing moles or skin growths, but, more commonly, they will start as a new growth.

“Although melanoma can develop by coincidence, most cases of melanoma are likely caused by radiation from sunlight; some studies even put incidences of skin cancer caused by sun exposure at around 95%.”

All about Melanoma

Causes

Everyone is at risk of getting Melanoma, however not everyone has the same risk as a large variety of factors can cause it. From personal or family history to outside behaviour – there is a lot that can impact skin health.

Symptoms

It is crucial to stay on top of your moles, even when you have been watching yourself thoroughly. There are many symptoms to look out for, especially suspicious or changing moles are important to keep a close eye on.

Types

Melanoma is often segmented into four different types. Three of them start relatively in situ, although this can definitely change over time. One type, however, can be invasive right from the start and may spread to other parts of the body quickly.

Prevention

Melanoma is the most dangerous skin cancer and can do some serious harm, however when the right prevention methods are used it can be caught early. There are many ways to prevent it from forming, some more obvious than others.

Melanoma has been on the rise for years for different reasons. Increased tanning, low awareness and more sun exposure during holidays.

Early detection is the key to treating it. The earlier it is found, the more treatment options there are.

Make sure to self-check your whole body every 3 months if you have more than 50 moles. In other cases, do it at least twice per year.

Frequently asked questions about
melanoma.

There are four main types of melanoma:

Superficial spreading melanoma: This is the most common type, accounting for about 70% of melanoma cases. It can occur anywhere on the body, but is found more frequently in the upper back, legs in women and torso in men.

Lentigo maligna: This is the most common form in the elderly and it is most likely to appear in sun-exposed areas, especially head and neck

Acral lentiginous melanoma: This is the most common form of melanoma found in people with darker skin, mainly individuals with African ancestry. It is most frequently found on the sole of the feet, palm of the hands or beneath the nail.

Nodular melanoma: The most aggressive form, corresponds to 10-15% of melanoma cases.

Other types like amelanotic and desmoplastic melanomas are rare.

The first melanoma warning signs often are the appearance of a new skin spot or an existing skin lesion that grows or changes in color or shape. You should pay attention to spots that look different from all of the other spots on your skin.

To help you keep an eye on your dangerous moles you can use the ABCDE rule to recognize the warning signs on it: Asymmetry ,Border irregularity, multiple Colours, Diameter greater than 6 mm and Evolution.If you notice these warning signs or if your skin spot is changing,visit a healthcare professional promptly. During medical examination your doctor will ask about symptoms, risk factors such as family history of skin cancer or sunburn and examine your skin to look for signs that may indicate melanoma. Any suspicious area will be removed and sent for laboratory analysis (this is called skin biopsy). Biopsy is the only sure way for the doctor to know if it is skin cancer.

Melanoma spreads when the tumor’s malignant cells travel through the bloodstream or lymphatic system to other parts of the body such as lymph nodes, tissues or organs.
