These are the most common form of skin cancer. They are caused by frequent and repeated exposure to the sun. There are several different types of carcinoma..

Basal cell carcinoma is the most widespread. It makes up 90% of all skin cancers. The carcinoma type is brought on by sunburn in adults: 20% of individuals over the age of 50 are affected... This carcinoma never metastasizes .

Squamous carcinoma (10% of all cases) is associated with a greater risk. If located on ears or lips, it can metastasize.

• Who is affected?

Anyone can be affected. Nonetheless, carcinomas are more common in fair-skinned individuals living in a sunny climate.

• Is it serious?

Carcinomas are rarely fatal. They progress slowly. Early diagnosis allows for simpler treatment and improves the patient's chances of recovery.

It is a malignant tumor formed from melanocytes, the cells that produce melanin (which is the pigment responsible for tanning). Melanomas usually take the form of a brown or black spot, found either on normal skin or, more rarely, on top of an existing mole. Melanomas appear to be associated with intense, short-term exposure, especially the kind responsible for sunburn.

• Who is affected?

Unlike carcinomas, melanomas can occur at any age. Although half of all melanomas are found in individuals over 50, this is also one of the most common cancers in young people. (Melanomas are, however, rare among children: the average age at diagnosis is currently estimated at 30 years old).

• Is it serious?

Although it is the rarest type, malignant melanoma is considered to be the most dangerous form of skin cancer. Because of its ability to metastasize, this form of melanoma must be diagnosed as early as possible. The earlier the diagnosis, the better the chance of recovery.

In the majority of cases, melanoma sufferers can recover fully if their treatment begins during the cancer's first stage of development. It is imperative to consult your dermatologist rapidly if you find a suspect lesion.
