When investigating the early stages of skin cancer, it is important to know the signs of its three types: basal cell cancer, squamous cell cancer and melanoma.

Early basal cell cancer - Basal cell carcinoma signs and symptoms

Three out of four cases of basal cell cancer are located on the head and neck of the patients. The common locations are face (nose, eyelids, lips, cheeks, forehead, temples), scalp and upper trunk, but basal cell carcinoma can also be located on other areas of the body. It takes the form of a button highlighted in red or pink, small red spots or white with a raised curb, or a sore that does not heal.

Early squamous cell cancer - Squamous cell carcinoma signs and symptoms

Squamous cell carcinoma often appears on sun-exposed areas (head and neck, upper body, forearms, hands and nails), but can also affect other areas such as the mouth or genitals. On the skin exposed to sunlight, they often begin as a white crust (keratosis) which gradually thickens and becomes an ulcerated wound with a raised irregular border.

Early Melanoma - Melanoma signs and symptoms

Melanoma can appear suddenly in a previously normal skin, or more rarely on a pre-existing mole (melanocytic nevi) particularly if it occurred at birth.

At first, it appears as a colored spot of a few millimeters, which has several colors of brown and / or black. It is often skewed and has an irregular border. Melanoma can evolve fairly rapid in size, shape, contours and colors. Other symptoms, such as surface modification, the presence of a protuberance or a lump, an extension of the pigment, bleeding (late sign that we should not wait to see) or itching can sometimes be observed. Melanoma can affect any area of the skin, scalp, mucous membranes (mouth, genitals ...) or nails.

Types of melanoma

Superficial Spreading Melanoma is the most common variety (70% of cases) and matches the description above. This melanoma usually affects individuals aged 40-50 years - sometimes much younger. Superficial Spreading Melanoma develops anywhere on the body but most often on the back in men and lower limbs in women.

Nodular melanoma (10-15% of cases) forms a fleshy growth of brown or black, with a faster evolution. Acral melanoma (2-10% in subjects with white skin) generally develops in the palms, soles and nails. At the level of polish, a brown band, like a bar code can be indicative of melanoma beginner. This type of melanoma is particularly common in subjects with black skin or pigmentation.

Melanoma Dubreuilh is the rarest form of melanoma (5% of cases), it forms a brown spot, wide and irregular, usually located on the face of those aged over 60 years, its evolution is slower.
